Product Overview

 

The Cognito 12" Performance Lift Kit with FOX 2.0 PSRR Shocks is designed for Silverado and Sierra 2500HD/3500HD owners who want maximum lift height, aggressive styling, and premium suspension performance in a complete engineered suspension system. It delivers substantial ground clearance while maintaining dependable ride quality, steering stability, and towing capability.

Built from premium USA-engineered components, this system is designed to maintain proper steering geometry, suspension alignment, and corrected CV joint angles. The non-torsion bar drop design preserves adequate droop travel and suspension articulation while improving drivability on-road and off-road.

Additional features include FOX 2.0 Performance Series remote reservoir shocks, SM Series upper control arms, SM Series compression struts, stainless steel braided brake lines, forged torsion bar keys, and a Deaver rear leaf pack with Cognito block and U-bolt system. Together, these components improve suspension damping, reduce harshness, and provide predictable handling across rough terrain and highway driving conditions.

Engineered specifically for Silverado and Sierra 2500HD/3500HD applications, the system integrates seamlessly with factory suspension systems using vehicle-specific components. Available configurations support both 2011–2019 and 2020–2025 GM HD truck platforms.

Installation is typically a bolt-on process, though advanced mechanical experience is recommended due to the scope of suspension modifications. Estimated DIY installation time is approximately 18 hours.

Whether you're upgrading for larger tires, show-truck styling, or serious off-road capability, this product delivers dependable suspension performance and commanding presence without compromise. Now Available at LEER!
