The ReadyLIFT 69-30300 SST lift kit provides a factory-style, engineered 3" front and 1" rear lift for compatible GM HD trucks. This kit includes SST-specific forged torsion keys, rear blocks, and front inner fender brackets to clear larger tires while maintaining ride quality and durability. Designed to allow up to 35" tires and to work with the updated torsion bar suspension on newer GM HD models.
*Special installation/compatibility note: When setting the torsion key adjustment bolt, do not exceed 27" from the wheel center to the fender edge. Exceeding this measurement will overlift the vehicle and create a top-off condition (very limited down travel), causing poor ride quality and premature component wear. Some fender well trimming may be required for maximum tire/wheel combinations; variances may exist between Silverado and Sierra models.
