The 2024+ Chevrolet Silverado 2500 ZR2 Bison is already one of the most capable off-road trucks you can buy, built to handle tough terrain with advanced suspension, rugged protection, and aggressive 35″ tires. But if you’re looking to push your truck even further, upgrading to 37″ tires is the next step—giving you more ground clearance and the confidence to tackle obstacles that would challenge even the best stock setup. Unfortunately the factory setup just doesn’t provide enough clearance for 37″ tires. Many owners quickly find that upsizing from the stock 35″ tires leads to rubbing, limited wheel movement, and even potential damage, especially when the trail gets tough.
That’s where the AEV 37″ Tire Clearance Kit comes in. Designed specifically for your Silverado, this comprehensive kit includes precision-engineered brackets, trim templates, and plastic closeouts—everything you need to safely and confidently run 37×12.50″ on factory wheels or 37×13.50″ on AEV Salta XD Wheels. With these components, your larger tires can rotate and flex freely, even in extreme off-road conditions, without rubbing or causing damage to your vehicle.
We’ve carefully selected materials that closely match your truck’s OEM plastics, so the kit blends seamlessly with your Silverado’s factory look. The result is a professional, integrated appearance with the rugged performance you demand.

No. The front closeouts are specific to the AEV bumper. Non-ZR2 Bison bumpers do not provide enough clearance for this size of tire.
37x12.5 tires will work with factory wheels and this clearance kit. However 37x13.5 tires will require lower offset wheels, such as the AEV Salta XD, for backside clearance while turning. This is due to frame clearance not the closeout kit.
AEV recommends a 37x12.5 tire on OEM Bison/AT4x AEV edition wheels or 37x13.5 tire on AEV Salta XD (28401136/28401137) aftermarket wheels. Packaging is very tight and going taller or wider will likely cause tire rubbing.
This kit does require minor trimming of the front body mount. However, this modification is hidden by the AEV closeouts and would also be hidden by the factory components if the vehicle were ever returned to stock.
The Chevy Silverado ZR2 Bison has larger front fender openings than the GMC Sierra AT4X AEV Edition, which allows 37" tires to clear the OEM fenders and flare extensions without modification. Only the front bumper closeout area requires modification on Chevy Bison.
