A ready-to-install replacement brake hub for heavy-duty trailer and RV axles rated to 7,000 lbs. Bearing cones, seals, and grease are pre-installed at the factory -- no bench pressing, no guesswork. Matches Lippert and compatible OEM axle assemblies with the 8 on 6.5-inch bolt pattern common on fifth wheels, travel trailers, and gooseneck trailers.
The Lippert 814203 (vendor part 08-7937) is engineered as a direct replacement for worn or damaged brake hubs on 7,000 lb trailer axles. The hub arrives fully assembled -- bearing cones pressed in, grease seals installed, and packed with grease -- so installation comes down to cleaning the spindle, sliding the hub on, and torquing the castle nut. No special tools or press work required on the job site.
The solid iron construction delivers the strength and heat dissipation needed for repeated braking on heavy trailers. The 8-lug, 6.5-inch bolt circle is a widely used pattern on larger RV and commercial trailer applications, giving this hub broad cross-platform fitment across Lippert axle families and many compatible aftermarket axles.
Bearing cones, seals, and grease are factory-installed. Mount and torque -- no additional prep needed before installation.
Durable cast iron hub withstands heavy load cycles and provides reliable heat management during extended braking.
Matches the standard heavy-trailer 8-lug bolt circle. Compatible with 16-inch to 17.5-inch wheels using 1/2-inch lug nuts.
Rated for axles up to 7,000 lbs. Correct for single-axle heavy trailers or one end of a tandem 14,000 lb setup.
This hub is designed for use on 7,000 lb rated trailer axles using the 8 on 6.5-inch (203 mm) bolt pattern. This bolt pattern is common on:
The 8 on 6.5-inch bolt pattern with 1/2-inch studs is compatible with 16-inch and 17.5-inch trailer wheels using standard 1/2-inch-20 lug nuts. Always verify your wheel's center bore (hub-centric fit) and lug seat style before swapping hubs. Most trailer wheels in this size range use a conical (tapered) lug seat -- confirm your wheel matches before installing.
Hub replacement on a trailer axle follows a standard procedure. Always chock wheels, support the trailer on rated jack stands, and use a torque wrench for the final castle nut setting.
