Performer IAS Series Rear Shocks
Performer IAS Monotube Rear Shock Absorber
  • Inertia-Activated Valve Adjusts Damping to the Road
  • High Pressure Monotube, Gas Charged
  • Polyurethane Bushings, Nitro-Steel Piston Rod
  • Red Powder Coated with Black Boot
  • Sold Individually

    The IAS valve is the reason these behave differently than a conventional shock. On smooth pavement the valve closes and damping firms up, which controls body roll through a corner. Hit a bump or a pothole and it opens, letting the wheel follow the surface instead of jarring the chassis. The monotube design also resists the oil foaming that fades a twin-tube shock when it gets hot.

    Edelbrock 34054 Performer IAS Shock Details:

    • Rear position monotube shock absorber, gas charged.
    • Patented inertia-activated valve that adjusts damping instantly with terrain.
    • Polyurethane bushings and nitro-steel piston rod with heavy duty welds.
    • Red powder coated body with a black protective boot.
    • Sold individually, so order two for a complete axle. Verify the application by vehicle before ordering.
    • A truly unique gas shock.

      Edelbrock's Performer/Classic IAS shocks feature the patented Inertia Active System. This exclusive Edelbrock shock design switches instantly between a soft and a firm circuit for superior handling and a smooth ride. Because it has the ability to switch between circuits almost instantaneously, total control over road surface irregularities is unparalleled with no compromise in handling as in conventional shock designs. Edelbrock Performer/Classic IAS Shocks for GM Cars are Sold individually.

      Performer IAS Shocks were first shocks to include the Inertia Active System. They have a distinctive red powder-coated finish. Classic IAS Shocks include same features as the Performer IAS line but with a gunmetal gray powder coated finish and classic Edelbrock logo.
