Fits like a glove

Fits your GMC Yukon XL like a glove

The floors in your Yukon XL have been scanned with lasers - a tried-and-true method to make sure these floor mats fit every corner of your GMC.  Your set of floor mats are designed to fit your car, not anyone else’s.

All-weather protection

All-weather GMC protection

You have full protection in all environments, including messy kids, snow, mud and dirt.  Since these WeatherTech DigitalFit mats work like a tray, it’s incredibly easy to get the messy liners out of your GMC, spray them down, and put them back in.

More value when you sell

More value when you sell your GMC Yukon XL

Your original Yukon XL flooring will remain in pristine condition, which means - in most cases - your vehicle will be more valuable when you sell or trade-in your vehicle.  Your carpeting won’t be subjected to normal wear and tear.

Match your interior

Match your Yukon XL's interior

Black, gray, or tan.  And cocoa for some applications.  Choose whichever color best matches your GMC Yukon XL.  While black is the most popular, and looks great with all interiors, we also have tan, gray and cocoa in certain applications.

Works like a tray

Works like a tray

This means that they aren’t flimsy or rubbery, so dirt & spills will remain ON the mat when you take them out of your Yukon XL.  You can grab the floor mat with one hand and its shape will stay the same. WeatherTech DigitalFit is able to accomplish this with a patented blend of materials.

Stays in place

Stays in place in your GMC Yukon XL

These floor mats aren’t going to move around.  They are 100% custom fit to your Yukon XL with a backing that helps them stay in place.  These also feature retention devices if your GMC has built-in retention devices (like a hook or anchor) on the driver’s side.

Keeps spills from your feet

Keeps spills from your feet

If you spill your drink on the floor, the mats have a channel design that will direct the spill to the bottom of the mat and away from your feet.  This is designed so that you can keep driving to your destination without worrying about getting your feet dirty.

Lifetime limited warranty

Lifetime limited warranty

As an authorized retailer, you’re protected for as long as you own your GMC Yukon XL.  WeatherTech’s Limited Lifetime Warranty ensures that you’re protected from any manufacturer’s defects in materials or workmanship.  Excludes normal wear and tear.
