The GSB3 is a mono - tube double adjustable base valve it's available in  7" - and 9" stroke and any possible valving or split valving.

The GSB3 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.


The GSB3 is completely rebuildable - revalvable.


  • The GSB3 has the largest true rebound and compression range of adjustments. 3 to 8 on Rebound and Compression is standard, Also available in other ranges. Both adjustments are thru the rod.

  • Large 48mm bore for maximum control and reduction of rod pressure buildup.

  • Largest 75mm built on gas reservoir.

  • Positive stainless steel no-drag scraper to keep any dirt and debris out.

  • Hollow chrome-moly shaft.
  • Low friction Teflon lined self lubricating 1/2 inch bearing on both ends.

  • Has a base valve that allows the shock to be effectively operated from zero to 300 PSI gauge pressure.
  • Double checked  low-speed valving design.
  • Completely independent rebound and compression adjustment.

  • We highly recommend that you check with your chassis builder for their latest  recommendations as technology changes very frequently.

  • 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.
