- 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.
- 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.
- Can be used as a coil-over shock with 106-20135D coil-over hardware kit (purchase separate).
- Lightweight aluminum construction also helps dissipate heat
- Rebound settings are adjusted via a shaft-mounted knob with 32 clicks
- Compression settings are adjusted via a body-mounted know with 32 clicks
- Smooth, Ultra Low Friction rod guide
- Low resistance allows internals to function to their fullest potential
- Almost no "stiction" to interfere with putting the power down
- Coil-over Ready w/ purchase of kit 106-20135D
