This Straightline Performance Billet Adjustable Weight Kit gives you a set of three precision-machined clutch weights that tune from 64 to 80 grams right out of the box, with an optional tungsten washer kit extending the range to 88.6 grams. The set-screw adjustment system lets you change weight mass without buying multiple weight sets, so you can compensate for elevation, modifications, or riding style on the fly.

Each weight is heat-treated to the ideal hardness and finished with yellow zinc plating for corrosion resistance, making the kit suitable for trail, mountain, crossover, and racing snowmobiles. The package includes the three weights, tuning hardware, adjustment components, and complete tuning instructions.
