Yes, in 3.73, 4.10, 4.56 and 4.88 ratios as special order for 81837 only, according to the HT Shop manual supplement.
Interestingly enough, none of the parts are in the parts manual, nor is the 3.36 10 bolt crown wheel and pinion.

These were a dealer supply only and not fitted on the assembly line I believe.

I think you might be right. It would seem to be a very rare option. I've only ever seen one, on a HT.

Correct abi, dealer fit option only on HK GTS327 and HT GTS350 manual. I've only ever seen one diff, and know of one NOS axle. Norm Beechey had one in his race car, and the Marathon cars had them too. They'd be very rare due to the cost, it was huge compared to the vehicle price. |

Dave Bennett's GTS327 ran a 13.61 according to Monaro magic, l gather it would have had a 12 bolt.

I also saw a nos axle back in the late 90's, possibly the same one! I did not take a close enough look so cant recall the difference's compared to the 28 spline std axle. 30 splines at the inner end but what about the rest, the 10 bolt axles usually break at the other end just inside the wheel bearing retaining ring. perhaps the metallurgy was better otherwise a racing tyre hopping ripple strips would be a problem I think. If anyone has pics of an axle or diff assy?

If anyone has pics of an axle or diff assy? They look just like a 10-bolt axle but with 30 splines. They wee built here, only the cast complete centre was imported. |

He ran it at Calder when it was 9 days old, running a 3.36 rear axle. Totally original down to the D70 tyres, only tuned properly and exhaust dropped. Ran 14.46, so with a bit more development and getting used to the car a 13.61 would be achievable. |

Anyone know how the tec of axles is cast, or about if right hand and left are different in any way in the casting process.
I think one should maybe not put a used axle that was working turning one way and then use it for going the other way, like if you snapped an axle on the right and you picked up another that came out from the left side.
And their was different markings on the centre hub I think to left and right and that makes me think just maybe it's true.
I know the length was the same for most holdens so they would fit both right and left and I would just use any axle years ago and found that the HQ banjo axles were the weakest of them all, I think because they were longer than the HK-T-G and the Toranas and that making them flex more, not to mention the rubbish 10 spline.
I would go find the 1 tonne axles for the big 10 bolt diff and they were machined down in a fashion, dropping in size not progressively but in a stage fashion, I wonder why.

The axles are hot forgings which are finish machined to size.
It is important to put used axles back on the side they came out of, as the splines take a "set" opposite to the thrust direction. You can often see it with the naked eye. The entire length of the axle similarly takes on a set, but it usually isn't visible.
Swapping sides reverses the set and accelerates fatigue failure at the point where the splines enter the drive spline in the diff centre. It's like bending any piece of metal backwards and forwards a few times.
For HKTG 10 bolt both axles are identical, and use the same part number for left and right hand side.
The axles are normally arranged so the major stress points, like the base of the drive splines, are arranged to be on a larger diameter than the main body of the axle. This places the main stress risers, like the base of the splines, outside the portion of the axle which operates in torsion. For the same reason all the cross sectional area changes are gradual, as are the graduations between machined diameters.
General rule of thumb is that you shouldn't see an abrupt diameter changes or sharp radii.
Have a look at a head bolt or rod bolt as an example.
