okay im definitly going to put on some new gears and diff lock. but now im thinking of just buying a new takeoff 8.8 with 4.10s and the diff lock. but i need info from people who have done this. is it worth paying the 300-450 more? and can u feel the extra wieght cause this is my main problem in gettint it. i know ull probably say to get it if thinking of going the vortehc or supercharger way...and i am in about a year. but our 7.5 will hold up. so is it worth getting the whol 8.8 rear end????
well... i have an 8.8 that I'm in the process of getting ready to place on my v6 here within the next couple of weeks. i got my takeoff with 3.55 gears and 15K miles on it for $225 locally (good deal, I hope). If you're willing to wait a bit I'll give you all of my impressions once I perform the swap the last week of march.
OK, if you go with the heavier 8.8 you need the right GT springs and shocks or wheel hop will be out of this world. If you go aftermarket springs, get em for the GT springs and not the V6 springs for the rears. Its the unsprung weight, not the sprung weight that is different with the 8.8 VS the 7.5. Also get the 8.8 that has the V6 Pinion Flange.
Its totally worth it for the T-Loc, gears and heavier axles with more splines.

what are you talkin bout? i run stock springs/shocks in the rear, and have zero wheel hop.
im pretty sure they are even the same springs for v6/gt in the rear, and possibley even the shocks.
go to fordparts.com and search for the part in their OEM catalog.
Part # E9TZ-4851-A i got the pinion flange for $28+$10 shipping
I would have thought that the since the axle is part of the suspension whole rear linkage system that the v6 springs would be just fine since the weight of the car is pushing against the axle and not the other way around...
EDIT: according to the website i posted above apparently the rear coil springs are the same for both models (v6 and GT) - it's the shock absorber that is different - possibly because the gt is heavier and had suspension set up a little more aggresively?

so 157db is totally wrong about the whole GT springs. cause that kind of put down the 8.8 rear buy i had in mind. cause if i have to spend more money on springs i wont do it. the rear end is already 900 bucks. so it is just a srtaight bolt on right. no other parts neede except for pinion flange.
i broke an axle in the 7.5 broke the tlok and jacked the bearings, snapped a control arm with the stock 8.8 now i have a truetrac differential in the 8.8
if you plan on any kind of f/i id go with an 8.8. even at that, with the 7.5 i broke the axle while n/a. im a bit more agressive launching than most lol
Explain how hard of launches you need to do to ruin a 7.5 though, I think most people here think getting an 8.8 is a must even if you don't go to the track.
