only problem i have with that is i just dumped about 300$ in the rear breaks not even 3000 miles ago.
you guys think 4:10s will be good with 37s right?
he said his runs like 2400 rpms at 70!!!, thats alot of rpms.
what do yall think it will run at 70 with 37s and 410s?

i have 35's with 4.10's and i about 2000 rpms at 70.

but im not happy with what i got down low. 4.56's are in my future when i bump up to 37's. you might like the 37's on the 4.10s but i think itll be too tall of a gear. i think its even a little too tall for 35's. but thats just MY opinion

You know its not that hard to change brakes. It would be much easier and quicker to swap axles and brakes than spend the time to set up 2 sets of gears.There is a chance you could swap the gears and not have to reshim them but I highly doubt it. FYI the shims require a press as they are located between the bearings and the carrier. You have to press the bearings off, change shims and then press them back on. Unless you use a set of setup bearings. THey are machined to fit a little looser so they don't need to be pressed on and off.
