The Rancho 4" suspension lift kit for the Avalanche, Suburban, Tahoe and Yukon features a one-piece sub-frame to provide maximum ground clearance and superior strength to the vehicle. Precisely relocating the lower control arms and differential, the sub-frame is engineered to ensure that both suspension and drivetrain geometry is calibrated to the optimal setting. Front differential drop brackets correct pinion angle for minimized driveline vibration. High clearance aft braces and rear coil springs included. Steering integrity is uncompromised by maintaining the stock location of the factory rack and pinion steering. This, along with the heavy duty CNC extended cast steering knuckles, maintains optimal steering geometry and results in a faster, easier installation.
Front struts and rear shocks are required and sold separately. Browse for Rancho strut and shock options available in RS5000, RS7000MT and RS9000XL
