The Dana Spicer 78944 (also listed as 078944) is a wheel bearing nut designed for on-highway axle applications. It threads to a 3.25-12UN-3B specification and accepts a 4.125-inch wrench flat for proper torquing during wheel-end service. Sourced directly from Dana Spicer, this nut is the correct factory replacement for hub and spindle nut positions where that thread form is specified. Call us to confirm proper fit for your axle configuration before ordering.
