2.5” Hub Operating Temp


Active Member
Anybody know the apx operating temp of a properly functioning hub? Do they ever get too hot to touch?

bump, iam curious also how hot they run. i know rearends can get hot if there pulling hard. hub temps are relative to brake heat also.


You can skip to 10:45 in this video. Banks was recording fluid temps in excess of 300 degrees during their dyno tests.

With enough time for the fluid to transfer its heat to the axle shafts I would say that yes, it's entirely possible for a hub to get so hot you wouldn't want to touch it.
