SLP offers custom-built shift weights for Polaris and Comet clutches. These TCP/WMS - designed weights are tuneable by drilling out the available four 1/16" pre-drilled holes for your desired shift RPM, or rate of shift. Weights are fully machined from alloy steel, bushed and hardened for better performance and durability. The weight has an aggressive shift profile and heavy tail for the best performance. Typically clutches can utilize 3 grams heavier Lightning weight than standard weight.

Sold per set of three.
