Polaris clutch springs are designed specifically for Polaris snowmobile clutching systems. The springs are used to enhance the performance of a snowmobile. Polaris sells primary clutch springs and secondary clutch springs. The primary clutch springs are color coded to represent compression rates based on the number of pounds of force needed to compress the spring 2.5 inches and 1.19 inches. The secondary clutch springs are color coded to rate degrees in softness, from a soft 1 to a firm 7.
