Built for serious work and heavy-duty performance, the Worksport AL4 Flip-Up Tri-Fold Hard Tonneau Cover is engineered specifically for the Ford F-250 Super Duty and Ford F-350 Super Duty.
Designed to handle the demands of job sites, towing, and long-haul travel, the AL4 features rugged aluminum panel construction that delivers superior strength and reliable cargo protection. Whether you're hauling tools, equipment, or gear, this cover keeps everything secure while maintaining a clean, low-profile look.
The flip-up tri-fold design provides maximum flexibility—open one section for quick access or fold it fully when you need the entire bed for larger loads. A weather-resistant seal system helps protect your cargo from rain, dust, and debris, making it ideal for both work and everyday use.
With a no-drill installation that mounts directly to factory bed rails, the Worksport AL4 is a straightforward upgrade that enhances both the functionality and appearance of your Super Duty truck.
