3.23 to 3.55 or 3.73

I switched from 3.23 to 3.73
Daily driver mostly in town
Works excellent!!
2200 rpm = 45 mph.
3400 rpm = 75 mph
With 255 x 60 x 15
Awesome yeah I think that it's something that will complete the drivetrain build for me besides getting bigger tires, did u have to tub the rear to fit those? I was always think biggest to fit in rear was 235s
