Warning - The chart below is a general guide only. We highly recommend you measure your chassis for proper length and mount points before ordering.

How to Choose Shock Length (GIF)

  • '70-'81 Camaro*  -  Part # 1063875R2
  • '73 Nova Non - H.D. Rear  -  Part # 1063875F (same as '93-'02 Camaro FRONT - mounting point mods may be needed)
  • Shock also fits all Buick, Oldsmobile, and Pontiac equivalents.

(*) May need to "slot" tie bar mount.


  1. The rebound adjustment is the most critical in tuning a drag racing set-up. This adjustment allows the tuner to dial in the "un-loading action" of the chassis and keep the tires planted during the critical first 60' down the track.
  2. Double adjustable shocks are the ultimate tool in the chassis tuner's arsenal. The double adjustments of both compression and rebound dampening are completely independent - changing the setting of one has no effect on the setting of the other.
  3. Can be used as a coil-over shock with 106-20135D coil-over hardware kit (purchase separate).
Some parts are not legal for use in California or other states with similar laws/regulations
