3.5"F / 1"R SST Lift Kit- GM Silverado / Sierra 2500 HD 2011-2019

ReadyLIFT Suspension Inc. is thrilled to offer a cost-effective lift solution for 2011-2019 Chevy and GMC 2500HD and 3500HD truck owners that won't permanently alter your vehicle. The 69-3411 SST Lift Kit is a genuine bolt-on solution that can lift the front of your HD truck up to 3.5 inches. Included in this impressive kit are heavy-duty tubular steel Upper Control Arms designed to match your truck's strength. ReadyLIFT forged torsion keys specific to 2011-2019 HD trucks provide an adjustable lift without compromising the factory ride, featuring a unique indexing design. The kit also includes CNC-machined differential drop spacers for 4WD trucks to maintain safe factory angles on front CV axles (2WD trucks skip this). To raise the rear of your GMC Sierra Denali or Silverado 2500 HD, the SST Lift Kit incorporates OEM-style 1.0" cast iron rear lift blocks with new U-bolts and hardware. Additionally, it replaces the weak factory tie-rod end assemblies with heavy-duty steering assemblies for increased strength. This kit is meticulously engineered and allows for up to 34" tall tires. Please note that longer front shocks are required (not included; we recommend ReadyLIFT SST3000 Performance Front Shocks designed for this kit). Optional ReadyLIFT SST3000 Performance Rear Shocks (93-3411R) are available separately. This kit is for Single Rear Wheel Only and not suitable for trucks with factory TOP overload springs (camper package). 2011-2019 GM HD trucks require the use of ReadyLIFT 66-7822B Heavy Duty Torsion Key Unloading Tool.
