The RetraxONE MX retractable tonneau cover, part number RTX60378, is designed for 2021–2027 Ford F-150 models with a 5.5-foot bed, including the F-150 Lightning, without stake pockets. Its one-piece, aluminum-reinforced polycarbonate construction provides dependable impact resistance, UV protection, and long-term durability. The textured matte black finish and low-profile design sit flush with the bed rails for a clean appearance while preserving rear visibility.
The sealed cover incorporates an advanced water management system with integrated drain tubes to help direct moisture away from your cargo. CoreTrax™ technology uses maintenance-free precision ball bearings and a custom track system for smooth, jam-resistant operation in demanding conditions. The compact canister features a spiral track system that minimizes friction, scuffs, and wear during retraction. Engineered to perform in temperatures from -50 to 200 degrees Fahrenheit, the RetraxONE MX helps protect truck-bed contents from weather, dirt, and unauthorized access.
A spring-loaded handle enables convenient one-handed operation, while the cover can be locked in any position along the rails for flexible cargo management. This allows you to carry oversized items while keeping the remaining bed area covered. The cover supports up to 200 pounds of evenly distributed cargo when properly installed and operated according to the manufacturer’s instructions.
Installation is simplified with the integrated clamp-on mounting system, requiring no drilling, cutting, or permanent vehicle modifications. Most installations can be completed in under 60 minutes using basic tools and the included hardware. The RetraxONE MX is engineered and assembled in the USA and includes a 1-year warranty supported by Retrax product experts and customer service based in the United States.
