Is The 31 Spline Ford 8.8 Rear Axle Strong Enough: How Did It Fail?

[@taterkuhn5048]

After putting a serious G Force transmission in my car with a good Ram adjustable clutch and breaking the 8.8 rear gears 3 times. I got a Fabbed 9” from Quick Performance with 35 spline axles. Best 💵 I’ve spent. Been 9.80 with it no issues NA on motor. When setting up a rearend. The 9” is so much easier

[@LynnTwinCustoms513]

I’m in the same boat. Adding horsepower and still rocking a stock 28 spline c clip diff with upgraded clutches. But with a t56 magnum and a twin disk clutch I can tell she isn’t gonna last very long with how I been driving it

[@NoFox_Given]

35 spline Strange Hy-Tuff axles, Spool, C-Clip eliminators and Fully Welded tubes in my street car with an Anti roll I never unhook. Been that way for years, only issue I’ve ever had was twisting a Yukon 31 spline on the street making test pulls.

[@mjp1802]

This is great!! Looking forward to more diff building content.

[@robertwood3970]

The 31 spline Explorer diff holds up really well. I set one up in my Tbird SC 12 years ago and it is still going strong. I am making 390 to 400 wheel.

[@williamlane6374]

Hell ya. That's what I'm about to do to my rearend, to fix alot of issues

[@davidhudak7203]

Send me an angel. Great intro song!

[@380.motorsports]

While I agree that C-clip eliminators are a good upgrade and if staying with drum brakes should definitely be done for racing. The budget way to prevent axles coming out when broken is to convert or use the disc brake versions. A broken axle is not exiting the housing with disc brakes. Am I wrong?

[@Neomustangs]

With c-clip eliminators they can’t exit either …

[@edsompayrac1717]

I don't drag/race my car. Just upgraded my dif with the Auburn pro diff 28 spline. Then hardened axles .

[@brokentoolgarage]

Nice! When I get back on my 89 Mustang, I will need to rebuild and upgrade my 8.8

[@GrandPitoVic]

Great info brother. I have a 03' Crown Vic Police Interceptor that will be around 400ish to the rear wheels. I will definitely be doing some up grades to my 8.8. I know around 03' in the Vics is when they changed from 28 spline to 31 spline. I will find out what I have when I open it.

[@edsompayrac1717]

Listen to that spool diggin! 😂 Sounds just like trying to move our dirt cars around the driveway

[@Neomustangs]

Haha probably what really bent the axle tube tbh

[@awee5816]

😲 Wow! 31 spline axle can hold a 1,000 horse power 💪 for years? Is it in general or is there something special about the Explorer' Spline?

[@Neomustangs]

Always raced on slicks. Had a clutch that slipped. Car wasn’t at that level much. Spent most it’s like 800 range

[@awee5816]

@@Neomustangs thanks 👍.

[@MustangGuy6501]

Great video, Is there anyway to use the 99-04 rear disk set-up but use a 4 lug rotor? I wonder if ones made like that

[@Neomustangs]

Not sure ?

[@michaelphillips-mb6sp]

I installed jy p heads without doing anything to them, car ran fine, I then upgraded springs and valve seals, now will turn over but won't start, what do you think it is?

[@ZacharyBraxton-m1f]

You guys got to it right on time before you break anything.

[@paulhudgins5120]

Great content, rear diff takes a lot abuse, as the power increases, beefing up the engine, and trans, the rear diff is the weakest link in the drive line.

[@Neomustangs]

Often one of the last mods done too

[@AutoInc420]

Spool Ha try to push by yourself if it break down on u in traffic that a struggle believe u me

[@Neomustangs]

Uh we been spool for years. I know what that’s all about. Hell you can turn the wheel. Park the car and it’s like an Ebrake

[@89gt5.0]

If known what 8.8 4 lug options are out there that has 3.55/3.73 gears or full rear and that will fit a fox with stock length axles?

[@Neomustangs]

87-88 turbo coupe

[@northwestsuburbs20]

Needs upgraded to 35 spline axles and 9in big bearing ends should be solid then.

[@Neomustangs]

I talked about that in later part of video

[@scottglaister158]

so what happens if that would have came apart at 100 mph ? asking for a friend

[@Neomustangs]

Probably not good things.

[@paulbalzarano]

Personally, would never run a spool on the street for so many reasons

[@Neomustangs]

Ya I didn’t have much of a problem with it.
