What Is Included In F-150 FX4 Package [2026 Complete Guide]

The Ford F-150 FX4 package isn’t just a decal on the side of your truck; it’s a factory-engineered off-road upgrade built for real-world terrain. Whether you’re researching your next purchase, evaluating a used truck, or just trying to understand what that “FX4 Off-Road” badge actually means, this guide gives you the most complete answer available anywhere.

So, what does the FX4 package include on the F-150? The FX4 Off-Road Package adds skid plates (front differential, transfer case, and fuel tank), an electronic-locking rear differential, off-road-tuned monotube shock absorbers, Hill Descent Control, all-terrain tires, and FX4 badging/graphics. It is available exclusively on 4WD models and can be added to XLT, Lariat, King Ranch, Platinum, and Limited trim levels, but is not a standalone trim level itself.

Keep reading, we cover every model year, every component in detail, how the 2025 FX4 package differs, what “FX4” actually stands for, and whether this package is worth it for your driving needs.

What Does FX4 Stand For?

This is one of the most common questions people have when they see the badge. “FX” in Ford’s naming convention stands for “F-Series eXtreme.” The “4” refers to 4-wheel drive capability. So “FX4” essentially means: F-Series extreme 4-wheel-drive package.

It is not the same as a 4×4. A 4×4 F-150 simply means the truck has four-wheel drive. The FX4 is a specific off-road package that adds hardware on top of a 4WD drivetrain. You can have a 4×4 F-150 without the FX4 package, but you cannot have the FX4 package without 4×4.

Quick answer: FX4 = F-Series eXtreme, 4WD. It is a factory off-road package not a trim level and requires 4-wheel drive.

What Does the FX4 Package Include? (Core Components)

Regardless of model year, the FX4 Off-Road Package is built around five core hardware upgrades. Here’s what every FX4-equipped F-150 gets:

1. Off-Road Tuned Monotube Shock Absorbers

This is the defining upgrade of the FX4 package. The standard F-150 uses twin-tube shocks; the FX4 upgrades to monotube rear shocks with revised valving and increased damping capacity. This type of shock runs cooler under sustained off-road abuse, responds faster to terrain changes, and maintains more consistent damping.

Ford has sourced these shocks from different suppliers depending on the model year. On the 2025 F-150, the FX4 shocks are sourced through Ford’s Tier 1 supplier network, not FOX Racing (which is exclusive to the Raptor), but purpose-built for the F-150’s weight and use case. Many owners ask, “Who makes the shocks on the 2025 Ford F-150 FX4?” The answer is that they are Ford-spec monotube units, not branded aftermarket shocks.

The suspension tune also includes recalibrated stability control to allow appropriate wheel travel without triggering unnecessary electronic intervention.

2. Skid Plates: Three-Piece Underbody Protection

The FX4 package includes three steel skid plates covering the most vulnerable underbody components:

Front differential skid plate: protects the front axle and differential housing from rock strikes
Transfer case skid plate: guards the two-speed transfer case, which sits low and is expensive to repair
Fuel tank skid plate: covers the plastic fuel tank against rocks and debris

These are stamped steel plates, not plastic. A common question is whether the 2024–2026 F-150 FX4 includes skid plates over the catalytic converter. The answer is no; that is not part of the standard FX4 skid plate set, though aftermarket catalytic converter guards are available separately.

The skid plates are worth having even if you never go off-road. They protect against road debris, high curbs, and steep driveway approaches that can catch a standard truck’s undercarriage.

3. Electronic Locking Rear Differential (E-Locker)

The e-locker is arguably the single most valuable component in the FX4 package. With the push of a button, the rear axle is mechanically locked, forcing both rear wheels to spin at the same rate regardless of traction conditions.

This matters most when:

One rear wheel is lifted or on ice/mud and has no traction
Climbing steep loose-surface grades
Recovering a stuck truck
Navigating uneven terrain where a standard open differential would send all power to the spinning wheel

The e-locker available through the FX4 package is the same unit available as a standalone option on some trim/engine combos, but bundling it in the FX4 package is typically the more cost-effective way to get it.

Does every F-150 with the FX4 package have a locking differential? Yes, the electronic locking rear differential is a core, non-optional component of the FX4 package on all model years from 2015 onward.

4. All-Terrain Tires

The FX4 package includes purpose-selected all-terrain tires with:

Reinforced sidewalls for puncture resistance
More aggressive tread blocks for grip on dirt, gravel, and mud
All-season ratings for year-round use

Specific tire brands vary by model year and production run. The 2016 F-150 FX4 typically came with Goodyear Wrangler AT/S tires; later model years have used Goodyear Wrangler TrailRunner AT or similar. The 2025 F-150 FX4 uses all-terrain tires sized appropriately for the selected wheel package.

5. Hill Descent Control

Hill Descent Control (HDC) automatically manages throttle and braking when descending steep grades, keeping the truck at a controlled, consistent speed so the driver can focus on steering. It operates between approximately 3–20 mph, depending on gear selection, and can be combined with low-range 4WD for maximum control.

6. FX4 Badging, Graphics, and Interior Touches

The visual package includes:

“FX4 Off-Road” decals on the rear quarter panels
FX4 badging on the tailgate or fenders (varies by year)
Unique off-road information display in the instrument cluster (showing 4×4 status, terrain mode, inclinometer on newer models)
Rubber floor mats (on some model year/trim combinations)

2025 F-150 FX4 Package: What’s New?

The 2025 F-150 received a significant refresh, and the FX4 package was updated accordingly. Here is what the 2025 Ford F-150 FX4 package includes and what changed:

Updated for 2025:

Revised monotube shock tuning calibrated for the 14th-generation F-150’s updated chassis geometry
Enhanced terrain management system with Normal, Tow/Haul, Sport, Slippery, Sand, Mud/Ruts, and Rock Crawl modes
Updated skid plate set to the same three-piece coverage, but with refined mounting for the redesigned frame
New instrument cluster display with dedicated off-road information screen showing pitch, roll, and 4×4 system status
Available with PowerBoost hybrid, many customers search specifically for the “2025 F150 PowerBoost FX4” combo. Yes, the FX4 package is compatible with the PowerBoost hybrid drivetrain and adds a significant low-speed torque advantage off-road
Wheel well liners: A frequently asked question: Does the 2025 FX4 package come with wheel well liners? On most 2025 configurations, full wheel well liners are included as part of the FX4 package

2025 FX4 Suspension Specs: The 2025 FX4 package uses Ford-spec monotube rear shocks (not FOX Racing, which remains Raptor-exclusive). The suspension is tuned specifically for the Gen 14 platform and does not include a factory lift. The FX4 does not raise ride height. Ground clearance improvement comes from the all-terrain tires and body geometry, not a lifted suspension.

Common question: “Does the F-150 FX4 off-road package have a factory lift?” No. The FX4 package does not include a lift kit. If you want additional ground clearance, aftermarket leveling kits or suspension lifts can be added after purchase.

FX4 Package by Model Year

2009 F-150 FX4

In 2009, the FX4 occupied a different position in Ford’s lineup; it was offered as both a package and a near-standalone trim variant. The 2009 FX4 included:

Skid plates for key underbody components
Limited-slip rear differential (not the electronic locker found in post-2015 models)
Off-road-tuned shock absorbers
All-terrain tires (typically BFGoodrich All-Terrain T/A)
Two-speed transfer case with manual shift-on-the-fly capability
Unique 18-inch wheels with a machined finish
Body-color grille surround and bumpers
Sport cloth seats with enhanced bolstering, rubber floor mats
Leather-wrapped steering wheel

The 2009 version is notably less capable than modern FX4 trucks. The shift to an electronic locking differential (replacing the limited-slip) in 2015+ significantly increased off-road capability.

2016 F-150 FX4

The 2016 FX4 debuted on the revolutionary aluminum-body F-150 platform introduced for 2015. The 2016 package included:

3.31 electronic-locking rear axle (optional upgrade to 3.55 or 3.73 ratios available)
Off-road tuned shock absorbers
Hill Descent Control
Three-piece skid plate set (fuel tank, transfer case, front differential)
“FX4 Off-Road” decals and a unique off-road instrument display
All-terrain tires (typically Goodyear Wrangler AT/S)

Available on: XLT, Lariat, King Ranch, Platinum with 4WD Compatible engines: 2.7L EcoBoost V6, 3.5L EcoBoost V6, 5.0L V8

2017 F-150 FX4

The 2017 model maintained all 2016 FX4 core components with these additions:

Updated FX4 graphics package with refreshed badging
Improved off-road information display in the instrument cluster
Hill Descent Control with enhanced calibration
Slightly revised shock tuning for better trail performance
Improved SYNC system integration with off-road features (enhanced backup camera integration, 4×4 system status display)

A common question about the 2017 FX4: “Question: What were the shocks in a 2017 Ford F-150 FX4 with a 5.0?” The 2017 FX4 used Ford-spec monotube rear shocks with off-road-specific valving, regardless of engine choice. The shock specification is tied to the FX4 package, not the engine.

2019 F-150 FX4

The 2019 FX4 represented a notable technology jump:

All core FX4 components (skid plates, e-locker, all-terrain tires)
Rock Crawl mode added to the terrain management system
Updated Hill Descent Control with an improved algorithm
Off-road-tuned shocks with refined valving
Option for 360-degree camera (when paired with appropriate trim/technology packages)
Revised FX4 badging

2019 Terrain Management System modes: Normal · Sport · Tow/Haul · Snow/Wet · Sand · Rock Crawl

2022 F-150 FX4

The 2022 F-150 FX4 carried forward the Gen 14 platform improvements:

All core FX4 components unchanged
Available on XLT with hybrid (2.7L PowerBoost), a popular combo
Compatible with the 802A and 302A equipment packages on XLT

A common question: “Does the 2022 F-150 XLT FX4 have off-road front suspension?” Yes. The FX4 suspension tune applies to both front and rear, with revised damping calibration for the front and rear. The front uses off-road-tuned twin-tube shocks (on most configurations) or monotube units, depending on trim.

FX4 Package on Specific Trims

One of the most frequently asked questions is how the FX4 interacts with different trim levels. Here’s a clear breakdown:

FX4 on XLT

The XLT is the most popular trim to pair with the FX4 package. On a 2025 F-150 XLT with FX4 (equipment group 302A is common), you get:

All core FX4 hardware (skid plates, e-locker, HDC, AT tires, monotube shocks)
The truck remains a workhorse with no premium interior additions from FX4 alone.
Adding the FX4 to an XLT is one of the best value combinations in the lineup.

FX4 on Lariat

Ford F-150 Lariat FX4 package adds all core off-road hardware to a truck that already has a leather interior, heated/cooled front seats, and a 12-inch SYNC 4 screen. The result is a genuine dual-purpose truck comfortable on the highway, capable on trails.

2025 F-150 Lariat FX4 components: All standard FX4 hardware plus the Lariat’s premium interior. The FX4 package does not add heated seats, navigation, or other interior features; those come from the Lariat trim or available packages.

FX4 on King Ranch

The King Ranch FX4 is a premium off-road package combining King Ranch’s Mesa Brown leather interior, unique badging, and high-end amenities with the FX4’s off-road hardware. A frequent question: “Does the 2025 F-150 King Ranch PowerBoost with FX4 come with skid plates?” Yes, all three skid plates are included when the FX4 package is ordered on King Ranch, regardless of drivetrain.

FX4 on Platinum

The Platinum FX4 package is relatively uncommon but available. Platinum buyers typically prioritize interior luxury, but the FX4 adds genuine trail capability. The skid plates, e-locker, and off-road shocks are unchanged regardless of trim level.

FX4 vs. 4×4: What’s the Difference?

This is one of the most searched questions among F-150 shoppers. Here’s the clear answer:

Feature	Standard 4×4 F-150	F-150 with FX4 Package
Four-wheel drive	✅	✅
Monotube off-road shocks	❌	✅
Electronic locking rear differential	❌ (open diff)	✅
Skid plates	❌	✅ (3-piece)
Hill Descent Control	❌	✅
All-terrain tires	❌ (highway tires)	✅
FX4 badging & graphics	❌	✅
Off-road instrument display	❌	✅
Terrain management system	Basic	Enhanced with Rock Crawl

Bottom line: A 4×4 F-150 has four-wheel drive. An FX4 F-150 has four-wheel drive plus hardware that actually makes it capable off-road. The e-locker alone makes a massive real-world difference in low-traction situations.

“Is a Ford F-150 FX4 a 4×4 truck?” Yes all FX4-equipped F-150s are 4WD trucks. But not all 4×4 F-150s have the FX4 package.

FX4 vs. Tremor vs. Raptor

FX4 vs. Tremor

The Tremor package is Ford’s more aggressive off-road option positioned above the FX4:

	FX4	Tremor
Tires	All-terrain (standard size)	33-inch all-terrain
Suspension lift	None	Yes raised ride height
Ground clearance	Moderate improvement	Significantly higher
Front locking diff	No	Available
Best use case	Light-to-moderate trails, winter roads	Serious off-road, rock crawling
Price premium	~$1,000	~$3,500–$4,500

The FX4 is a better daily driver. The Tremor is a better trail truck.

FX4 vs. Raptor

The Raptor is in a completely different category:

FOX Racing Live Valve shocks (not available on FX4)
37-inch tires standard (Gen 3 Raptor)
Significantly wider body and track
DOHC high-output engine options
Pre-runner style suspension travel
Designed for high-speed desert running, not just trail use

The FX4 package keeps your F-150 a balanced daily truck. The Raptor is a dedicated performance off-road vehicle with a substantial price premium ($20,000+).

How to Identify if Your F-150 Has the FX4 Package

Looking at a used F-150 and want to verify the FX4 presence? Here’s what to check:

Exterior:

“FX4 Off-Road” decals on both rear quarter panels
FX4 badge on the tailgate or fenders
All-terrain tires (look for aggressive tread pattern and “FX4” or “Off-Road” sidewall markings)
Visible skid plates under the truck (look between the front tires and under the cab area)

Under the Truck:

Three distinct skid plates: one under the front diff, one under the transfer case, and one under the fuel tank

Inside the Cab:

Hill Descent Control button (usually on the center console or dash cluster)
Off-road information display in the instrument cluster
Electronic locking rear differential button (labeled “LOCK” or “REAR LOCKER”)

On the Window Sticker / Carfax:

The FX4 package has Ford order code “41N” on most model years. You can verify this on any window sticker or build sheet

Is the F-150 FX4 Package Worth It?

For most buyers, yes. Here’s the value breakdown:

The e-locker alone justifies a significant portion of the cost. An aftermarket electronic locker costs $1,500–$3,000+ installed. The factory e-locker comes with full warranty coverage.

Skid plates protect against expensive damage. A cracked transfer case or punctured fuel tank can cost $2,000–$5,000+ to repair. The skid plates cost a fraction of one repair incident to replace.

Resale value. FX4-equipped trucks consistently sell for more on the used market. Buyers actively search for the package, and many will pay a premium for a factory-equipped truck over an aftermarket-modified one.

The FX4 package makes the most sense if you:

Live in an area with unplowed rural roads, dirt roads, or significant winter weather
Tow a boat on slippery launch ramps (the e-locker is excellent here)
Access remote work sites or hunting/camping areas
Want the capability without the cost of a Raptor or Tremor

It may not justify the cost if you:

Drive exclusively on paved highways
Never encounter loose, slippery, or uneven surfaces
Are you buying the truck purely for towing on pavement

FX4 Package Price and Cost to Add

The FX4 Off-Road Package is typically priced between $875–$1,095 depending on model year, trim level, and any required prerequisite packages. On the 2025 F-150, the FX4 package is approximately $995 on XLT, with slight variation on higher trims.

Can you add the FX4 package to an existing truck? No, the FX4 package is a factory-order option only. It cannot be dealer-installed after the fact. If you want FX4 components on a truck not equipped from the factory, each component (e-locker, skid plates, shocks) must be sourced and installed individually, which will cost significantly more.

Frequently Asked Questions

Is FX4 a trim level?

No. FX4 is an optional add-on package, not a standalone trim level. You order it on top of XLT, Lariat, King Ranch, Platinum, or Limited.

Does the FX4 package always include skid plates?

Yes, all three skid plates (front differential, transfer case, fuel tank) are standard components of the FX4 package on all model years. Some owner-reported confusion stems from used trucks where skid plates were removed by previous owners.

What does FX4 stand for?

F-Series eXtreme, 4WD. It signifies an extreme off-road capability package for the 4-wheel-drive F-Series lineup.

Does the FX4 package come with rubber floor mats?

This varies by trim and model year. On XLT configurations, rubber/vinyl floor mats are commonly included. On Lariat and above, all-weather floor mats are typically a separate option or part of an appearance package.

What is the difference between the FX4 and a standard F-150?

The biggest differences are the electronic locking rear differential, monotube shocks, and three-piece skid plate set, none of which come standard on any regular F-150 trim.

Does the FX4 package include a lift?

No. The FX4 package does not include any suspension lift. Ride height increase comes only from the slightly larger all-terrain tires, not raised springs or shocks.

Is the 2025 F-150 FX4 good off-road?

Yes, for its intended use case, light to moderate off-road trails, dirt roads, loose surfaces, snow, and recovery situations. It is not a dedicated rock crawler or high-speed desert runner, but it handles the vast majority of real-world off-road conditions that F-150 owners actually encounter.

Does the FX4 package always require 4WD?

Yes, without exception. The FX4 package is available only on 4×4-configured F-150s.

Conclusion

The Ford F-150 FX4 Off-Road Package is one of the most well-designed factory off-road upgrades available on any half-ton pickup. By combining an electronic locking rear differential, monotube off-road shocks, three-piece skid plates, Hill Descent Control, and all-terrain tires into a single coherent package, Ford delivers genuine off-road capability without requiring buyers to go full Raptor.

For the 2025 model year, the FX4 package is better than ever with an updated suspension tune, improved terrain management system, and compatibility with the PowerBoost hybrid. At under $1,000, it remains one of the best factory option values in the truck market.

Whether you’re ordering new or shopping used, knowing what’s included in the FX4 package helps you make a smarter decision and helps you get more out of your truck wherever the road ends.
