| VP Currie Rock Jock pinion bearing size?
As far as I can tell, the pinion bearing size is 11mm. I am just comparing the SSD diamond axle to the rock jock and am slightly disappointed if that is the case. Guess I need to decide if the high pinion will be worth the machine work required to get the rock jock to a 13mm pinion bearing?

It's standard size. I don't think there's enough meat for a 13mm outer bearing but the inner pocket has been bored before.

Glad they're listening to their customers and finally over sizing their bearings

At least visually (via pics on the internet) it looks like this is the only axle I would consider to be a high pinion. Anyone know of others? I am assuming that because these gears are bevel cut vs spiral, going to a high pinion does not require finding a reverse cut ring and pinion gearset. Last edited by YeeP; 12-05-2015 at 06:41 PM. |

It's not high pinion and it is 5x11x4 bearings. I run a 5x11x5 on the outside to ensure good gear mesh.

Not on the rock jocks but I understand that the new F9 Curries do.

The stock axial gears are bevel cut. The HD gears are helical cut for more strength due to increased tooth contact. Screamer is correct that the currie housing is not high pinion. | |

Ya, the only way to get a true high pinion setup is to use a hypoid ring and pinion configuration. I know in 1:1, hypoid gears are super super finicky and also cause massive amounts of heat and torque twist; I don't know if that would translate to RC though. Hypoid gears can be informally thought of as a cross between a helical and worm gears. |

Yup, most of the time we just rotate the pinion upwards for a similar effect . Most front axles have adjustable c-hubs so you can get castor back in check. | |
