We have bundled everything you need in a leveling kit for your Silverado/Sierra 2500/3500 2WD/4WD with high quality Cognito components. There is no guesswork.

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 CNC robot welded and powder coated semi-gloss black. Heavy duty ball joints are included as well as new crush sleeves and polyurethane bushings. The Cognito 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 pitman and idler arms, which eliminate the forward and rearward movement of the center-link. King's new line of Original equipment manufacturer, (OEM), shock upgrade kits provide a bolt on suspension system that elevates your on and off-road performance to unmatched levels.

Each kit has been subjected to punishing real world testing to develop the optimal damping curves and spring rates for your vehicle. Built with the same quality of materials and precise tolerances found on our high-end race shocks our OEM upgrade kits enable you to experience the famous King ride quality on your daily driver or prerunner.

Built with race winning design features our kits come complete and provide simple 100 percent bolt on installation with no cutting or welding done to your vehicle. Our front kits provide an adjustable ride height and up to a 25 percent increase in wheel travel.

Rear kits typically allow a 15 percent travel increase. Large 2.5-inch diameter shock bodies and external reservoirs dramatically increase fluid capacity and heat dissipation to provide sustained damping performance even under the most punishing conditions. Our OEM upgrade shocks feature the same serviceable design that allows for valve adjustments with simple hand tools just like our race shocks.
