i just got my 3.73's in and need to know what speedo gear to get, i already ordered a 23 tooth, but i got to looking at the ad and it lists the same one to work with 3.73's and 4.10's. anyone know for sure how many teeth i need?
Actually, there is no gear for 3.73's and up. 3.73's, 3.90's, 4.10's etc. use the same one as 3.55's. It's as close as you'll get. That's why it says they're the same gear.
Nope, I think it's like 3mph at 70. But if you have taller tires than stock, it will even itself out. With my 315's out back, it's dead on at 70, radar verified.
well, there is a 5.05% difference. so with stock hight tires, you will be going 5% slower than your speedometer reads. 70 mph times 1.0507=73.55 mph. so there you go. a slightly taller tire will even that little bit out anyways.
