SmartCoverage™ Custom Fit Floor Liners for the 2020-2026 GMC Sierra 3500 HD (Crew Cab Models (Provides over-the-hump coverage. Fits VINYL models)) is purpose-built, not trimmed down from a universal mat. Every contour is laser-measured against your Sierra 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.

Why You’ll Love It

• Wall-to-Wall Coverage — a true custom pattern for your cabin, built to match the factory layout rather than approximate it
• Weatherproof by Design — waterproof, stain-resistant TPE resists staining and won’t break down from repeated exposure to moisture and road salt
• Odorless & Non-Toxic — BPA-free materials with no off-gassing or chemical smell
• Low-Maintenance by Design — a quick rinse or wipe-down is all it takes to keep it looking new
• No-Slip Surface — a textured finish that resists shifting under hard braking or turns
• Limited Lifetime Warranty — built to outlast the life of your vehicle
