Belt size issue
Good Day
A friend has 2015 C7 ZO6 with a F1X installed
Pulley size 4.0 (10 rib)
He is having an issue with the belt size
He tried Gates K100485 its a bit loose and K100465 is small.
is there a size in between and are there any other brands that are better than gates?

A few years ago I was doing a custom install of a crate LS3 and NAPA said there were many belt lengths in roughly half-inch intervals. I simply measured about what I needed and got a couple of the closest to try. I'd get the approximate length needed and start in similar fashion, or at least ask them (or similar) if there is an in-between length. All the best.

I had no trouble finding an exact match at NAPA for the size I needed for the non adjustable alternator mounting in my Cole drag boat.

bumping this super old thread. Did you ever find the right belt? I’m trying to source a k100475 but can’t find one
