2020-2026 Chevrolet Silverado 3500 HD Floor Liners|Double Cab Models (OTH w/ rear under-seat storage)|SMARTLINER

SmartCoverage™ Custom Fit Floor Liners for the 2020-2026 Chevrolet Silverado 3500 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 Silverado 3500 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

• Exact-Fit Engineering — every edge is measured against your cabin’s real dimensions, so there are no awkward gaps or overlaps
• Non-Toxic Construction — formulated to be safe around kids and pets, with no lingering odor
• Weatherproof by Design — waterproof, stain-resistant TPE resists staining and won’t break down from repeated exposure to moisture and road salt
• Removable & Washable — pulls out in one piece for fast cleaning, then drops right back into place
• Secure Retention — anti-skid texture and factory-matched attachment points keep it locked in place, even over rough roads
• Confidence Built In — a Limited Lifetime Warranty stands behind every set

Every dimension here traces back to the Silverado 3500 HD’s actual floor layout. Whether you’re working with the Gasoline version and the Double Cab configuration, this set covers 2 Row Floor Liners with 1st Row Over The Hump Coverage, Second Row Liner, and Second Row Full Coverage Liner. Comes in Black to blend right in.
