Applications

Tech Note 1: Dualmatic,  Selectro, and Power Train 
Dualmatic was originally a Colorado based manufacturer who originally produced a lockout hub that was engaged by flipping 2 levers. In the mid 1970's, Dualmatic introduced a new, spring-lock hub design that featured a large, easy to turn control knob. Dualmatic produced hubs under the Dualmatic, Selectro, and Dana-Spicer Power Train brands. For a given application, the hubs were identical except for the name cast on the control knob face. Dualmatic would provide several hub models to original equipment manufacturers including Chrysler (1980-1990) and Rockwell, but in the 1990's, hub sales slowed and the hub manufacturing rights were sold by Dualmatic's parent company. Currently, several models of hubs are still available under the Selectro brand name. For identical applications, Selectro replacement parts and assemblies are totally interchangeable with large handle hubs branded Dualmatic, Selectro, or Power Train. 

Tech Note 2: Fits
The only original equipment hub we know this o-ring fits is the Dualmatic hubs used on 1980-1990 Dodge Dana 60 front axles with 8 Bolt Hub Locks. Most Dualmatic or Selectro and all Powertrain hubs were sold as aftermarket replacement hubs for other applications. See our application list below.

Tech Note 3: Lubricate
Before installing your new o-ring in the hub body groove, lubricate it with a THIN film of clean grease.
