The Cognito Motorsports 12-Inch Elite Lift Kit with Elka 2.5 Reservoir Shocks is a complete suspension system engineered for 2011-2019 Silverado/Sierra 2500/3500 2WD/4WD trucks. This comprehensive kit delivers 12 inches of front lift and 9 inches of rear lift while maintaining superior ride quality through corrected CV joint angles and optimized droop travel. All Cognito components are engineered, manufactured, and assembled in the USA.
SM Series Upper Control Arms: The kit features Ball Joint SM Series Upper Control Arms with boxed sheet metal construction, welded and powder coated in semi-gloss black. Pre-installed maintenance-free ball joints and pivot bushings correct ball joint angles for lifted applications while improving allowable droop travel for enhanced ride quality and performance.
Patented Pitman Idler Arm Support Kit (PISK): Addresses the inherent wear problems in GM steering systems by replacing problematic factory components. The innovative, patented design provides additional support to the pitman and idler arms, eliminating forward and rearward center-link movement for improved steering stability and longevity.
Elka 2.5 Reservoir Shocks: Premium adjustable shocks allow precise fine-tuning of high and low-speed compression damping to adapt your suspension for specific driving styles and terrain conditions. The external reservoir increases oil volume for cooler operating temperatures, delivering better performance and consistency under demanding conditions.
Deaver Leaf Spring System: Complete OEM spring replacement featuring an arched design for 4 inches of rear lift over stock height. Constructed from high-quality spring steel with a higher leaf count and thinner leaf material for a more compliant, comfortable ride without sacrificing load capacity.
