Leveraging one of our top-selling application designs for the AT4 and TrailBoss 1500 trucks, our engineers adapted the quality and features into the all-new AT4X and ZR2. Forget squeaks, rattles, and vibrations; these lift kits ensure superior performance with smooth rides over all terrain. Designed to provide more ground clearance and increased flexibility on the street or trail, the big lift kits utilize boxed steel front/rear cross members and a full-width front skid plate constructed of thick 3/16" plate steel. New 1/4-inch boxed plate steel differential drop brackets feature a double gusset and boxed center rib to take the abuse of front differential torsional twisting on the big kits.Our Big lift kits feature heavy-duty angled and offset top mount strut extensions that realign the struts to optimize shock performance and minimize wear. A specially designed lower mount strut pre-load spacer offers the added benefit of a slight increase in spring rate to better manage unsprung mass resulting from the larger wheels and tires finding their way onto this newly lifted truck. To lift the rear, new fabricated steel rear blocks with integrated bump stop landings are added as well as new rear shock extensions to retain the factory performance shocks.With thousands of engineering and development hours and more awesome features than we could possibly mention, these are the best lift kits available on 2026 GM 1500 ZR2/ZT4X trucks!

Fast, friendly service! Eric was a pleasure to work with in taking care of an insurance claim for my damaged truck bed topper for my 2007 Ford F150. The new topper was delivered and installed the very next day! It looks great...a lot better than the one I had on there!!! I highly recommend Leer Truck Accessories of Conyers for all your truck accessory needs!
I understand now why LEER has such high reviews. Blake and Justin create an environment that is completely stress free. Their knowledge and communication skills are top notch. My trailer hitch install was complete in less than an hour. Make the call, you won't be disappointed!!

Wonderful people to work with. I have had both a Tono cover and mudflaps installed. They even helped finish up a taillight installation that I almost completed. These are the best people that I know to go get anything for your truck. I would recommend them highly!
Called the night before for a repair on the trailer. They were there at the exact time they said they would be and was very quick with the service. The technicians were very kind and polite, they even explained some parts and how they worked. Will definitely be back if i have any issues in the future when in the area.
Good job done. Friendly and fast. What else could I ask for.
I recommend for anyone needing upgrades to their vehicle. I was in and out in an hour for my lightning installation. I'll be back.

Ordered a half cover for the bed of my F-250. The cover arrived the next morning. Appointment to install so I could watch it being completed, so I can remove later. The young man that sold me the cover as well as installed the cover was absolutely great. He explained everything patiently with excellent communication skills and instruction. This was a very pleasant experience THANKS!
