Sled Guy is spot on about not lasting as long
Not to give S.G. a hard time (not at all my intent), he's given me some great tech advice often in the past..... the Polaris Belt chart shows the 3211080 belt is narrower than the 115 belt by a hair over .020".. the belt side angle is different as well.... 28 degrees compared to 26 degrees.
The 080 belt is a different compound and has a bit more grip to it... It will change your clutching a bit and you may have to change weights to get the same RPM.
The primary would need to be re-shimmed to get correct side clearance for proper performance .... you would need to check to confirm... shimming is not somthing that many people have the tools or experience with. Not a laymans job.
The strenght of the 080 belts pale in comparison to the 115 wich should survive a nuclear attack. The 115's are more abrasive on the primary clutch.
