The 2022.5 Interior Trap: Why Your Floor Mats Won't Fit Your New Sierra
Share
You just traded in your trusty 2020 GMC Sierra for a brand-new, completely redesigned 2024 GMC Sierra 1500 AT4. The new exterior looks stunning, but the interior is an absolute masterpiece, featuring a massive new infotainment screen and a completely re-engineered center console with an electronic precision shifter.
Before you leave the dealership, you grab your expensive, heavy-duty laser-measured floor liners out of your old truck and try to drop them into your new AT4.
You instantly hit a wall.
The inner edge of the front floor liner violently collides with the new center console. It won't sit flat, the factory retention posts don't line up, and the plastic lip is hovering two inches above the carpet.
You just fell directly into the 2022.5 Interior Trap.
Because GMC completely overhauled the cabin architecture during the mid-year 2022 refresh, the physical dimensions of the floorboards and center console drastically changed. If you try to carry over your old mats—or if you accidentally order parts for a "2021" online—they will absolutely not fit your new truck.
You don't have to ruin your new carpet. You just need the right laser measurements.
In this guide, we explain exactly how premium interior engineers at WeatherTech and Husky Liners use advanced 3D lasers to map the exact millimeter of the newly refreshed Sierra cabin. We'll show you how to identify your exact interior layout, why cheap seat covers block your side airbags, and how to safely armor your $70,000 investment.

Frequently Asked Questions (Interior Accessories)
Will adding cheap seat covers to my Sierra trap the side-impact airbags?
Yes, and it is incredibly dangerous.
Modern GMC Sierra seats have sensitive airbag modules sewn directly into the outer bolsters. If you buy a cheap, universal $30 seat cover from an auto parts store, it acts like a straightjacket, physically preventing the airbag from deploying in a crash. Premium custom-fit covers from Covercraft are engineered with highly specific, breakaway safety stitching that allows the factory airbags to deploy flawlessly.
Can I run an under-seat storage box with a massive rear floor liner?
Yes, but you may need to trim the liner.
Both WeatherTech and Husky Liners make incredible under-seat storage boxes, but they are designed to bolt down to the factory floor. If you buy a massive, full-coverage rear floor liner that extends all the way under the seat, the lip of the liner might interfere with the storage box sitting flush. Many premium rear liners feature molded "trim lines" allowing you to easily cut away the excess plastic to perfectly accommodate the storage box.
Do premium floor liners actually stay in place without sliding?
Yes, they lock into the factory floor posts.
Universal mats slide around, which is incredibly annoying and highly dangerous if they jam under your brake pedal. WeatherTech and Husky Liners are digitally mapped to utilize the exact factory retention posts built into your GMC's carpet. You simply press the liner down over the posts, and it is locked securely in place.
