Product Description

The Westin 19-44735 Hard Tri-Fold Tonneau Cover is engineered specifically for 2020-2026 Chevrolet Silverado 2500 HD, Silverado 3500 HD, GMC Sierra 2500 HD, and Sierra 3500 HD trucks fitted with the 82.2-inch long bed. Built with heavy-duty aircraft-grade aluminum panels on an extruded aluminum alloy frame, this cover delivers the security and rigidity of a hard tonneau while offering the everyday convenience of a tri-fold design. Squeeze-lever-activated panels fold back in three sections for partial or full bed access without removing the cover.

Installation requires no drilling - a custom-fit under-bedrail clamp system secures the cover flush with the bed rails for a clean OEM look that also reduces wind resistance. EPDM rubber seals provide full-perimeter weather protection, while an integrated drainage system keeps the bed dry in all conditions. With a 661 lb. static weight capacity and a limited lifetime warranty, this cover is built to meet the demands of heavy-duty truck owners.
