they should come in just shy of 33"...
I ran them on my reg cab 6.4 and liked them. They hook really good, they're light, and the shorter diameter keeps the revs up for big turbos, etc.
I took them off because my truck is stock turbos and is a 3.73 truck, so it was a little wound out vs. what I wanted...
if I had 3.55's, I'd still have them on the truck.
For a street truck, the're really tough to beat. They wear out quicker, but they wear surprisingly well. I expected them to go away like boggers or drag radials for some reason, but mine have about 10k miles on them, and they still look like new
