6 Lug Hub Complete Rebuild Kit 411-7504

6 Lug Hub Service Kit

The 6 Lug Hub Complete Rebuild Kit 411-7504 is a replacement service kit used for compatible EZ Loader boat trailer 6-lug hub assemblies. This kit is designed to help rebuild select 6-lug trailer hubs used in grease or oil bath hub configurations.

Hub service parts are important because the bearings, seals, and related hub components carry the trailer load while also dealing with road heat, water exposure, ramp use, and repeated towing. When these parts wear, leak, or become contaminated, the hub should be inspected and serviced before additional towing.

This kit is intended for compatible 6-lug EZ Loader trailer hub applications. Proper fitment matters because hub style, spindle size, bearing set, seal size, lubrication type, and wheel bolt pattern must match the trailer hub assembly.

6 Lug Hub Rebuild Kit Features

• Complete rebuild kit for compatible 6-lug EZ Loader trailer hubs
• Used for hub service on select grease or oil bath hub configurations
• Helps replace worn, leaking, damaged, or contaminated hub components
• Useful for preventive maintenance before long-distance towing
• Designed for compatible boat trailer hub service applications

Typical EZ Loader Trailer Applications

This kit is commonly used on compatible EZ Loader boat trailers equipped with 6-lug wheel hub assemblies. These hubs may be found on heavier trailer models where the running gear must support larger boats, higher loaded weight, and longer-distance towing.

Because EZ Loader hub assemblies can vary by model, year, axle rating, spindle size, and lubrication type, confirm your existing hub before ordering this rebuild kit.

Grease Hub vs. Oil Bath Hub Service

Some 6-lug trailer hubs use grease-packed bearings, while others use oil bath lubrication. The rebuild process and related service parts may differ depending on the hub style.

Before ordering, confirm whether your trailer hub uses grease, oil bath lubricant, a clear oil cap, a grease cap, or another hub configuration. If the hub oil appears milky, the grease is contaminated, or the seal area is leaking, the hub should be inspected before towing.

Installation Considerations

• Confirm the hub is a compatible 6-lug trailer hub before disassembly.
• Inspect the spindle, hub bore, bearing races, seal surface, hub cap, and wheel studs before reassembly.
• Replace damaged or contaminated hub components before towing.
• Use the correct lubricant for your hub style: grease or oil bath lubricant as required.
• Do not mix incompatible lubricants or reuse questionable seals.
• After service, check wheel end play, hub temperature, and lubricant condition before long-distance towing.

Real-World Insight

A trailer hub rebuild is usually needed because of water intrusion, worn bearings, leaking seals, heat damage, corrosion, or neglected maintenance. If a hub has been run hot, contaminated with water, or towed with failing bearings, inspect the spindle and hub carefully before installing new service parts. Rebuilding the hub correctly helps protect the wheel, bearings, spindle, tire, and trailer during towing.
