Im still in awe how in how you broke those. At pretty much the strongest point. This truthfully shows how much stronger the ARB makes the R180! Also shows traction wasnt an issue! I know they are pricey but have you thought of upgrading to those RCV axles?
I think the RCV shafts will move the weak point to the stub shaft in the diff and possibly cause case failure. Replacing the half shafts will be much cheaper as long as everyone keeps doing Titan swaps.
I'll just keep a few spares on hand along with oil seals.
