If anyone out there has a rearend for sale. Could you pm me. I have been looking every where for a while now. Just cant seem to find any good deals. Thanks

why not just upgrade your 7.5? its a strong rearend. I put a 3.73 and a locker in mine put over 60,000 on it with no problems. I used to do burnouts and hard launches every weekend. "track days" its cheaper to upgrade than to buy an entire rearend.

How much engine mods do you have? Even an upgraded 7.5 can only take so much Torque, if you have lots of performance mods it would be wise to upgrade to an 8.8, they can take a lot more abuse.

I have every single Bolton you can put except nitros. I tracked it every weekend best et was a 12.9 @ 109mph. Vortech supercharger w/10psi pully, jba shortie headers throttle body spacer with 295/30/19 pirelli p-zeros in the rear. Havent had a single problem with my setup. And I used to drive it 160miles on a daily basis back and forth to work till my wife and I got a home closer to where I work.

You're running a s/c on the 7.5"? I didn't think you could but that's awesome!!!

You can with a good locker.
Auburn has a very strong locker and can withstand a beating from what I've heard

Enorym · 05-08-2012, 08:31 PM

3.73 motive gear ring and pinion and a Detroit locker. You drive to the track and do this every friday, saturday of the year then go home take your wife or gf to dinner then drive it back and forth to work, school. And have your brother record you doing epic slomo burnouts.

By the time you add up the parts and installation it isn't cheaper to build a 7.5 - in fact it was actually cheaper for me to swap the rear end than it was to build the 7.5.

I broke the 7.5 with a set of Richmond - supposedly indestructible - gears with just a tune and set of drag radials. Enorym - put a set of sticky drag radials on instead of the street tires and your 7.5 will break. The street tires are saving yours right now; it won't take many launches at the track on drag radials to find the 7.5 is the weak spot.

A brand new take off from newtakeoffs.com is around 1.1k, it's got T-Lok and your choice of 3.23s 3.55s and 4.10s... they stopped selling 3.73s... Keep in mind completely brand new

Enorym · 05-08-2012, 09:07 PM

Every time I track I run my micky's. I built my rearend myself and shimmed it properly. Didn't break yet "crosses fingers" but then again the las time I've taken it to the track was over a year ago.

For my parts it cost me something like $450-500 back when i hit 60,000 miles from Randysringandpinion.com and then the locker was a direct purchase because I have a wholesale account with eaton. My goal was to build a low 13 second street car that got 20mpg or better. That I could drive daily and have fun with. So I didn't need all these other cars. Reliability was my primary objective...then smogability. I'm a former Michigander I used to run up at Milan prob seen me out there a while back.

I have the sct tuner and cai. Thought about just puttin in gears and tlok. But figured I might be able to get the 8.8 cheaper when all is said and done

I was thinking the exact same thing before, but then i realized it would be so much easier to just buy the whole new axle with the gears and t-lok in it already.

dolfin13 · 05-10-2012, 11:25 AM

How much did u pay for that?

Atrav83 · 05-10-2012, 01:26 PM

He didnt, he doesn't have a mustang. What he says it out of theory not experience

Yea i was talking about theory, not experience... I have been pulling together a plan/list of stuff i'm going to do/get when i get the Mustang. So i've pretty much been doing homework instead of experiencing.

although if my plan works out then I will be getting one early to mid August.

I'd like to build another 4.0l but make this one a sleeper. Completely stock except for turbo or sc even ride height and other elements besides engine and tires would be stock. A electronic dump to throw open to surprise people.

BIG_K · 05-10-2012, 07:33 PM

If your going to mess with your rear end at all you might as well go big or don't do anything at all. Go with an 8.8.

Atrav83 · 05-11-2012, 12:10 AM

Definitely go 8.8, I'm trying to find one mysel right now b4 I save up for the xcharger

In that case why not a 9'? Hehehehhe

ponyboi06 · 05-11-2012, 04:57 PM

Saving for my 8.8! AM has brand new 31 splines, 3.73 gear, t-lol for under $1500. Then all you need is the cobra flange to fit the driveshaft

its very hard to find a 9 inch rear end that will bolt up to the frame of or mustangs. Its more than possible but some fabrication work will be definitely be needed! just got 8.8 Its plenty strong enough to handle anything you through at it

I don't think he was serious... He was probably just trolling us.

ponyboi06 · 05-12-2012, 09:40 AM

Summitracing.com has a new 9" rear and 31 spline axles that bolt on 05-09s for over $1400, then you still have to buy your gears and t-lok

Not trolling...he just said why not go with the best. That was my reply.

I'd buy it if I was blowing rearends. But I haven't so until then I'll stand by my 7.5 it's truly reliable for what abuse I've put it threw. But then again remember I built my own rearend and shimmed it myself made sure the tolerances were acceptable and torqued it down all properly.

It's got about 70,000 on it no noise or any problems. I ha my seals leak for the first month because I used non-synth. Did a 500mile fluid change with synth and it's been fine ever since.

The best rearend I ever had in any of my cars "including the drift cars I've owned".

I just didn't know there actually is such thing as a 9"... I guess i learn something new every day lol

Enorym · 05-12-2012, 08:32 PM

9's are more popular for the old school hotrod'ing guys and drag racers. My dad used a few in his heavily modified Morris minors that he drag raced.

dolfin13 · 05-13-2012, 07:54 AM

i will just probably wait and buy the gears and t=lok

If you've never built one make sure you take it to a shop to assemble it. For my parts alone it was under $500. Also look at the Detroit locker and other LSD's before you settle with the t-lok.

The t-lok is better for daily driving. My locker clicks all the time when turning sharply its annoying, and people look at me like something's wrong lol.

Next time you change your gear oil in your rear diff, try adding the friction modifier the 8.8 calls for. Might eliminate your chatter as it does for the 8.8.

I don't have an LSD I have a locker...lockers make a clicking noise when you turn sounds like base ball cards in spokes. It's a binary on or off diff. It doesn't require friction modifier.

I guess it's something I have to deal with to get the reliability and launches.
