Description: The extreme shock. Edelbrock Performer IAS Twin-Tube shocks use a patented inertia-activated valve that instantly adjusts to driving conditions. It's simple: 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 shock softer and more responsive. Your wheels will follow the contour of the driving surface for a smoother off-road ride. The shocks use polyurethane bushings for added responsiveness, and the high-pressure, cellular-gas design features an expanded 60mm outer tube for additional fluid capacity. The twin-tube construction protects the inner tube from damage in extreme conditions while dissipating heat more effectively. Other features include nitro-steel piston rods, heavy-duty welds, and an attractive red powdercoat finish. (minimize)
