Does anyone have 33 or 35 spline axles and lockers? There's a company in town that can take an axle or cv and make it into any spline count you want. I did it with a set of 935 cv axles on my buggy. They were 33 spline and I make them into 35 spline. Is there an advantage to having axles and lockers with such high spline counts?

 

Uhhhh...what!?

How did they "make" 33 spline into 35 spline?

Unless they shortened them, you can't respline something.

Typically, the whole point of more splines is a larger axleshaft, when comparing the same axle.

 

35 splines on a factory 27 spline axle sounds like some redneck stuff that won't work. Plus where do you intend to get parts for it? Stick with stock or aftermarket upgrades with reparable companies like Yukon.

 

So are you saying it doesnt exist and that there's no need for them? I have seen spools on Trophy trucks that are 40 spline. Since spools are similar to lockers, why wouldnt you want more splines in a D30 and 8.25?

 

Trophy trucks have custom built axles with larger shafts. You wouldn't want more splines I'm the D30 and 8.25 because you wouldn't gain any strength and parts would be impossible to find.

 

Typically more splines equate to larger O.D. axles meaning more material and stronger. This isn't always the case. I thought this guy had a good example:

A D30 does have an upgrade available to 30 spline shafts, but thats not always the case per axle type. Your rear axle is likely limited or already at the highest spline count manufactured. That's where to look into chromoly shafts vs stock.

As far as your axles, imagine a stock shaft with No splines.
Now imagine it with 40 splines, now with 29 splines.
Same O.D. just a change in tooth count right... I'm sure somewhere in theres a certain spline count is optimal, likely stock.

This is where your larger shaft to axle corresponds to strength. D30, d44,d60, d80....

If I'm understanding your thinking, I fail to see how a 1" shaft is better off as 1" 30 spline vs 1" 40 spline or whatever. Sure there's an optimal spline-O.D.,
but thats typically where a bigger axle comes in, am I wrong folks?

I also don't disagree, somone could take an axle shaft and potentially spray weld/ machine it to any spline, but my god why pay the coin lol.

 

I would love to see a trophy truck with stock XJ axles lmao

 

I would love to see how far you could get it

 

As with what the others have said, I think you're getting spline count vs. actual shaft o.d. confused and equating the higher spline count with more strength. It's true, a 40 spline 1.5" od shaft will be stronger than a 29 spline 1" shaft, but the primary reason for that strength will be the increase in shaft diameter, not spline count.

 

First off, the only way I know to get that s;line count is with the Dana 44 rear. Yoiu can go with a supper D44 Detroit locker with 33 splines or ARB with 35 splines

 

Its a slow process but they use a broach to make 31 or 33 into 35. So what I had was a 935 cv, take it apart and have the center star broached from whatever spline it was to the 35 spline I wanted. That company Ayers Gear in Phoenix then made me a set of axles that are 1.5" in diameter, 35 spline. They told me just as everyone else on this thread has that O.D. plays a key role in how many splines you can have on an axle shaft. I wasn't thinking of that at the time I posted this thread. I kept reading different threads from everyone who was trying to build a stronger D30 or whatever and thought the splines could be more. But now I know and I appreciate everyone's input.

Ayers Gear did say that they have been asked to make bigger axles for the side by sides but when it comes to the cv stars they are having a difficult time re-splining those. Its the hardness of those materials, the rockwell, that's making it difficult to do and its destroying their tooling.
