This Is The RPM Quick Adjustable Spring Clip Associated/Kyosho rpm 70222

These are made of injection molded black nylon. This is a quick system of
adjusting the shock spring load. These replace the shock collars and are
a superior upgrade to adjust the springs on shocks. Just add or remove clips
and the changes are exact. The set comes with 16 spacer clips, four each of
1/16, 1/8, 3/16, and 1/4. This is enough to convert 4 shocks. They will work
with any ASSOCIATED shocks or KYOSHO gold or platinum shocks
