These Straightline Performance clutch weights are built for the Arctic Cat ADAPT system, letting you dial in clutch engagement and shift points across trail, mountain, race, turbo, and nitrous builds. The billet construction is CNC machined, heat treated, and finished with a yellow zinc coating, then post-bake annealed for dimensional stability.

Adjustable from 64 to 100 grams across four areas, they come with set screws, bolts, washers, and tungsten inserts so you can fine-tune RPM without buying multiple weight sets.
