One of the most overlooked modifcations for the aging S-chassis is replacing worn subframe bushings. A large amount of suspension dynamics is compromised when energy is transferred to the shifting subframe instead of being directed towards the dampers Replacing tired and old rubber bushings with these solid anodized aluminum bushings will result in better suspension feel and response that a driver yearns for. Raises subframe just under a half inch correcting suspension geometry on lowered vehicles.
