The Cognito 4" Elite Lift Kit with Elka 2.5 Reservoir Shocks is designed for truck owners who demand maximum suspension performance, ride quality, and durability. It delivers a true 4-inch lift while significantly improving handling, stability, and off-road capability.
Built from premium components engineered and manufactured in the USA, this system offers exceptional strength and long-term reliability. The design focuses on optimizing suspension geometry, increasing wheel travel, and maintaining proper droop, making it ideal for towing, heavy-duty use, and aggressive off-road driving.
Additional features include Elka 2.5 remote reservoir shocks with dual-speed compression adjustability, Cognito SM Series upper control arms, and a Pitman & Idler Arm Support Kit. These components work together to reduce vibration, improve ride comfort, and deliver consistent damping performance across varying terrain.
Engineered with vehicle-specific fitment, this system is available for Silverado and Sierra 2500HD/3500HD platforms across multiple model years.
Installation is typically a bolt-on process, though moderate to advanced mechanical experience is recommended due to the scope of suspension modifications.
Whether you're upgrading for off-road performance, towing capability, or a more aggressive stance, this product delivers elite-level suspension performance without compromise. Now Available at LEER!
