Time to replace my ( hate to say ) 22 year old Moser axles, 33 spline,12 bolt, big ford ends .
Moser or Strange , gun drilled or not ?
3200 lbs car runs 9.70-9.80

Nothing wrong with Moser. Stick with them. Don't need gun drilled unless looking to save weight

My opinion is Strange or Mark Williams. Moser makes decent stuff but for the life of me I can't understand why they don't coat their axles. Gun drilling is a waste of money in my opinion until you start chasing tiny ways to lose weight.

What ever you do I would move up to 35 spline axles.

Eric, is this a foot brake car or trans brake?

I agree 100% but if your going to invest in a new spool then you might as well upgrade 40 spline imo

Mark Williams is my choice in axles, rear ends and brakes

I run a transbrake leave from 3200-4000 depending on track elevation. The car has a Moser 33 spline spool in it.

eric I think its an excellent idea to get the 22 year old axles out!!

I went through an axle thing this summer where I need a lot of strength but light weight...I had the moser 40 splines in mine that where about 12 years old.
I ordered a new set of mosers with their lightweight option and gun drilling.when I got them they where 8 lbs heavier than my original mosers.they looked like they had just been carved out of a hunk of metal and the gun drilling was off center.
im sure they would have worked but the quality and workmanship looked really poor..

I decided to order a pair of the lightweight mark Williams and when I got them a couldn't believe the difference in quality..the mark Williams workmanship was beautiful and the came in 8 lbs lighter than my original moser.

the difference in quality was astounding in my opinion...even the drive kit that came with the mw axles you could tell the workmanship was far superior..and surprisingly the mark Williams where only slightly more than the mosers

22 years like that I don't think I would be too concerned about moving up to 35 spline unless you just want to spend the extra for the spool and bearings. Seems to have served you especially well.

Weight and tire shake is what I think is the biggest factor on axles. My car is pretty light and I couldn't tell you how old the axles in it are. 30 spline and I think they might be Henry's axles if anyone remembers them. Zero spline twist and very little wear on the splines themselves. I couldn't even imagine the thousands of passes on them. I don't recommend anyone do what I do but I will just keep looking at them occasionally and someday I will probably retire racing before I buy new ones.

I'm easier on them now as mostly footbraking anywhere from 1.23-1.40 60' depending on if I leave in low or high with a fair bit of transbrake launches for 6.0 index. Good luck on whichever you choose.

eric,no need to get bigger axles,stick w/Mosers.I had 35 spline Mosers in my Beretta,went 1.05 60s,never a problem.I asked them about moving up to 40 spline said if I could run on 1 axle I couldn't hurt it!

40 spline if you never wanna buy axles again. 35 spline if you're fighting for every bit of et. You don't need 40 spline but I didn't need a chunk rated for 2,000hp for the 9" I run in my Nova either, 35 spline with a sbc.

Or how about this 35 spline if you buy Mark Williams. That'll get ya back in the last set of axles you ever buy territory. That's an objective opinion, evidenced by the fact I run Strange.

1. Mark Williams
2. Strange
3. Moser

Well I am pretty sure he isn't getting 40 spline in there.

I only suggested 40 spline if he was going to spend the money to upgrade from 33, not that he needs 40 spline which he dont.

12 bolt spoils are thin in the area where the bearing press on and have been known to crack and break. Max used to be 33 spline but now 35 spline are available but I’m leery of them.
I’d stick with 33 spline..

I don’t have any experience using Moser axles but do use Mark Williams 40 spline light weight rifle drilled axles. I broke a 35 spline axle that had more than 1000 runs on them in a hard hitting S/G, S/C door car, this is an area where I believe in “over kill”. In your case the 35’s will last a very long time. If you are going to change why not pay a few extra dollars and have them rifle drilled, there’s no down side but an up side when you decide to sell the car.

Depend on the application.

I have had 35 spline Mark Williams spool and axle for many years in my slow door car. I have broken it twice and it never hurt the spool either time.

We had a Strange 9" with a 12 bolt center in a dragster and it used to break the ring and pinion every couple hundred runs. Every time it broke, it banged the spool where it had to be replaced, the runout was that bad.

I forget about mark williams stuff- their spools are splined in a different area than Strange or Moser, and MW has offered 35 spline 12 bolt stuff for years. My mistake there!! I’ve always used Moser because they sponser a lot of our races, and I’ve not once had any trouble with Moser stuff but have seen several fellow racers break 12 bolt spools.
