This Straightline Performance clutch kit is built specifically for the Arctic Cat Catalyst 858, calibrated for trail riding at 0–3000 ft. It pairs machined billet ADAPT clutch weights with a custom helix cut to the 858's power curve, so shift response and backshift stay consistent through the RPM range.

Two clutch springs handle engagement and backshift, and the fully adjustable weights let you dial in the shift curve to your machine and riding style. The springs carry a lifetime warranty.
