Cognito 6" Performance Lift Kit w/Fox PSRR 2.0 Shocks

 

The Cognito 6" Performance Lift Kit with FOX PSRR 2.0 Shocks is designed for Silverado and Sierra 2500HD/3500HD owners looking for a premium suspension upgrade that delivers improved ride quality, increased clearance, and enhanced off-road capability. It provides a true 6-inch lifted stance while maintaining predictable handling and towing stability.

Built from premium USA-engineered components, this system is designed to maintain proper suspension geometry, steering alignment, and driveline angles. The non-torsion bar drop design improves CV joint angles while preserving droop travel for a smoother and more controlled ride both on and off-road.

Additional features include FOX 2.0 remote reservoir shocks, SM Series boxed upper control arms, Cognito’s patented Pitman & Idler Arm Support Kit (PISK), and heavy-duty rear lift blocks with zinc-plated U-bolts. Together, these components improve front-end rigidity, steering response, suspension articulation, and damping consistency across demanding terrain.

Engineered specifically for 2011–2019 Silverado and Sierra 2500HD/3500HD 2WD and 4WD applications, the system integrates seamlessly with factory suspension systems using vehicle-specific components.

Installation is typically a bolt-on process, though moderate to advanced mechanical experience is recommended due to the scope of suspension modifications. Estimated DIY installation time is approximately 13 hours.

Whether you're upgrading for larger tire fitment, towing stability, or serious off-road capability, this product delivers dependable suspension performance and premium ride quality. Now Available at LEER!
