The Cognito 7" Performance Lift Kit with FOX PSRR 2.0 Shocks is designed for Silverado and Sierra 2500HD/3500HD owners looking for premium ride quality, improved suspension geometry, and aggressive off-road capability in a complete engineered suspension package. It delivers substantial lift height while maintaining excellent drivability, towing stability, and suspension performance.
Built from premium USA-engineered components, this system is designed to maintain proper steering geometry, corrected CV joint angles, and adequate droop travel for smoother operation both on-road and off-road. The non-torsion bar drop design helps preserve suspension articulation while improving handling stability under load.
Additional features include FOX 2.0 remote reservoir shocks, Cognito SM Series upper control arms, SM Series compression struts, stainless extended brake lines, and heavy-duty rear block and U-bolt kits. These components work together to reduce suspension harshness, improve steering response, and provide consistent damping across varying terrain 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 moderate to advanced mechanical experience is recommended due to the scope of suspension modifications. Estimated DIY installation time ranges from approximately 13–16 hours depending on application.
Whether you're upgrading for larger tires, towing stability, or enhanced off-road performance, this product delivers dependable suspension capability and premium ride quality. Now Available at LEER!
