Whipple 2.9L Gates RPM / HD belt size for 6 rib setup - Camaro5 Chevy Camaro Forum / Camaro ZL1, SS and V6 Forums

I'm currently in the market for a better serpentine belt as the Whipple provided belt stretches a lot, and that is alarming. I'm not sure the belt I should be using as Gates neglects to post their belt size specs and only gives it in their part number codes, that most people (including myself) don't know how to read. Please help me determine the belt I'll need for my stock 6 rib setup!

Do note I run a Griptec 4.00 pulley and a fluidampr harmonic balancer that is also stock size.

Here's a chart...https://www.wanderlodgeownersgroup.c...20Listings.pdf Use K06 for 6 rib.

I ended up buying several progressively smaller belts from an auto parts store until I found one that was hard to get on (K060910). Once you have that number, you can add an "HD" to the end for their Heavy Duty belt or "RPM" for the Race Performance Muscle.

I ordered a K060910RPM belt from RockAuto ($50.79 plus tax & shipping) and it should arrive today. Not sure when I'll have a chance to install it but I will create a thread when I do.

I am running a 3.75 pulley so the K060910 should be too short for you.
