2011-2015 GMC Sierra Denali 2500HD/3500HD SST Lift Kit

ReadyLIFT® Suspension Inc. is excited to offer new 2011-2015 Chevy and GMC 2500HD and 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 new Stage 1 69-3411 SST Lift Kit by ReadyLIFT® will lift the front of your new HD truck a maximum of 4 inches!

This awesome new SST Lift Kit for new GMC/Chevy HD trucks includes a pair of tough heavy-duty tubular steel upper control arms engineered to match the strength of your truck. 2011-UP HD-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 a indexing that is unique to this kit!

The Stage 1 69-3411 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 us the diff spacers.

To lift the rear of your new GMC Sierra Denali or Silverado 2500/3500 HD 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.

(Optional ReadyLIFT SST9000 Performance Rear Shocks 99-3411R also available - sold separately) .

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 inch tall tire.

NOTE: Requires the use of longer front shocks. Shocks not included with Stage 1 kit 69-3411.
Recommend ReadyLIFT SST9000 Performance Shocks 99-3414F (Front Shocks) designed specifically for this lift kit.

NOTE: Single Rear Wheel Only
Not for use on trucks equipped with factory TOP overload spring commonly referred to as a camper package.
