Many of the newer Skidoo 4 stroke models use a torsion style secondary spring. We have some options for those who do clutch tuning.
The updated OEM spring (2014 short track, OEM# 417 127 344*) we received was, like this one, a variable diameter. We tested that spring at our load test height to be 42/66. These new springs are made from a slightly heavier wire diameter, and from high quality chrome silicon HT wire ( high tensile strength alloy) and built to our specs.
Black with Yellow/Green is a similar design to stock but with .200” wire.
Black with Yellow/Red is slightly heavier than the older "beige" OEM spring.This spring uses .207” wire.
You should be aware that because they are torsion springs, that there is more to consider than just compression loads. These springs also have the tangs in the factory location.
* It should be noted that these OEM BRP stock springs have had some known breakage problems. This factory spring has also had multiple revisions from BRP and some problems still seem to exist. Torsion springs on 1200 models have had issues if higher preload settings are used. Some tuners have suggested using a heavier side pressure spring than stock and not using more than 16 lbs torsion.

* Be sure, if comparing springs, to always compare at the same load test heights or the comparison would be irrelevant.
