The new #348541 Ultra Stable Clutch Spring has very similar characteristics to the #348540 Conical Clutch Washer Spring Set. The main difference is that the new ultra stable clutch spring works in a wider range of conditions and is easier to install.
In order to eliminate spring deformation during use, the spring was pre-compressed as part of the production process. This results in the spring having a slightly shorter length. The length and characteristics of the spring will remain consistent even after a long period of use.
