Trifecta ALX Bed Cover 99-16 Super Duty 6.6ft

The Trifecta ALX Bed Cover 99-16 Super Duty 6.6ft by EXTANG is engineered for Ford Super Duty owners who demand protection without compromise. Whether you're hauling tools, securing cargo on job sites, or protecting your truck bed from weather and UV damage, this tonneau cover delivers the durability and functionality that serious truck owners expect. The 6.6-foot bed length makes it ideal for standard Super Duty configurations, fitting seamlessly with factory bed dimensions while maintaining clean truck aesthetics.

EXTANG's Trifecta ALX system combines aluminum construction with a low-profile design that minimizes wind resistance and drag penalties. The cover's tri-fold mechanism allows full bed access when needed, while the clamp-down design provides security without drilling into your truck bed—a critical feature for preserving resale value and avoiding potential rust initiation points. The aluminum extrusions are corrosion-resistant, crucial for trucks exposed to salt, moisture, or harsh industrial environments. At 34.73 lbs, the cover remains manageable for single-person operation while maintaining structural rigidity necessary to handle snow load and highway speeds.

This cover fits Ford Super Duty models from 1999 through 2016, covering both single and dual rear wheel configurations with the standard 6.6-foot bed. Fleet operators, contractors, and daily-driver truck owners benefit equally from the weatherproofing and security this system provides. Installation requires no permanent modifications to your truck bed—a non-invasive approach that keeps options open for future accessory additions. The dimensions (31 x 6 x 74 inches when folded) ensure compact storage and easy handling during the setup process.
