Non Adjustable Base Valve Shock Absorbers

The GSB1 is a mono-tube, non-adjustable gas shock absorber.  It's available in 7"  and 9" stroke and any possible valving or split valving.  It has 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.



  • 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.
  • The finest high quality, high viscosity index, 100% Synthetic Shock absorber oil virtually 0 thermal expansion.
  • 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.


  • Much more traction than standard shocks especially in slick conditions.

  • More driver feel which results in better feedback to adjust to ever changing track conditions.

  • The GSB1 is completely rebuildable, and revalvable.

  • 3600 Coil Over Kit for GS0,GD,GS1,GS2,GS3,GSB1,GSB2 and GSB3 Series Shocks is required for coil over applications with 2 1/2 springs.

  • 3675 Coil Over Kit for 5" Springs for GS0,GD,GS1,GS2,GS3,GSB1,GSB2 and GSB3 Series shocks.
  • 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 GSB194-0 or GSB195-0 for Sweeping corner tracks and GSB196-0 or a GSB198-3 for tighter corner tracks. And on slick tracks when hunting for more traction some cars use a dummy shock GSB190. Also available in GS0 and GS1 series. Adjust your gas pressure accordingly any where from zero to 300 psi.
