Description: The world's smartest shock. Edelbrock Performer IAS monotube shocks use a patented inertia-activated valve that instantly adjusts to driving conditions. It's simple enough: On smooth terrain, the valve closes to give you a firm ride, excellent cornering, and reduced body sway. Under rough conditions, the valve opens to make the shocks softer and more responsive. So your wheels follow the contour of the driving surface, for a smoother off-road ride. These shocks use polyurethane bushings for added responsiveness, and their high-pressure monotube design eliminates oil foaming and dissipates heat more effectively. Other features include nitro-steel piston rods, heavy-duty welds, and an attractive red powdercoated finish. (minimize)
