These adjustable weight pins are hollow threaded pins that allow you to use a combination of set screws seated down the center of the pin to vary the weight of the pin. This effectively allows you to change the weight of your pins, resulting in a change of running RPM. Adding more weight results in lower RPM, less weight will result in higher RPM. For all Ski-Doo snowmobiles with TRA 2, TRA3, or TRA5 primary clutches. Sold per set.
