Did some research for belts and found that some people recomend that the Dayco belt for a SP 335 was a Max 1107 but the demensions are 47 1/8" X 1 1/4" but other research show that it is a Max 1121 with dinenions of 40 7/8" X 1 3/16". Does anyone know the right number for a 99 SP 335? I was wondering if the gasket has to be changeed every time they are about $15 around here?

 

It should be the 1121 belt. That should fit all Polaris ATVs with out ebs. I don't change my gasket everytime. Make sure it is in good condition and that it is not twisted and you should be fine.

 

Thank you for confirming
