The Cognito 7" Premier Lift Kit with Elka 2.5 Reservoir 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 system. It delivers substantial lift height while maintaining excellent drivability and towing stability.
Built from premium USA-engineered components, this system is designed to maintain proper steering geometry, suspension alignment, and corrected CV joint angles. The lift kit focuses on preserving adequate droop travel and improving ride comfort across highway driving, towing, and demanding off-road terrain.
Additional features include Elka 2.5 compression-adjustable remote reservoir shocks, Cognito SM Series upper control arms, stainless extended brake lines, HD sway bar components, and heavy-duty rear block and U-bolt kits. Together, these components improve steering response, suspension articulation, and damping consistency 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 is approximately 16 hours.
Whether you're upgrading for larger tires, towing stability, or serious off-road performance, this product delivers premium suspension capability and ride refinement without compromise. Now Available at LEER!
