ReadyLIFT Suspension Inc. presents the 3.5" SST Lift Kit for 2011-2019 Chevy and GMC 2500HD trucks featuring new heavy-duty Xtreme-Duty upper control arms. This affordable bolt-on lift kit includes ultra-heavy-duty control arms making it a premium solution without permanent modifications. The 69-3514 SST Lift Kit elevates the front of these HD trucks by up to 3.5 inches. It incorporates heavy-duty fabricated steel upper control arms with 1-ton ball joints and maintenance-free TCT pivot bushings engineered to complement the truck's strength. Additionally the kit contains 2011-2019 2500HD-specific ReadyLIFT forged torsion keys for adjustable lift while maintaining factory ride quality. These forged torsion keys are more robust than stock and uniquely indexed for this kit. CNC-machined differential drop spacers are included to adjust the front CV axles angle on 4WD trucks while 2WD models don't require these spacers. To elevate the rear the kit features OEM style 2.0" cast iron rear lift blocks u-bolts and hardware. SST3000 Shocks are also included. Further enhancing the kit are new stronger tie-rod end assemblies replacing weaker factory versions and ensuring greater durability. This lift kit provides a raised stance using robust components and accommodates up to a 34" tire. It's suitable for Single Rear Wheel models only and not for trucks with factory TOP overload spring (camper package). Note the maximum lift height: 27.25" from the wheel center to the fender lip for 4WD and 28" for 2WD vehicles.
