Straightline Performance Ski-Doo 600RS Snowcross Race Clutch Kit | 129-137″ Full Race Clutching Package

Description

The Straightline Performance Ski-Doo 600RS Snowcross Race Clutch Kit was developed specifically for competitive snowcross racers demanding every possible advantage on the starting line, through the corners, and across the finish line.

Built around years of race-proven clutch development, this package delivers the acceleration, consistency, and adjustability required at the highest levels of snowcross competition. Designed for Ski-Doo 600RS race sleds equipped with 129-inch and 137-inch tracks, the kit provides a complete primary clutch calibration engineered to maximize power transfer and maintain optimal engine RPM under the demanding conditions of modern snowcross racing.

At the heart of the package is Straightline Performance’s proven adjustable P-Drive weight system. This race-tested design allows precise clutch tuning to match track conditions, rider preference, and changing race-day requirements. Combined with a custom-developed race tuning fin and specially calibrated primary spring, the system delivers aggressive engagement characteristics, explosive holeshot performance, and strong pull throughout the entire powerband.

Unlike many race clutch kits that replace every component, Straightline’s extensive testing has shown the factory Ski-Doo secondary clutch components to be highly effective when properly calibrated. For this reason, the kit utilizes the OEM secondary helix and spring combination while providing racers with proven baseline settings developed through extensive on-track testing. This approach simplifies setup while delivering exceptional performance and consistency.

Whether you’re chasing championships, podium finishes, or faster lap times, the Straightline Performance 600RS Snowcross Race Clutch Kit provides the tuning precision, reliability, and performance required to compete at the highest level.
