I've read some of the other threads regarding replacement of the supercharger belt. And honestly it is a very straight forward process. My problem is finding the belt that will work with existing pulley's and tension arm. I just received the Gaterback belt and it seems to be short. Anybody have part numbers for the belt that works without the upgrade of the pulley, tensioner? The goodyear part number is 4080515.

Does anyone know what belt will work on the Supercharger, without changing the pulleys and tensioner?

 

Looks like the alternative to finding a belt is to buy the upgrade kit which appears to be pretty salty. Any thoughts from the experts?

 

It may be XR821897 or non-OE alikes. If it is, they're all over the net.

 

Is that the discontiuned belt? I bought what I thought was the correct belt from Merriman Jag here in the states and it is too small. There is really no reliable cross-reference out there that I have found.

Thanks Jag V8

 

I used this one on my 2004 STR without tensioner upgrade.

I suppose the original # will be in this if you can find it http://www.drivehq.com/web/jfenley/P..._2000-2005.pdf
