Aluminum Threaded Small-Body Shocks
82 Series
Aluminum body, 82 Series shocks are up to 40% lighter than full-size shocks. Deflective disc valving offers increased sen- sitivity in response, control, and consistency. Shocks are fully rebuildable, revalvable, and repairable. Note: Shocks are also available in 8" and 9" strokes.

Sealed Aluminum Threaded Twin-Tube
Shocks - 63 Series
The 63 Series is a sealed, non-rebuildable version of the 62 Series. These are most commonly used in coil-over applica- tions on both dirt and asphalt tracks. The twin-tube design gives excellent feel and grip across all track conditions, but they really shine when there is a lack of grip. Built as a spec shock that could be used at specific tracks or series, the 63 Series can be used in any late model or modified.
Steel Small-Body Shocks - 70 Series Twin-tube, 1-5/8" O.D. shock bodies house aluminum pis- tons 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.
