12 bolt 4.10's with Auburn pro diff - Lateral-g Forums

GM Muscle · #1 03-21-2011, 07:08 PM

i have a set of 4.10's in my 70 chevelle 12 bolt that i would like to trade for a set of 3.55's or 3.42's. I sold my 6spd and and need a little less gear in the rear. I believe they are richmond gears. i also have the auburn pro diff that i would no longer be able to use. so if you have a 3.55 or 3.42 rear end setup with an eaton or auburn setup and want to swap over to a 4.10 setup, hit me up. these parts only have about 5000 miles on them. If there are no takers soon ill just order new stuff and put my old stuff in the classifieds...

Probably telling you something you alerady know but you can get a 3.73 gear for a 4 series carrier from Richmond. That is the lowest gear they make for the 4 series. Not sure if that get you in the rpm range you are looking for but would save you from having to buy a new posi unit.

Might be interested in them if you decide to sell...unfortunately all I have are stock 2.73's & an open diff for trade.
