Adjustable billet coil over shock throttle return spring kit for a Quadrajet carburetor. Once this kit is installed, it allows the user to adjust the tension in the throttle return spring without having to change the actual spring. Simply spin the adjuster ring on the threaded shock body to add or remove preload on the shock in the same way you would on the coil over of your suspension.  


All the bracketry is made of 6061 billet aluminum and is available in either a clear or black  anodized finish. The shocks are also billet aluminum and can be ordered in 5 colors: clear, black, red, blue or purple.
