ReadyLift 69-3513 3.5"/1" SST Lift Kit With Extreme Duty Control Arms

The ReadyLift 69-3513 3.5"/1" SST Lift Kit With Extreme Duty Control Arms is one of the most rugged 3.5" lift kits available for your 2011-2019 GM Silverado/Sierra 2500HD/3500HD. Readylift takes their premium SST lift kit and combines it with their time-tested fabricated steel control arms. This creates an incredibly strong and reliable package that's been engineered for long-lasting use. 

The SST lift kit includes forged torsion keys which features indexing that is unique to this kit. CNC-machined differential drop spacers provide a safe factory angle for the CV shafts by lowering the front differential. The Readylift 69-3513 includes factory style lift blocks complete with u-bolts, all necessary hardware, and SST300 shocks, providing a 3.5" front lift and 1" rear lift for a level stance.

Featuring CNC-bent .125" chromoly plate steel construction, the Extreme-Duty upper control arms use 1-ton spring loaded HD ball joints that can take a beating from the excessive weight of heavy aftermarket wheels and tires. The frame side pivots features Readylift's proprietary TCT bushings which are self-lubricating. The free-floating bushing design eliminates friction which is the most common reason for traditional bushing failure. 

Readylift addresses the common weak link on GM trucks by including their super strong tie-rod assemblies to replace your factory units. These heavy duty steering assemblies install easily and are incredibly stronger than the OEM tie-rods. You won't find this kind of attention to detail with any other lift kit for the GM HD trucks! This great combination provides a great raised stances using super strong components and allows for up to a 34" tall tire. 

Note: Not for use on trucks equipped with factory top overload springs (camper package) or dually models.
