chrysler 8.25 vs ford 8.8

[IXNAYXJ]

Powertrax makes a noslip for the 8.25 29 spline.

Yes, but it's not a "lunchbox" locker; you have to redo the gears and it's the locker itself is not cheap.

I beat the snot out of a lock-rite'd 27 spline 8.25 on 33's for a couple years with zero breakage. The only reason I got rid of it is that I was going to 4.88's in the front axle and couldn't gear the rear to match.

I now run an 8.8 and love it, but for what you describe, the 8.25 would likely be fine. If you want to run disc brakes at some point, though, just save yourself the effort and go 8.8 now.

You don't have to redo the gears with a No-slip. I've had mine out a couple of times. The worse thing about the install is the inner springs. Also it only takes about 2hrs. to put disc. on an 8.25. JIM.

8.25s are semi-float and can't use true alloy axles. But I would bet you would be hard pressed to break 1541s.

Dude, the word alloy doesn't mean a specific steel. It just means a different "mix" of basic steel.

Basic steel is iron and carbon (and a few other things in very small quantities). Any time you add anything else in you are making an alloy of steel. By definition.

So someone adds Manganese to the mix (more than 1%) and you get 1541 (1.35%-1.65%) in this case. Guess what 1541 is an "alloy" steel.

My point is, just because it isn't 4340, doesn't mean it isn't an "alloy".

But you are correct that no one makes 4340 8.25 shaft.

Maybe I'm a little biased, but I would go 8.8 over an 8.25. It has a larger ring gear, shafts, tube, better brakes, and slightly lower gear choices. Do what you want, cause both setups are an upgrade for your rig. Good luck on the swap!

8.25 or ford 9. If we are arguing for the 8.8 based on strength and aftermarket support go for a 9". just as muhc work to put one in as an 8.8...

actually, the 8.25 isnt really an upgrade if you had a D35. the internals are very close in size to the D35, so you'd basically have a glorified D35.

I havent seen a person yet that has put any amount of money in an 8.25 and not said "I should have just gone ahead and got the 8.8" while their wheel and a shattered nub of an axle shaft is rolling down the hill.

This thread alone has quite a few happy 8.25 owners. Did you read any of it?

I don't know what you're talking about...

D35 vs 8.25 (29-spline)
Ring gear = 7.5" vs 8.25"
Axle Shaft diameter = 1.17" vs 1.21"
Tube diameter = 2.62" vs 3"

Need I go on...?

That's not "very close in size to a D35" in my opinion AT ALL.

the 8.25 is much better then a d35 imo, larger r&p, larger housing and tubes.. Most d35's fail because then the housing flex's it causes axle's to break.. As i said i run a 27 spline 8.25 with alloys and a lock-rite 33's.. and im pretty hard on it..Im not going to upgrade it, Im going to keep running it on 33's because iv ran it for a year, Basically everyweekend and i havnt ever had any problems on the trail with it,..

x3 on the 8.25 being way better than d35. just look at the #'s

Xwhatever. You're right xalexjx, but it's not an opinion...it's a FACT that the 29-splined 8.25 is stronger than the D35. Apparently, he doesn't know what he's talking about when it comes to those axles. Like said above, it's bigger in the ring gear, axle shafts, and tubes....hence stronger.

If you're NOT planning on going over 33's, I'd just go ahead and put the 8.25 in.

 

[trail rate this]

I took out a 29 spline 8.25 and swaped in a 8.8. Easy swap and disc brakes.

 

[The Hard Struggler]

I have a Super 8.8 with an ARB. That said i've seen ShortXJDoug POUND on an 8.25 with a Detroit and 29 spline Yukons with 36" Swampers and a total disregard for the rev limiter. I think if you are only going to run 33" the 8.25 will serve you well.

I guess you're right, I guess its because they all fall in the "stock, small axle" category. Isnt this the MODIFIED forum?

What? That doesn't matter. The 8.8 is "stock" to a Exploder and Ranger, so what. The fact is, the 8.25 is stronger than the D35...I'm not the only one who says that so good luck fighting that battle if you start it. How can you sit here and say it's not??? :twak: Especially after you see this...

:huh:What? you mean to say the D35 is weaker than the 8.25?

Like said before, if you are not going any bigger than 33's stick with the 8.25. Swapping one in will be waaay easier (and cheaper) than doing an 8.8 conversion. Although if you do go 8.25 it is probabaly worth it to do a disc brake conversion.

I have the 8.25, no-slip, 4.56's, and Alloy USA shafts, 33's and it's been great.

The only thing that sucks about the 8.25 is the c-clips, but you'll still have those in a 8.8 unless you do a super kit.

 

[99XJWhitey]

...and a D60 is stock on a 1 Ton pickup, but you dont see me hesitating to put it under my Jeep. The point is, the D35, 8.25 (either spline count), D30, are all in the stock light axle category, IMO, and I see them bust all the time, it used to be with me driving, but Ive since upgraded. So why bother with an 8.25 if you have the option of having a 31 spline 8.8 with disk brakes that dont have to upgrade in order to make it stout enough to wheel it?

you see 8.25 break all the time???

 

[MoparManiac]

Um...you don't have to upgrade an 8.25 to make it stout enough for wheeling...
