Hi Guys,
Been racing vintage for a while now but only just joined the forum, and I some help so clear up the confusion I have on sorting out my Pro X project.
In the manual, the gearbox output gears are listed as SST-06 with SST-19 in brackets.
I appreciate info is a bit sketchy on these but I've scoured the net and can't find the answer.
What is the difference between SST-06 and SST-19?
I thought the 06 were aluminium and the 19 hardened, but the 19 look phyiscally bigger.
Any ideas please?

The 19s are for the Team Version and the 06s are for the Sport. I suspect, as you've said, the 19s are probably hardened or a more durable version of the Sport's gears.

SST-19 appears to be a hardened version of SST-6.

Maybe the SST-6 was included in the Pro-X kit, and the SST-19 was included in the Pro-XRT kit to deal with the higher loads of the truck drivetrain (while also being available as 'Team Upgrade' for the pro-x)...? Just speculation...

Thanks guys.

Hmm, don't know what I've got then. Labelled as SST-19 but they are definitely a larger diameter than the ones that are in the box.
Won't actually fit in the gearbox recess so they must be wrong.
I'm guessing they might actually be the Rampage Pro ones? SST-34. They look like they are bigger.
