Many of you may already know this, And than again many may not.....The weakest internal part and the workhorse of the TRA happens to be the spring. Same goes for any other brand of snowmobile clutch as well.........3 XP 163 were used in testing springs by BRP, Dalton, EPI, Renton and Team.
After 700 miles it was no contest it was Renton vs BRP, Dalton, EPI and Team. The Renton Ti spring never stops pinching the belt under deep powder mountain riding conditions regardless of which ramps and helix profile we used Dalton, Team and EPI would begin to fade at approx 200 to 300 miles. When the spring begins to fade you are no longer consistantly pinching the belt through each shift of the TRA. The $15.99 BRP spring showed signs of fatigue and fade after 1 day of hammering on steep hills for the better part of the day. Once your spring begins to fade all sort of issues begin to occure with the TRA such as lack of rpm, inconsistant upshifting, slight clutch bog/hesitation and hot clutches resulting in worn belts. If maintaining peak consistant performance is a big deal to you like it is to me have a real close look at the quality of wire being used in the spring you are currently useing.
If your always clicking up your clickers, all your trying to do keep your belt pinched. If thats the case there's a pretty good chance your clutch spring has lost 20% or more of it's force. Once the TRA heats up the only internal part working it's azz off and fatiguing under the heat of the TRA is the spring.
Do the search under Renton Coil Springs, you get what you pay for imo.
edit: EPI Springs would be 2nd choice
