This set of three Straightline Performance billet adjustable clutch weights lets you fine-tune clutch mass from 78 to 93 grams using neodymium magnets, so you can dial in RPM for elevation, modifications, or riding style without buying multiple weight sets. Each weight is precision-machined from billet material, heat-treated for hardness, and finished with yellow zinc plating for corrosion resistance.

The kit includes the three weights, magnet tuning components in 1.3-gram increments, and complete tuning instructions, making it a practical solution for turbocharged and high-horsepower snowmobiles across trail, mountain, crossover, and racing applications.
