Chevrolet Silverado 2500HD Suspension Lift Kit - Cognito - Elka 2.5 RR Shocks, SM Series Ball Joint Upper Control Arms, Cognito Block and U-Bolt Kit (2020–2024). A proven combo to upgrade ride quality and steering on your 2500HD.

Elka 2.5 remote-reservoir shocks with Dual Speed Compression let you dial slow and fast compression for a smoother, quieter ride on pavement and dirt. Tuning reduces vibration, brake dive, and rear bucking, with better control when towing or hauling. Cognito SM Series ball-joint UCAs correct ball-joint angle on lifted or leveled setups and add droop travel. Powder-coated semi-gloss black Cognito blocks with heavy-duty zinc-plated U-bolts add durable rear support. Built for 2020–2024 Silverado 2500HD; Cognito components are engineered and assembled in the USA.
