Depends how much power you wanna make your 7.5 is good for a daly drive up to 300hp if your going to make more then 350hp I recommend you upgrade to 8.8 rear. If its a daly drive just get a Ford racing T-lok with some 3.73 for 5 speed and 4.10s for automatic.Ok but how about the rear end ? Guy hasn't responded buy how about this one ?
Yea then just get a t-lok and gears and use the extra money for a new def. coverYa it'll never get over 300 I just am looking for the cheapest route and the t lok gears is $6-700 w/o install on am
