Applications

Tech Note 1: Product Specs
QU50818 Bolt Circle is 3-3/4". Your matching 1-1/4" diameter axle shafts will 19 splines. The bolt thread is 3/8" coarse.

Tech Note 2: Threadlocker
Apply Blue Threadlocker to the bolt threads for maximum retention.

Tech Note 3: Wear
It is pretty common to find the bolt holes in a wheel hub are worn from loose bolts. It is also pretty common to have one or more rusted in bolts broken off flush with the wheel hub face. On most of these vintage wheel hubs, you can have a machine shop drill and tap 6 new bolt holes between the original holes. Bolting your new hub set to a wheel hub with damaged holes will just about guarantee you will have problems.

Tech Note 4: O-Rings, No Gaskets
QU50818 Hubs use factory installed o-rings instead of gaskets to seal between the lockout hub body and your wheel hub.
