GMC Sierra 1500 Tonneau Cover - BAK - BAKFlip MX4 (GEN 3) Hard Folding - Matte Black - 2019–2026. A sturdy, low-profile hard folding cover engineered for the New Body Style Sierra 1500 to protect cargo while maintaining full bed access.

The BAKFlip MX4 (GEN 3) combines reinforced aluminum top panels with high-density polymer cores for increased strength (about 22% over the original MX4) and a textured matte-black finish that resists wear. Re-engineered auto-latching panels and upgraded lock components improve security. Revised EPDM perimeter seals, an extended dual-action tailgate seal and integrated drain tubes help keep cargo dry. The cover folds toward the cab for 100% bed access and supports more than 400 lbs (evenly distributed). Installation is faster thanks to redesigned rails and a click-in, no-drill clamp design that enables one-person fitting on compatible beds.

Features

  • High-density polymer-reinforced aluminum panels — ~22% stronger than original MX4
  • Supports 400+ lbs when evenly distributed
  • Re-engineered auto-latch and improved lock components
  • EPDM perimeter seals and 13% longer dual-action tailgate seal
  • No-drill click-in rail and clamp design for quicker installation
  • Folds toward cab for full bed access; integrated drain tubes
  • Textured matte-black finish; fits 2019–2026 New Body Style Sierra 1500 (including CarbonPro; fits with or without Multi-Pro/Multi-Flex tailgate)
