2011-2019 Duramax 2500HD/3500HD Readylift 3.5″/2″ Lift Kit with SST3000 Shocks

ReadyLIFT Suspension is excited to offer 2011-2019 Chevy and GMC 3500HD truck owners a lift solution that won’t break the bank nor permanently modify your truck. This is a true bolt-on Lift kit! The 69-3522 SST Lift Kit by ReadyLIFT takes our 69-3521 kit one step further by creating a “Tow Package” kit that includes a 2.0″ rear lift block to provide additional rake for towing and hauling. This kit will lift the front of your new HD truck a maximum of 3.5 inches! This kit is for use on 2011-2018 3500HD trucks WITH Single Rear Wheels and Factory Tow Package Leaf Springs OR Dually Rear Wheels.  NOTE:  This kit is not compatible with trucks equipped with top-mounted overload springs. This awesome new SST Lift Kit for new Chevy Silverado 3500HD trucks includes a pair of tough heavy-duty tubular steel upper Control Arms engineered to match the strength of your truck. 2011-2019 3500HD-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 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 3500HD truck, the ReadyLIFT SST Lift Kit includes OEM style 2.0″ cast iron rear lift blocks complete with new U-bolts and hardware. This is our Tow Package version of this kit. This Kit Includes SST3000 Performance 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 2011-2018 GM HD trucks a great raised stance using super strong components and allows for up to a 34-inch tall tire.

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.
