Axle Choice??

Running Stock bodied Demon - approx. 500HP, run Mid 11's (Hopefully a bit quicker)
904 auto - no brake, 4.30 rear w/30 spline spool.
What is the axle of choice?
I'm not worried about upgrading to a brake or more HP in the future.

Thanks All!!

For a budget type build, Moser makes a decent axle. My only suggestion is to upgrade to 5/8 studs while you are at it. The little extra that it cost, is worth it in the long run.

Definitely go w/ 5/8" studs now. They're easier to work with and a pain in the rear to upgrade to them later on.
I like and use Moser axles. Not a fan of Strange axles.

I agree with Moser, I use and like them as well.

The 5/8" stud idea is great also but factor in your street wheels(if you have any) with that decision. It is not always as simple as drilling a wheel out to make the larger stud work.

I'll be upgrading to a 9" soon since gear sets are hard to find for a Dana 60 of late.

i'm going to ASSUME it has a 8 3/4 rear end in it now, correct?
If so does it have a steel cap on the driver side?
If not get one soon
Mark Williams and Strange engr. should both offer them
I've seen way to many stock iron caps in multiple pieces after failing, NOT GOOD

It does have the Steel cap - Thanks Cab!!

Has anyone used the axles from Doctor Diff?
He says they're as strong as Moser/Strange.....$300/pair w/green bearings installed.
Yes I'm on a budget but I don't want junk....

Thanks All!!

8 3/4" ring & pinion is the weak link. Then the cap. Not sure where 30 spline race axles fit in, but I've run 35 spline 1/2" screw-in stud Moser axles for many, many years without problems. - 360/904 footbraking @ 3,540+ lbs running mid-low 11's averaging 1.52 60' times. Combination of weigh with good traction & 60' times cause the most problems. Never broke a cap, but there were signs of "cap walk".)

I'm a believer in the Dana60; mine was bulletproof with 640HP on slicks, low-10s, SB Duster.
Strange axles. Originally set up by Herb McCandless, went hundreds of passes before I did a precautionary R&P.
In a heavier drag car car I'd consider a Dana60 mandatory, and have done exactly that.
I've seen enough broken rears spit a car into the wall; makes for a crappy day, to say the least.

We will find out soon. I just installed a set in my 64 Dodge wagon. 8 3/4 sure grip and should run high tens.

At that power level, it's likely not very critical - I've used Strange, Moser, and Dutchman without issues around that power level. It probably comes down to availability at this point if you have a timeframe.

I recently bought a set for a stock length B-body Dana 60 so they are basically a stock replacement. This is a street/show car and not a race car. I couldn't tell who made them, they looked like a Chinese knockoff. The splines are much longer than they need to be probably because they blank out a common larger length axle and cut it per application. So far I have no issues but had I known I just would have paid more for the name brand axles(Moser, Strange).

I have used Dr. Diff's 35 spline axles in my D60 now for 5-6 years. 3740lbs, Trans Brake, Radials, 1.37 60ft behind the turbo small block.

It ate a stock planetary, and rear sprag in the trans (with Low Band Apply!), but never hurt an axle.

It did bend the 1/2" wheel studs, so I upgraded to 5/8".

I have. They work very well.

We use them with a spool in a 3,700 lbs. street car in a Dana 60. It's seen 1.36 60 ft. times and we beat on the car regularly.

I would highly recommend getting them minus the garbage 1/2" studs they come with! We bent them as well. We put in Strange studs and all has been fine since.

30 or 35 spline spool?
Any difference in strength of them?

There is a substantial difference between 30 & 35 spline axles. I know of at least one manufacturer that shows a comparison, but don't recall which one.

FYI -35 spline 8 3/4" and Dana 60 are basically the same! But Dana 60 has the 40 spline option with 5/8" studs if that's a big concern.

I used a set of Strange 35 spline race axles and spool in my old low ten second pump gas Duster 3450 Lb. streetcar with the original 8 3/4 rear end with coil overs and ladder bars until it ended up bending the crap out of the rear end housing: shock
I was able to reuse the axles in a Dana 60 housing that I had narrowed and had the axle ends replace with new Moser ends, no problems with rear ends after that :
