The Rancho 4" lift kit for the Chevy Silverado and GMC Sierra includes 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. 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. Rear coil springs included. No drivetrain or exhaust modification required.
