When I picked up this sled a couple weeks ago it had a OEM Polaris belt Part No. 3211080 and no spare belt. I ordered a new belt from the JRGraham website and they sent me what appears to be the wrong belt. It is a Dayco HPX5020 (Replaces 144-4640) . Can anybody varify the proper Dayco HPX or Ultimax belt for this sled? Thanks - MATT

the dayco belt i use is the 144-4640

How did you find the Dayco belt held up?

ultimax 3 are awesome

I've yet to see any aftermarket belt last as long as an 080 poo. Ultimax3s are just as much as an OEM one.

I can't figure this out? I put the new Dayco HPX5020 on my sled and it was definetely the wrong one!!! Right on the sleeve it says HPX5020 Replaces 144-4460. I installed this belt and the sled.... started it up... and the sled started walking at low rpms!! it was engaging, slipping, and creeping forward at idle speed. I immediately shut it down, took that belt off and replaced it with the OEM Polaris belt and everything seemed fine. Upon further investigation the HPX belt seemed to be thicker? anyone else ever experience anything like this? -MATT :beer:

The exact reason why I never use aftermarket belts. They arent ever a perfect fit.
