ALMULOO Rear Wheel Well Liners for 2021-2026 Ford F-150 (2PC) Black PE Plastic, Direct-Fit Replacement

ALMULOO rear wheel well liners are a direct-fit replacement for 2021–2026 Ford F-150 (except Raptor), restoring underbody protection with two durable PE plastic liners that match factory contours.

These replacement wheel well liners are molded to match the factory RL3Z-9927886-B contours and clip locations, providing a straightforward way to renew protection for the inner fender area on 2021–2026 Ford F-150 trucks (not compatible with Raptor or Lightning). Made from high-density polyethylene (PE), the pair helps shield critical sheet metal and components from road debris, salt, and moisture that accelerate corrosion and noise. The kit includes both left and right liners plus the installation hardware required to complete the swap.

How will these liners protect my F-150 during daily driving?

ALMULOO liners block gravel, mud, water splash, and road chemicals from direct contact with inner fender metal and suspension parts, reducing wear and corrosion risk. Their molded shape also helps reduce airborne road noise that enters the cabin from the wheel wells.

• Molded PE plastic resists impacts and repels moisture.
• Full-coverage design deflects debris from inner body panels.
• Helps limit road noise through added barrier between tire and cabin.

Will these liners fit my specific F-150 model and trim?

These liners are manufactured to fit 2021–2026 Ford F-150 models that use factory part RL3Z-9927886-B and are compatible with both 2WD and 4WD drivetrains. They do not fit Raptor or Lightning versions—confirm your vehicle's part number or consult a dealer if unsure.

• Direct replacement for part number RL3Z-9927886-B.
• Supports both 2WD and 4WD configurations.
• Not intended for Raptor or Lightning model applications.

How difficult is installation and what comes in the kit?

The kit includes both driver- and passenger-side liners plus the installation hardware necessary for a typical replacement. No printed manual is included; many owners follow online video guides, and some vehicles may require additional drilling or professional assistance for ideal fitment.

• Complete two-piece set with hardware included.
• Designed to align with factory clips and bolt locations.
• Additional drilling may be required on certain trucks; pro installation recommended for exact fit.

How durable are these liners in different climates and road conditions?

Constructed from high-density polyethylene, the liners balance rigidity with flexibility so they retain shape in heat, cold, and under impact from road debris. The material resists water absorption and chemicals commonly found on roads, helping maintain protection season after season.

• PE plastic resists cracking in cold and softening in heat.
• Impact-resistant design tolerates small stone strikes and debris.
• Corrosion-resistant material protects metal components beneath.

If you drive in regions with gravel roads, winter salt, or frequent off-road exposure (non-Raptor), this kit provides a practical way to prolong the life of your truck’s rear inner fenders.
