rear end

I bought my Eaton Posi off eBay, 31 Spline Mosers from ModularDepot.com and the FRPP 4.10 gears from MustangTuning (enter coupon code stangnet for 5% discount) along with the Install Kit.

Install for this was $350, but thats moderate to low considering ... so once you have ordered these parts look around for a shop that'll do it for $400 or less.

BTW - You're going to want to upgrade your rear end if you'll have 'sticky' tires on anytime in the future. Hard launches on the stock axles and diff isn't the best idea.

While you're down there look into having your torque boxes and axle tubes welded. In combination with a new girdle (FRPP) you'll have a pretty strong rear end.

i am planning on putting 4.10s in my car and i was wondering if i should go and ahead and put 31 spline axles and a locker. If i would go ahead and do that what else should i get with it? also where could i get all of this stuff for a good price? Would it be better just to get a whole complete rear end housing and all ready to bolt in or just do it all myself? If you guys could help me out i would really appreciate it. thanks

if the funds allow, while you're in there you might as well beef it up so you wont have to go in again when you break something. a word of advice if this is your daily driver and you drive in rain and/or snow dont get a locker. go with an eaton or even the F-150 diff's. a friend of mine has a double packed f-150 diff with moser 31 spline axles and it ihas taken everything he has thrown at it. dont buy a whole new housing because then you'll have the hassle of having to store or sell your old housing. just not worth it imo. as was already mentioned while your back there go ahead and get your upper and lower torque boxes weldded. along with your axles tubes. with the things that i have just listed you will a very stout rear.

locker != street use
