Vault Hubs

The VAULT "Hybrid Lubrication System" uses a semi-fluid oil in a pressurized chamber to give you the ultimate in wheel bearing lubication and protection. At ambient temperatures the oil is thick with a viscosity appoaching grease. As the bearing temperature rises during towing, the VAULT's Hybrid Oil thins out, replenishing the bearings with lubricant, and dissipating heat. No inspection, no maintenance and no service required.
