Description
The primary clutch spring is critical to your M 8000’s engagement characteristics and peak RPM performance. A worn or weak OEM spring forces you to leave power on the table, reducing throttle response and limiting your sled’s potential. SLP’s 40-77 Primary Spring restores crisp engagement and optimized shift points, giving you the controlled acceleration and peak performance your machine demands.
