Built For Strength With Proven Suspension Engineering

The Cognito 12-inch Performance Lift Kit is a complete system built with attention to detail and long-term durability. At the heart of the kit are SM Series upper control arms that correct ball joint angles while improving suspension travel for a smoother ride. Fox 2.0 remote reservoir shocks are included, offering a metal impact-extruded aluminum body that increases cooling capacity while preventing oil aeration, ensuring consistent damping performance. In the rear, a Deaver leaf pack replaces the factory springs with high quality steel and a thinner multi-leaf design, delivering a compliant ride without sacrificing load capacity. To strengthen the steering system, the patented pitman and idler arm support kit eliminates unwanted center-link movement, addressing a common wear point on GM trucks. Forged torsion bar keys, stainless steel braided brake lines, and compression struts round out the front suspension for a complete, reinforced setup. With corrected CV joint angles and maintained droop travel, this lift balances big height with safe, predictable handling. It is designed to handle serious off-road use while keeping your truck stable and dependable on the pavement.
