We have bundled everything you need in a leveling kit for your Silverado/Sierra 2500/3500 2WD/4WD with high quality Cognito components and Elka shocks. There is no guesswork. Cognito components are engineered, manufactured and assembled in the USA. This kit includes the Cognito Ball Joint SM Series Upper Control Arm Kit, Torsion Bar Adjuster Keys, Cognito Pitman and Idler Arm Support Kit, front and rear Elka Reservoir shocks. The Cognito Ball Joint SM Series Upper Control Arms add style, function and performance to your vehicle by correcting the ball joint angle for lifted and leveled applications and improving the allowable droop travel for a better ride quality. The control arm kit features boxed sheet metal arms that are welded, and powder coated semi-gloss black. Pre-installed maintenance free ball joints and pivot bushings are included. The Cognito Ball Joint SM Series Upper Control Arms provide ample droop travel that is required for optimal ride quality and all suspension components to last and work properly. Cognito Torsion Bar Keys levels the front with the rear of the truck. Their forged construction makes them practically indestructible and they bolt in for easy installation. Pitman and Idler arms have been an inherent wear problem within the steering systems of Chevy and GMC trucks and SUVs for decades. The Cognito PISK (Pitman and Idler Arm Support Kit) replace the problem components that plague factory and aftermarket steering systems on several models and years of GM trucks and SUVs. These improvements are accomplished through application of Cognito's innovative, patented design, by providing additional support to the vehicle's pitman and idler arms, which eliminate the forward and rearward movement of the center-link.
