I have a new 3rd member for a 9" and it has new 3.73 gears and a detroit locker and aluminum pinion support and a 1350 yoke. Gears already set up. Gears and Locker are Brand New. 31 Splin Axles.
Im needing a 4.10 gear and True Track Posi unit that is all set up, would like to just swap out with someone that has one already to go.
ANyone know anybody that might do that for me??

 

why not just use that one.

 

Its a daily driver so we dont want the locker+the car has 4.10's in it, we just want to stay with the same ratio.

 

i couldnt find a non locker 4.11 ratio when i had a 9", only non lockers i could find was 3.89 and lower.

 

i guess 3.90 would be the next best then.

 

yea you should have no prob getting a 3.89

 

then again i had 35 or 40 spline, not sure about 31.
