ARB diff conversion

[Mack]

Hi chaps

I have a RD-03 10 spline and I need to convert it into a 24 spline (basically a RD-56). Anybody had the chance to do something similar?

thanks

All the parts you need are listed in the online arb manual which is here

No all 10 spline ARBs are convertable to 24,

only the "Late" 10 spline units, not earlier ones

So, fingers crossed ?

Whilst you can buy the parts to do it from ARB you will find it is cheaper to sell on the 10 spline and buy a new 24 spline unit. Been there done that.

Thanks guys.

The thing is that I got the 10 spline ARB by mistake and the seller (US) apparently did not bother at the end that I keep it. Have been trying to sell it here for a long time.....

The expensive part is the whole set of 6 gears. ARB do not sell just the 2 of them I need

I´ll ask aschroft just in case.

cheers

The parts list that ARB publish to upgrade the 10 spline locker (RD03), is to upgrade the diff to be the same as the 24 spline version (RD56).

It is possible to simply replace the side gears, or have the splines re-cut in 10 spline side gears. This is a cheaper option, but doesn't have the stronger housing of the RD56.

In Australia, people send their 10 spline side gears to Jack MacNamara for re-splining.
