SmartCoverage™ Custom Fit Floor Liners for the 2020-2026 GMC Sierra 2500 HD (Double Cab Models (OTH w/ rear under-seat storage)) is purpose-built, not trimmed down from a universal mat. Every contour is laser-measured against your Sierra 2500 HD’s own floor, so the fit is exact — right down to factory mounting points — and the waterproof, stain-resistant TPE construction stands up to whatever the cabin sees next.

What Makes It Different

• Custom, Laser-Measured Fit — engineered to your vehicle’s exact floor contours for true edge-to-edge coverage, not a generic trim-to-fit mat
• Odorless & Non-Toxic — BPA-free materials with no off-gassing or chemical smell
• Removable & Washable — pulls out in one piece for fast cleaning, then drops right back into place
• Weatherproof by Design — waterproof, stain-resistant TPE resists staining and won’t break down from repeated exposure to moisture and road salt
• Stays Put — textured, non-slip surface keeps contents from sliding around
• Made to Last — Limited Lifetime Warranty coverage, no fine print surprises
