Buying Guide
What to check before buying a 6 lug hub kit for a boat trailer
- Spindle type: Confirm your axle is a tapered EZ-Lube #42 spindle, not a straight spindle.
- Bolt pattern: Ensure the kit’s 6-bolt circle matches your wheel hub (5.5″ center-to-center).
- Bearing and seal compatibility: Look for 25580 inner bearings, 15123 outer bearings, and a 2.25″ ID grease seal.
- Lubrication status: Pre-lubed kits save time; if not, you’ll need to grease bearings during installation.
- Installation effort: Pre-installed bearing/seal kits reduce the required tools and labor.
- Environment and use: For saltwater boats, consider corrosion-resistant components and rust protection.
FAQ
- What is the benefit of a pre-lubricated hub kit?
It reduces installation time and ensures bearings are properly greased at setup. - How do I know if the hub kit fits my spindle?
Check spindle type (EZ-Lube #42) and ensure it is tapered, not straight. - What does a 6×5.5 bolt pattern mean?
Six bolts arranged on a 5.5-inch circle; measure from bolt hole center to opposite hole center. - Are these hubs suitable for saltwater trailers?
Most are, but verify corrosion resistance and seal quality for salt exposure. - Can I mix bearings from different brands?
Avoid mixing bearings and seals from different kits; use the same bearings specified to prevent fit issues. - What if my axle is 1-1/4″ to 1-3/4″ tapered?
All listed kits are designed for that range; confirm the exact measurement before ordering.
