Double Adjustable (Rebound & Compression)

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. By allowing full control over both compression and rebound forces, this shock gives the tuner the ability to fine tune every aspect of chassis movement to provide the ultimate in acceleration control and overall driveability.
