Product Details

The Extang Trifecta Max is a premium soft folding tonneau cover engineered for long-lasting weather protection and a clean, low-profile appearance. Built with 80-grade TriShield vinyl featuring an upgraded 3-layer construction, the cover delivers outstanding all-weather resistance and fade durability so it maintains a like-new look season after season. The watertight design relies on robust triple-fin weather seals that are permanently integrated into the cover — not glued on — providing a reliable barrier against rain and moisture that outperforms conventional Q-seals and bulb seals.

Key Features:

  • 80-Grade TriShield Vinyl: Upgraded 3-layer construction for superior all-weather performance and fade resistance
  • Triple-Fin Weather Seals: Permanently integrated seals provide a watertight fit and outlast glued-on alternatives
  • Exclusive Corner Tuck System: Delivers tight, precise corners year after year for a consistently clean fit
  • Heavy-Duty Aluminum Frame with MegaBows: Industry-exclusive bow design prevents sagging under rain, hail, and snow; dual-pivot hinges reduce long-term wear
  • Spring-Loaded Clamp Installation: No support rails required — simply pull it out of the box and clamp it to the truck in about 5 minutes
  • Recessed Clamp Design: Clamps seat seamlessly into the bows, protecting the cover from puncture damage during opening and closing
  • Black Leather Grain Vinyl Finish: Standard profile with a refined look
  • Removable: Yes — mounting hardware included; no drilling required
  • Backed by a 10-year limited warranty

The Trifecta Max is a specific-fit cover designed for the 6 ft. 6 in. bed on select 2007–2014 Chevrolet Silverado and GMC Sierra 1500, 2500 HD, and 3500 HD models without a factory Cargo Management System. California residents: WARNING: Cancer and reproductive harm — www.P65Warnings.ca.gov.
