Steel Small-Body Shocks 70 Series
Steel Monotube Stock-Mount Shocks 27A Series IMCA-Legal Similar to the 27 series, but the gas pressure tunabil- ity has been disabled to meet IMCA rules. Stock-mount, IMCA-legal shock absorbers include a damping curve that allows for complete suspension control at low shaft speeds without creating extreme forces at high shaft velocities. Racer rebuildable and revalvable, electroless nickel-plated body shocks are made in the USA, 100% dyno tested, and serialized.
Twin-tube, 1-5/8" O.D. shock bodies house aluminum pistons and base valves, 1/2" centerless ground, hard chrome piston rods, and replaceable, 1/2" I.D. bearings. Shocks may be rebuilt and re-valved, and can be run upside down to reduce unsprung weight with no change in rate.
