The Cognito 210-P1035 12" Performance Lift Kit With Fox 2.0 PSRR Shocks from SDS has everything you need in a lift kit for your GM Silverado/Sierra 2500HD/3500HD. Cognito engineered this lift kit to provide superior ride quality and corrected CV joint angles. The Cognito SM Series Upper Control Arms in this kit add style, function, and performance to your vehicle. These control arms feature corrected Ball Joint angles and improved allowable droop travel for a better ride quality. The Cognito PISK (Pitman and Idler Arm Support Kit) provides extra support to the vehicle's pitman and idler arms, which eliminates the forward and rearward movement of the center-link.

The Deaver spring is a complete replacement of the factory leaf springs. These leaf springs are arched for 4" over stock rear lift height. The high-quality spring steel and higher leaf count with thinner leaf material provide a smooth ride. The Cognito 5" Block and U-Bolt Kit includes 5" tall powder coated semi-gloss black steel blocks and heavy-duty zinc plated U-bolts. Cognito includes Fox 2.0 Performance Series Remote Reservoir shocks with this kit to further enhance ride quality. The Fox 2.0 Performance Series front shocks are rust resistant and have a metal impact extruded aluminum body to increase cooling capacity. These shocks deliver a comfortable on-road ride and predictable off-road handling in even the toughest conditions.
