The Cognito Motorsports 12-Inch Performance Lift Kit delivers a complete suspension transformation for 2011-2019 Silverado/Sierra 2500/3500 trucks in both 2WD and 4WD configurations. This comprehensive system combines premium Cognito components with Fox 2.0 Performance Series Remote Reservoir shocks to provide superior ride quality, corrected geometry, and capability for aggressive tire fitments.
Front Suspension Components:
The kit includes SM Series Ball Joint Upper Control Arms featuring boxed sheet metal construction with CNC robot welding and semi-gloss black powder coating. These arms correct ball joint angles for lifted applications while improving droop travel for enhanced ride quality. Each arm comes with ball joints, crush sleeves, and polyurethane bushings installed.
Cognito's patented Pitman and Idler Arm Support Kit (PISK) addresses the chronic wear issues found in GM steering systems by providing additional support that eliminates forward and rearward center-link movement. This innovation significantly extends component life and maintains steering precision.
The HD front sway bar measures 1.5 inches in diameter and is manufactured from heat-treated, hot-formed 4140 chromoly steel. This upgraded bar reduces body roll for improved vehicle control and traction, and includes oversized clamps with polyurethane bushings.
Fox 2.0 Performance Series Shocks:
Fox 2.0 Performance Series Remote Reservoir shocks feature extruded aluminum bodies for maximum heat dissipation and rust-resistant construction. The remote reservoir design eliminates oil aeration, allowing the factory-tuned precision valving to deliver consistent performance. These shocks provide comfortable on-road manners with predictable off-road handling in demanding conditions.
Rear Suspension:
The Deaver leaf spring pack completely replaces the OEM springs with an arched design that delivers 4 inches of lift. Constructed from high-quality spring steel with increased leaf count and optimized leaf thickness, these springs provide excellent load capacity while maintaining a compliant ride. The included Cognito 5-inch block and heavy-duty zinc-plated U-bolt kit adds additional rear lift for a level stance.
