I planned on upgrading my gears to either 4.10 or 3.73 leaning to the 3.73 since its an everyday driver and a T-Lok should I just stick with the 7.5 rear end or just upgrade to the 8.8 with the T-Lok and 3.73 from newtakeoff.com

depends on how much power your makeing


gears 150-200
install 300-400
fluid change 50
install kit 80


730 ( useing highest values )

or 850 bucks
2005-2009 Mustang GT 8.8 Rear Axle Assembly 3.73:1Ratio w/ABS w/Trac-Loc Pinion Flange Only Fits Mustang GT


now if ur gonna make over 350 RWHP id say 8.8

if not 7.5


if u can do your own labor and have the extra money 8.8 would be nice... but eitehr way its gonna be near the same ammounts

For 100 extra bucks you can with the 8.8 its a direct bolt in and if you decide to add more power later,and we usely do, you will be good to go.

im tired of being a 1 tire frier
