Okay, im going to a 2.7", possibly a 2.6" in the winter and I was wondering what would be a better setup! Just using the GM S2 Belt(Cheap Way) or buying the ZZP Tensioner(More Expensive Way)? I heard both work well but im looking for the best Non-Slip Combo here....
Help me out guys!! Thanks

 

I'm running the Stage 2 belt with my 2.8 right now, no slip. And it looks like i have a good amount of room for the tensioner to let out too. I'm going to a 2.6 in a couple days. I'll let you know then.

 

whether you use the aftermarket tensioner or not, slippage is going to rely on belt condition. Just get a good belt of the size you need. I personally go with goodyear
