5%.For the ones running the 7.3 4:30 gears on 37's how does it handle the size? Im currently on 35 Toyo rt trail and thinking of going to a 37 AT.
My speedo is 5% off.
Your big block won't notice, and in fact might pick up a few tenths in the quarter mile.
4.30 is a LOT of gear. Designed with 37s in mind.
