The ReadyLift 69-3411 4"/1" SST Lift Kit provides your 2011-2019 GM 2500HD/3500HD with a rugged, tough stance, allowing for larger tires and increased ground clearance. This cost-effective lift solution does not require permanent modifications to your truck and features a true bolt-on design.
This SST Lift Kit includes a pair of heavy-duty tubular steel upper control arms engineered to match your truck's strength. It also features 2011-UP HD-specific lift-oriented ReadyLift forged torsion keys, offering an adjustable lift while maintaining the factory ride quality. These super-strong forged torsion keys are stronger than stock and uniquely indexed for this kit. CNC-machined differential drop spacers lower the differential, positioning the front CV axles into a safe factory angle on 4WD trucks—2WD trucks will not use the diff spacers.
To lift the rear of your truck, the ReadyLIFT SST Lift Kit includes OEM-style 1.0" cast iron rear lift blocks complete with new U-bolts and hardware. The kit also features new, super-strong tie-rod end assemblies to replace the weaker factory versions. These heavy-duty steering assemblies are much stronger than the OEM units and install easily. Such attention to detail is unmatched by other lift kits for GM HD trucks.
Please note that front shocks are required but not included.

- 4" front lift / 1" rear lift
