Simple questions with a lot of variables. How long do clutch springs last? I'm sure the type of riding and the age of the springs are factors.


generally speaking...............

Do stiffer rate springs wear out faster than soft springs?

Do aftermarket springs last as long as OEM?

Do primary springs tend to need to be replaced more often than secondary?

Is a "clutched" sled more sensitive to any spring rate changes? My thought is that when you clutch a sled you are trying to get the clutches to shift as fast as possible without over shifting and a slight change in spring rate could make it over shift. A stock clutch set up, I think, would be more forgiving to the spring rate.

How often do you guys that race have to replace springs?
 

No, stiffer springs dont wear faster then softer ones, they all wear with simply time and mileage. The clutch springs are something thats taken for granted, they are a very abused part, they go thru thoudsands of cycles during a ride, they are constantly subjected to heat cycling and they do take a set after a while. You will usually notice a drop in rpm or sometimes the spring will just break a coil. Its advisable to change them out every couple years, even with the sled sitting there off theres a load on the spring, so it will take a set, or lose pressure after time.
