AEV 37" Tire Clearance Kit for 2024+ GMC Sierra 2500 AT4X AEV Edition

The 2024+ GMC Sierra 2500 AT4X AEV Edition is purpose-built for adventure, ready to take on challenging trails with its advanced suspension, factory skid plates, and aggressive 35″ tires. But for drivers who want to push the limits even further, stepping up to 37″ tires is the ultimate upgrade—delivering extra ground clearance and the confidence to tackle bigger obstacles. The challenge? The stock setup just isn’t designed for tires this large. Many owners find that fitting 37″ tires leads to rubbing, restricted wheel travel, and even potential damage when the terrain gets rough.

That’s where the AEV 37″ Tire Clearance Kit makes all the difference. Engineered specifically for your Sierra, this all-in-one kit comes with precision brackets, trim templates, plastic closeouts, and replacement lower fender flare extensions—everything you need to safely and confidently run 37×12.50″ tires on factory wheels or 37×13.50″ on AEV Salta XD Wheels. With these upgrades, your larger tires can move and flex as they should, even in extreme off-road conditions, without rubbing or causing harm to your truck.

We’ve also chosen materials that closely match your Sierra’s OEM plastics, so the kit blends right in with the factory look. The result is a clean, professional appearance paired with the rugged performance you expect from your AEV-equipped Sierra.
