Adjustable Shocks.

The GSB2 is a steel mono-tube, adjustable gas shock absorber.  It's available in 7" and 9" stroke and any possible valving.  It has a large built-on gas reservoir. This increases the volume of gas the shock will hold, which lowers the unwanted increase in rod pressure that comes with stroke. It also has a base valve that allows the shock to be effectively operated from zero to 300 PSI gauge pressure.

  • Some cars run a shock in front of the left rear to control the motion on acceleration and braking like a GS194-0 or GS195-0 for Sweeping corner tracks and GS196-0 or a GS198-3 for tighter corner tracks. And on slick tracks when hunting for more traction some cars use a dummy shock GS190. Also available in G1 series. Adjust your gas pressure accordingly any where from zero to 300 psi
