Lock Out Hubs

Locking hubs, also known as freewheeling hubs are an accessory fitted to many four-wheel drive vehicles allowing the front wheels to be disconnected from the front half shafts.

While in newer vechicles automatic hub locks are common, older vehicles used manual locking hubs to engage and disengage the front wheels.

Manual locking hubs from Mile Marker offer quality products made in the U.S.A. and feature a 1 year warranty.
