2019-2022 Duramax 3" SST Lift Kit (69-3030)

Fits

ReadyLift had dedicated a significant amount of time developing this kit to work seamlessly with the newer Duramax pickups. Aside from the physical appearance, GM also updated the torsion bar system within these trucks. These forged torsion keys are built specifically for this newer system, have indexing designed for each unique application, allowing 3" of adjustable front lift height, and give you proper clearance for 35" tires. Differential drop spacers also allow you to retain proper CV axle angles, factory geometry, and ride quality.

• 20x " by 9" +0 offset - 35" by 12.50" tire
• Silverado and Sierra have different fender-well opening sizes - some minor trimming may be required depending on the true tire size and design

• Use of Auto 4 Hi feature not recommended
• Works with trucks equipped with either the OE #84461807 or OE #84634344 factory torsion keys and requires ReadyLIFT torsion key unloading tool 66-7822B or similar for installation
•  When setting the torsion key adjustment bolt, do not exceed 27.5” from the wheel center to the fender edge. Exceeding this will create a top-off condition, meaning the suspension has little to no down travel. The result is poor ride quality and premature wear of components
• Please take into account tire and wheel choice, this will generally have a meaningful impact on the ride & handling experience.
