If you've ever lost a weekend to trailer trouble, you know how important bearing protection is. The Vault system has a fully sealed, pressurized chamber that keeps out water and grit, and hybrid oil self-lubricates where it's needed.
You want to hit the road - or the boat ramp - without wondering if your trailer bearings will make it there and back. The Vault not only protects against water and road grit with its fully sealed system, it also uses a pressurized chamber filled with hybrid oil to keep things lubricated. As your bearings heat up, the oil thins and flows exactly where it's needed, keeping everything running cool and protected on every mile.
Whether you're hauling a boat, camper, or utility trailer, this kit is made to handle the pressure. It's sized for 4,200-lb and 5,200-lb Trailer Buddy axles and 2.328" hubs, so you know you're covered for the long haul.
No piecing together parts or running to the parts store. You get two Vault assemblies, O-rings, a Vault lube tube, installation tool, grease fitting, and Loctite. With everything included and clear instructions, even first-timers can tackle the upgrade with confidence.
