We have bundled everything you need in a lift kit for your GM 2500/3500 with high quality Cognito components. There is no guesswork. Cognito components are engineered, manufactured, and assembled in the USA. The Cognito 12-Inch Elite Lift Kit with 2.5 Elka Reservoir Shocks is designed and engineered to offer superior ride quality and corrected CV joint angles. 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 Pitman 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 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 Elka 2.5 Reservoir shock allows precise fine-tuning of the high-& low-speed compression damping so you can adapt the suspension for your specific driving style and terrain conditions without compromise. It also features an external reservoir with increased oil volume for cooler operating temperature, providing better performance and consistency. The Deaver spring is a complete replacement of the OEM spring, and is arched for 4-Inch over stock rear lift height while maintaining an excellent ride quality via being made from high quality spring steel, a higher leaf count with thinner leaf material for a more compliant ride. The Cognito 5-inch Block and U-Bolt Kit includes 5-inch tall powder coated semi-gloss black steel blocks and heavy-duty zinc plated U-bolts.
