What's in the Box


These are specifically valved for high horsepower applications. Both small tire and big tire cars can better control the “hit” to the tire with this series of shocks. Don’t “drive thru” your shocks with that big power — choose this series of shocks for the ultimate control off the line. Mount the shock upside-down for easier access to the rebound adjuster.

  • Body Mount:  1/2" I.D. Bearing (1.060" wide)
  • Shaft Mount:  1/2" I.D. Bearing (1.060" wide)
  • Double Adjustable - broad range of adjustment
  • Big Gun Valving - specifically valved for high horsepower applications
  • Shock of choice for Swing Arm Dragsters
  • Great for BIG or SMALL tire door slammers
  • Large piston provides superior launch stability
  • Gas pressure eliminates cavitation and allows shock to recover faster

Includes coil-over kit. Coil spring NOT included.
