We recently had the opportunity to upgrade a 2020 GMC AT4 Sierra 1500 with a Ready Lift 1.75'' leveling kit. The result was a truck that stands tall and proud, ready to conquer any terrain. The leveling kit improved the appearance and ride comfort, while also providing additional ground clearance. Installing the kit was a simple and seamless process, and the end result was nothing short of outstanding. The GMC AT4 Sierra now boasts a level stance and a more confident look, ready to tackle any road conditions with ease. This Ready Lift leveling kit was the ideal choice for the Sierra, and we are confident that the owner will be thrilled with the results.
