2" 2025-2026 GMC Sierra 1500 AT4 SST Lift Kit by ReadyLift

The ReadyLIFT 69-35200 SST Lift Kit for the GMC Sierra 1500 AT4 is the perfect solution for owners looking to add lift to their factory-equipped trucks safely and effectively. Specifically engineered for models with the factory 2" front lift, this kit avoids the common issues associated with traditional leveling kits, such as ball joint binding and CV axle contact. The SST Lift Kit works harmoniously with the factory front shock and strut assembly to deliver 2" of additional front lift and 1" in the rear—resulting in a more aggressive stance and improved off-road capability.

This kit includes a top-mount strut spacer, a pre-load spacer to control droop, and premium heavy-duty upper control arms for added strength and proper alignment geometry. OE-style 3" tall cast iron rear lift blocks and bump stop extension cups round out the system, offering durability and enhanced performance. Designed as a complete bolt-on solution, the ReadyLIFT SST Lift Kit provides a reliable, factory-friendly upgrade that maintains ride quality and long-term reliability.
