The Straightline TSS-04 Spring is a clutch spring built for snowmobile applications, designed to work with weights ranging from 160 to 260 lbs. That range lets you dial in the spring rate to match your machine's setup rather than settling for a one-size-fits-all component.

It comes in a black and white finish and measures 5 × 3 × 3 in, weighing 1 lb.
