111.5 on a 2.8 pully will slip like crazy. Go to autozone and pick one up

[Holty]

OK, called Autozone, they can have one for me tomorrow morning, it's a 110.5" for a 2.8" pulley. right?

your goal should be to have used about an inch of travel on the tensioner, so whatever belt will give you that, will work fine

I don't think there's any need to panic, you have the newer style bracketry with the adjustable tensioner.

This works for me:

 

3.3" stamped (*actual 3.1") OEM Radix pulley = 061120 belt

 

2.9" = 061115 belt

 

2.75" = 061110 belt

 

 

All above are with idler and tensioner pulleys that were supplied with my Radix kit.

 

*The pulley that came on my Radix is stamped 3.3" but actually measures 3.1" OD on the surface where the belt rides. My 2.9" and 2.75" pulleys actually measure the same OD at the belt surface as the indicated size.
