I need a double keyed hub for my ATI balancer 918854. When I look out there some sites say 916032H is "double keyed" (i.e. BTR) but Summit's site says the 916032H has a single key vs 916032H2 is double keyed.

My guess is 916032M3 is the base hub, 916032H is a heat treated version of the base hub, and 916032H2 is a heat treated, double keyed version of the base hub.

Anyone know for sure the differences in the hubs?

The ATI website doesn't seem to differentiate between the numbers.

I just got off the phone with the tech line. Probably should have went there first but maybe this will help someone in the future.

916032M3 is the base steel hub that comes with the kit
916032H is the heat treated version of the base and only has 1 - 3/16" keyway
916032H2 is the heat treated version of the base and has 2 - 3/16" keyways

They also said they can double key any hub.
