Product Details
The ReadyLift 3" SST Lift Kit is made for the 2020-2025 GMC Sierra 2500 HD, giving it more ground clearance and room for larger tires.
Designed to improve stance, performance, and capability, this kit includes everything necessary to clear up to 35" tires. Along with the outward appearance changes to the new GM HD, General Motors also made changes to the long-standing torsion bar suspension. These changes required ReadyLIFT to engineer a new SST lift kit that are specifically designed to function and install properly on this new suspension design.
Our dedication to professional engineering and manufacturing has yielded a new 3" SST lift kit system that comfortably allows for 35" tires.
