Details
We have bundled everything you need in a lift kit for your Silverado/Sierra 2500/3500 2WD/4WD with high quality Cognito components. There is no guesswork. Cognito components are engineered, manufactured, and assembled in the USA. 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 boxed sheet metal arms are welded, and powder coated semi-gloss black. Pre-installed maintenance free ball joints and pivot bushings are included. The Cognito Pitman and Idler Arm Support Kit: 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. The Cognito 2-inch Block and U-Bolt Kit includes 2-inch tall powder coated semi-gloss black cast steel blocks and heavy-duty zinc plated U-bolts The Elka 2.5 shocks feature Dual Speed Compression adjustment and provide better attenuation of vibration, leading to major noise reduction in the cabin (much less squeak and rattle), damping characteristics optimized for each truck and setup, providing a smoother ride. Increased comfort in both on road and off-road conditions, especially over washboard and square-edge impacts, more stable and more predictable handling, reduced front-end diving when cornering or braking reduced rear-end bucking and lifting, and increased damping and spring rate for better handling when towing or loading truck.
