Description
Lifted Stance. Add a commanding, lifted off-road stance to your 2011-2019 2500 HD GMC Sierra by upgrading to a ReadyLIFT SST Suspension Lift Kit that includes SST3000 Shocks. With 3.50 inches of lift front and 2 inch rear, this kit can accommodate tires up to 34-inches in size allowing you to conquer any trail. This ReadyLIFT SST Suspension Lift Kit features extreme-duty upper control arms, forged torsion leveling keys, heavy duty tie rod assemblies, differential drop spacers as well as rear lift blocks. What’s more, the included SST3000 Series Shocks will provide a highly comfortable ride, even across the roughest terrain.
Extreme-Duty Upper Control Arms. ReadyLIFT fabricates their Control Arms from laser cut and CNC bent .125 4130 chromoly plate steel using a tab and slot boxed design to increase overall strength and durability. The 1-ton spring loaded HD series ball joints help to maintain a factory driving experience while taking a beating. Frame side pivots feature ReadyLIFT's new maintenance free and self lubricating Terrain Control Technology (TCT) bushings. These new bushings include a new "free float" inner bushing with "side biter" washers to aid in maintaining alignment settings while eliminating friction which is the most common cause of traditional bushing failure.
SST3000 Series Shocks. Manufactured using a nitrogen charged twin-tube design, the included ReadyLIFT SST3000 Shocks feature a 5/8-inch hard chrome plated shaft. The two-stage sealing system effectively keeps dirt out and oil in for quicker rebound and smoother compression during the shock cycle. ReadyLIFT SST3000 Shocks feature an outer steel housing that is completed in durable black finish for impressive good looks.
Forged Torsion Leveling Keys. Vehicle specific lift-oriented ReadyLIFT forged torsion keys provide an adjustable lift while maintaining factory ride quality. These super strong forged torsion keys are much stronger than the stock units with the same design and feature an indexing that is unique to this ReadyLIFT kit.
Rear Lift Blocks. Rear lift is obtained with the use of 2-inch blocks and u bolts. These OE-style lift blocks are fabricated from cast iron for superior strength. The included longer u-bolts and fasteners allow for a straight forward installation.
Differential Drop Spacers. This Lift Kit also includes CNC-machined differential drop spacers which lowers the differential and puts the front CV axles into a safe factory angle on 4WD trucks. Please note that 2WD models will not use the differential drop spacers.
Heavy Duty Tie Rod Assemblies. Also included with this ReadyLIFT 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.
Bolt-on Installation. ReadyLIFT designed their SST Suspension Lift Kit to be a straight forward bolt-on install with no cutting or welding required. With all the necessary hardware included, this Lift Kit can be installed in about 8 hours time - professional installation is recommended. Please note that an alignment is required after installation.
Application. This ReadyLIFT 3.50-Inch Front / 2-Inch Rear Xtreme-Duty Fabricated A-Arm SST Suspension Lift Kit with SST3000 Shocks is designed for 2011-2019 GMC Sierra 2500 HD models.
