GMC Sierra Floor Mats: Cab & Trim Fit | TuxMat

Quick answer: The right Sierra floor mats come down to your cab style and year, not your trim. Our TuxMat® sets are laser-measured for the Sierra 1500 Crew Cab, the Sierra 1500 Double Cab, and the Sierra HD Crew Cab, each scanned to its own floor layout. Pick your cab and model year on the product page and you land on the correct set. The Crew Cab options also account for the available rear under-seat storage, so check that detail on the page before you order.

A Sierra is a work truck and a daily driver rolled into one. Job sites in the morning, kids in the afternoon, gravel and salt the whole way through. The factory carpet was never built for that double life, and once grit grinds into the weave it does not come back out. Full-coverage mats are how you keep the cab looking sharp while it earns its living.

Cab style is the first decision

Sierra floor pans differ by cab, so that is where fitment starts. A Crew Cab has a full-size rear seat and a longer rear floor than a Double Cab, which changes the second-row mat shape. Our TuxMat® lineup covers the 2019 and newer Sierra 1500 Crew Cab, the 2019-2026 Sierra 1500 Double Cab, and the 2020-2026 Sierra HD Crew Cab.

Pick the cab that matches your truck first, then confirm the year on the product page. Getting the cab right is what makes the rear coverage sit flush instead of bunching or leaving gaps.

The rear storage detail on Crew Cab models

Here is a Sierra-specific thing worth knowing. The Crew Cab sets are built for trucks with the optional rear under-seat storage, which changes the rear floor area. The product page calls this out, so if your truck has that storage feature, you are in the right place, and if you are not sure, the fitment notes on the page will tell you. This is exactly why the product page is the source of truth rather than a generic chart.

Why custom coverage matters in a truck

Truck footwells are deep and full of the spots that collect debris, the dead pedal corner, the area around the seat tracks, the wide center hump. On a Sierra that sees mud and road salt, those bare edges take the worst of it.

TuxMat® delivers up to 2.5x more coverage than factory floor mats¹, out to the door sills and wrapping the center tunnel. TuxMat® holds a 4.8★ rating based on 5,000+ Google Ratings, and Car and Driver confirmed it after testing: "Hands down, these floor mats offered the most comprehensive interior coverage of any floor mats we tested." The raised edges, formed by the 6mm EVA foam middle layer, hold slush and mud in place so it does not migrate into the carpet.

TriForce™ Construction, Built for the Daily Grind

Every Sierra set is built on our TriForce™ three-layer construction. The top is a water-resistant PVC vinyl with a leather-textured finish that wipes clean and resists salt, mud, and spills. The middle is the 6mm EVA foam that creates the tall sidewalls and stays flexible in the cold. The bottom is an anti-skid cloth that grips the carpet without adhesive so the mat does not shift when you climb in with work boots.

To be clear about the material, the top layer is water-resistant rather than sealed shut. It is built to protect against the salt, mud, and spills a truck deals with daily and block debris at the source.

How to confirm the right Sierra set

Open the product page for your cab, the 1500 Crew Cab, the 1500 Double Cab, or the HD Crew Cab. Select your model year and confirm the rear storage note if your truck has it. The page flags any restriction so the fit is right before you buy. You can see the rest of the lineup at the full TuxMat® collection.

Frequently asked questions

Does my trim change which mats I need?

No. Within the same cab and year, SLE, SLT, AT4, Denali, and the rest share the floor pan, so the same scanned set fits.

What is the difference between Crew Cab and Double Cab mats?

The rear floor is longer in the Crew Cab, so the second-row coverage is shaped differently. Pick the cab that matches your truck.

I have a Sierra HD. Is that a separate set?

Yes. The HD Crew Cab has its own scanned set covering 2020-2026. Use that page rather than the 1500 listing.

Is there a warranty?

Yes. Every set carries our Limited Lifetime Warranty against defects in materials and workmanship, plus a 30-Day Money-Back Guarantee if the fit is not right for you.
