v6 posi-trac set up and install
hey guys, just a few questions. if i buy a posi diff. and 3.45 or 3.73 gears for my 01 v6 (i'd love to get 4.10s..but i hear they drop gas mileage) what else would i need to buy? and if you've done it with your car before, how much did it cost to install, or is it easy enough to do yourself?

you need: 4.10's for auto. Those are the only two gear ratios available for the 7.5'' rear end(3.73/4.10). You will need a tuner for an auto to recalibrate your speedo. Install can range from $250-400. You should also buy the rear end rebuild kit, just as an insurance policy that nothing goes wrong. Read the gear thread!!! https://mustangboards.com/general-te...ar-thread.html

another question....I know that 4.10s are the best performance wise, but is it true that they decrease your gas millege? its a small concern for me, so in that case would 3.73s work better, or can autos ONLY have 4.10s?

really? i thought i read somewhere that sixers came with 2.73s stock, but whatever.
