The belt that comes on the sled is a 127 Skidoo belt and it is too soft and creates inconsistency in the engine rpm, the gold series belt is too hard of a compound. The best belt we have found and recommend for the sled is the Dayco Ultimax 2 belt and the correct belt is Part# 138-4332, not the belt that the Dayco book lists (144-4353). Also be sure that your clutches have correct center to center and offset. -- Bill
Hey bill, Why is the 4332 better? I see that it is a bit wider and a little shorter than the 4353. Is that better for drag racing? I phoned they're tech line and they list the 4353 for the renegade but say you can also use the 4332. Will i see better top end with the 4353? Sorry for all the questions but i have always run OEM skidoo belts. Right now im running 127's on my sled and ladyk's 02 mxz700. They have a bit over 2000kliks on them and are due for a change soon. All they had in stock was the 4353 i hope it works as good or better than my stock 127.
