Vehicle Fitment: 2011-2019 Duramax 2500HD/3500HD
ReadyLIFT Suspension Inc. is excited to offer our popular 3.5″ SST Lift Kit for 2011-2019 Chevy and GMC 2500HD truck with our all-new heavy-duty Xtreme-Duty upper control arms. This is a premium lift solution that won’t break the bank nor permanently modify your truck. This is a true bolt-on Lift kit with the premium benefit of including our new ultra heavy-duty control arms! The 69-3513 SST Lift Kit by ReadyLIFT will lift the front of your new HD truck a maximum of 3.5 inches! This awesome SST Lift Kit for 2011-19 GM HD trucks includes a pair of tough heavy-duty fabricated steel upper control arms with 1-ton ball joints and maintenance-free TCT pivot bushings. This kit is engineered to match the strength of your truck. 2011-2019 2500HD-specific lift-oriented ReadyLIFT forged torsion keys provide an adjustable lift while maintaining the factory ride. These super strong forged torsion keys are stronger than stock with the same design and features an indexing that is unique to this kit! The 69-3513 Lift Kit also includes CNC-machined differential drop spacers which lowers the differential and puts the front CV axles into safe factory angle on 4WD trucks. 2WD trucks will not use the diff spacers. To lift the rear of your new Chevy Silverado 2500HD truck, the ReadyLIFT SST Lift Kit includes OEM style 1.0″ cast iron rear lift blocks complete with new u-bolts and hardware. A Tow Package version of this kit is also available with a taller 2.0″ rear lift block (69-3514). This kit includes SST3000 Shocks. Also included with this kit are new super strong tie-rod end assemblies to replace the weak factory versions. For the longest time, GM tie rod assemblies have been a weak link on all GM trucks. These heavy duty steering assemblies install easily and incredibly stronger than the OEM units. You won’t find this kind of attention to detail with any other lift kit for the new GM HD trucks! This great combination gives the new GM HD trucks a great raised stance using super strong components and allows for up to a 34″ tall tire. NOTE: Single Rear Wheel Only. NOTE: Not for use on trucks equipped with factory TOP overload spring commonly referred to as a camper package. NOTE: Lift height must not exceed 27.25″ when measured from the center of the wheel to the fender lip above the 12 o’clock position for 4WD and 28″ for 2WD vehicles.
Tire Fitment:
34″ Maximum tire diameter
34×11.50 for no rub on a 9″ wide wheel with +12 offset
18″ – 295/70R18
20″ – 275/65R20
22″ – 285/55R22
Tire Size Note: ReadyLIFT wheel and tire fitment recommendations are typically based on Wheel Pros wheels and Nitto tires. Due to product differences among tire manufacturers, tire specifications and dimensions including, but limited to, overall diameter, rolling diameter, tread width, aspect ratio, lug pattern, sidewall construction and inflation pressure, will vary meaningfully by tire and wheel manufacturer. Every tire and wheel combination should be test fit prior to installation. Consult your local installer to learn more about the right tire fitment for your application.
Ride Quality Note: When lifting a vehicle and installing aftermarket wheels and tires, a tire manufacturer’s construction and material quality can alter vehicle ride quality. When increasing a vehicle wheel and tire size, most larger aftermarket truck and SUV tires are 10-ply (or more) E tires compared to typical OEM 6-ply C tires. This more rigid sidewall construction increases the perception of suspension stiffness often described as ride harshness. The ride, handling, traction, noise, fuel economy, and wear differences between All-Season, All-Terrain, Mud-Terrain, or Trail-Terrain type tires can be significant. Please take into account tire and wheel choice will generally have a meaningful impact on the ride & handling experience.
