HD 24/32 Front Half Shafts

[chook73]

In the market for a pair of HD front half shafts and just wondering if anyone can recommend a good manufacturer. Unfortunately Ashcroft only supply 24/23 for use with their CV's.

Cheers

For those looking for these Barry at HiTough was more than helpful today and whilst his shafts aren't listed as HD that is because they narrow at the CV end and he doesn't want to give the wrong impression. They are still made from the HiTough material and will be stronger than the stock shafts which is exactly what I am looking for.

hy-tuf ;)

Copy that thank you.

Hi-Tough for the company, hy-tuf for the material :)

Is there a reason you have stuck with the OEM small CV's?

The portals come with 32 spline HD CV's and wolfgang isn't planning to make front shafts until later this year or early next.

Cheers, well I doubt he will be able to make them any stronger than Barry unless he goes to a better material. It's very possible but would push the price up.

I think it's more about completing the portal kit than trying to make the strongest axle. To be honest it would not surprise me if he reduced the number of splines to thicken the shaft as Ashcroft do.

The interesting thing talking to Barry yesterday is he doesn't claim hy-tuf to be the strongest material on the market but what he did claim is that it is the most hard wearing as whilst there are stronger materials they break after a certain number of cycles where as the hy-tuf keeps on going.

there are plenty on here that can explain this more accurately than me, but I will have a go.

There is UTS, Ultimate Tensile Strength, which material and heat treating, along with dia will determine.

Then there is the ability for the axle shaft to absord shock loads....you can have a very high UTS, but it may be "brittle"....

making the splines thicker is not what makes them stronger...LR have 10, 23, 24 and 32 spline....23 being the largest Dia. It is more about spline design. In the USA if you run a ford 9 you can by big arse 40 spline axles.

30 spline toyotas (larger than any LR shaft) are common, and 35 spline (bigger again) common in Ford 9 and Dana 60. The reason ashcroft go to a coarser spline is simply as its a LR standard aplication. If going to upgrade to a HD cv or shaft, it would be stupid to go with LR smallest weakest spline (32)...........

Really helpful thank you.

24 spline is larger than 23 spline.

And in reality 35 spline is not common with Dana 60s and I do not believe ever happened in a Ford 9". It is almost all aftermarket.

Yep my bad on the 24 vs 23 dis.

And I was just using the 35 spline as an example of more splines being stronger, ie its not the number of splines that determines the strength.....not them being stock. I bet though, there would be more 35 spline axles in the USA than aftermarket rover HD in Oz....
