How Strong is it?Rear end

94 DropTop · Mar 6, 2008

How much abuse can the old 8.8 take? Im going to have it rebuild, 4.10, steeda drag springs, control arms, possibly a 3000 stall and MT e/t drags. Could the 8.8 take this abuse? given its an auto so not really any high stall launches, everything but the stall is garenteed to be on the car.

An 8.8 will laugh at that, Ford did one thing right for sure, which is bless us with an overkill rearend.

Pry just need some 31 splines... I think you would be alright then.

94 DropTop · Mar 7, 2008

dont have the money to do the new diff and axels so im keeping it 28 maybe some hardend 28's in the future if i need to.

SMOKEDURVTEK · Mar 7, 2008

I feel ya, thats next on my dinner plate. Moser 31's and w/e else i need in there. Then its time for vortech S trim.

Provided your trak-loc is in good working order, you'll be fine.

No need for 31 Spline axles...

If anything just get a set of hardened 28's.

My buddy has had a set of Moser hardened 28's and he puts 520 RWHP in a manual 93 GT. He beats the hell out of the car with ET/Drags and never had a problem.

The stock traction-loc will take a good amount of abuse....there are people that go well in the 10's with them.

If your doing a complete rebuild I would just rebuild the stock t-loc with one extra clutch per side.

yup its getting rebuild when the gears go in. its also getting a girdle

OnyxCobra · Mar 9, 2008

the 8.8 will be fine but definitely go with hardened axles.

97stanger · Mar 9, 2008

ill only have 400rwhp and i plan on building up my rear with an eaton posi and moser 32 spline axles fairly soon. If you order your moser axles from American Muscle they come with hardened studs just to let you know .

94 DropTop · Mar 9, 2008

If you have ABS it is a lil more work than normal but - it's not rocket science. Pretty straight forward.

94 DropTop · Mar 10, 2008

yes sadly i have abs and i hate it. i picked up the slicks last night :dancing6: they are almost done but should last me this summer if figure atleast 20 passes minimum. how do you tell how much life they have left?

93deznutsblown · Mar 10, 2008

I leave at 4-5500K depending on my mood and the 8.8 in my car is stock with 3.55 gears..
Its never had a problem...

It will be nice to see you car on the road or track. I dont think I have ever seen it...
I'm on Wichita Racing also...lol

94 DropTop · Mar 12, 2008

dont know if you saw them before but i picked the slicks up from anlumi. Do you know how to tell how much life they have left in them?

93deznutsblown · Mar 12, 2008

I have not seen them but usually when they stop smoking when doing a burnout they are toast. As long as you stay off the street with them you should be fine. Isnt you car an auto?? If it is they could last you all year long...you may even bog out of the hole.. Have you put them on yet and tried them??

Venom351R · Mar 16, 2008

I went with MT ET Streets and as not to chance it up graded my rear end anyway. Figure it saves me from doing it in the future. Its not your 8.8 that you have to worry about its just the axles. It all depends on how much traction you get and how hard you dump it off the line if your drag racing with it. Hardened 28's may be fine they may not be it can go either way. You can find 10 people to say they busted the 28's at the track and find 15 that said they were fine. Im running Moser 31 Spline axles w/ an FMS limited slip.

PS: its not your HP that will break anything its your TQ and the sudden jolt to the drive train when launching off the line. Being at 390 FT LBS with more on the way it was nothing I wanted to personally chance.

LAFENATU · Mar 17, 2008

Like I said before, with an automatic - unless your using a transbrake, 28's will be fine.

1FastGT · Mar 17, 2008

the ford 8.8 rear ends take ALOT of abuse and ive seen them hold up to 500+ hp. just rebuild it with new clutches and put like lucas friction modifier in there. youll be fine.

Stangbangin · Mar 18, 2008

I run a rebuilt 8.8 with stock axles on a 200 shot and slicks and spraying a 50 dry shot off the line for about 12 months now and the 8.8 hasn't even blinked and I dump off the line hard. I've pulled 1.75 60's so I doubt you'll give it any trouble.
