UnderCover 24-26 Ford F150 5.7ft Bed w/ Pro Access TG Elite LX Bed Cover

Factory-Color-Matched Hard Tonneau That Protects Your Cargo and Keeps It Invisible

The UnderCover UNDUC2238L-UM Elite LX Bed Cover is the premium factory-color-matched one-piece hard tonneau for the 2024-2026 Ford F-150 with a 5.7-foot bed. The UNDUC2238L-UM is finished in Carbonized Gray Metallic (UM) to match the factory exterior color, delivering a seamless, factory-installed appearance that distinguishes it from black universal covers. The Elite LX features UnderCover's FiberMax composite construction lighter and stronger than traditional fiberglass with a UV-resistant automotive-grade clearcoat finish applied over a factory-matched base coat. The gas strut assist lifts the cover with one hand and holds it fully open at 90 degrees. Central locking integrates with the tailgate lock, and the cover includes a weathertight seal around the full perimeter. The UNDUC2238L-UM provides a low 6.5-inch profile to keep cargo concealed and streamline the roofline of the truck.

Frequently Asked Questions

What color is UM on the UnderCover Elite LX?

UM is the Ford paint code for Carbonized Gray Metallic, used on 2021-2026 F-150 models. The UNDUC2238L-UM cover is painted and clearcoated to match this specific factory color code.

Does the UNDUC2238L-UM fit the 2024 and 2025 F-150 with Pro Power Onboard?

The cover fits the 2024-2026 F-150 with a 5.7-foot bed. Verify that your specific bed does not have factory bed-rail mounted accessories that conflict with the rail clamp mounting system before ordering.

Is this cover compatible with a spray-in bed liner?

Yes. The UNDUC2238L-UM installs via bed rail clamps that sit on top of the bed rail, making it compatible with spray-in and drop-in bed liners.

Can I still access the full bed with this cover?

Yes. The gas-strut assisted lid lifts to 90 degrees and stays open without a prop rod, giving full access to the entire bed floor from the tailgate.

How does the lock work on the Elite LX?

The UNDUC2238L-UM central lock mechanism integrates with the tailgate latch. When the tailgate is locked, the cover is locked. A separate key cylinder is also included for locking the cover independently.

Will this cover improve my F-150 fuel economy?

Hard tonneau covers reduce aerodynamic drag from an open bed. At highway speeds, a closed hard cover can reduce bed turbulence and may contribute to marginal fuel efficiency gains.

Is the UNDUC2238L-UM covered by a warranty?

Yes. UnderCover backs the Elite LX with a limited lifetime warranty to the original purchaser against defects in materials and workmanship.

Does this cover work with the F-150's factory tie-down cleats inside the bed?

Yes. The Elite LX mounts on the bed rail and does not block the factory bed floor or tie-down cleats, which remain fully accessible.

Installation Instructions

1. Unbox and lay the UNDUC2238L-UM cover face-down on a clean, padded surface. Inspect for shipping damage before proceeding.
2. Open the tailgate and clean the top surface of both bed rails thoroughly.
3. Position the cover at the cab end of the bed, aligning the front edge parallel to the cab back wall.
4. Attach the front mounting clamps to the bed rail at the cab end. Hand-tighten only at this stage.
5. Attach the rear mounting clamps near the tailgate end. Verify the cover is centered and parallel with both rails before tightening.
6. Tighten all mounting clamps to the specification provided in the included instructions.
7. Connect the latch mechanism to the tailgate striker following the instructions for your specific tailgate configuration.
8. Test the gas-strut open and close function. Verify the cover seals evenly on all four sides when closed.
9. Test the lock cylinder and tailgate lock integration. Confirm the cover cannot be opened when locked.
