Trailer Hub Wheel Bearing Kit 4 Sets for 5200-6000 lb Tandem Axles

In this review the focus is on a complete trailer hub bearing kit designed for tandem axles rated 5200-6000 lb. The bottom line: this kit is for a trailer owner who needs a full, ready-to-install replacement set for both hubs and values solid materials and straightforward compatibility. It stands out because it bundles inner and outer bearings, races, two common grease seal sizes for D42 spindles, and all minor hardware so shops or DIYers can service both hubs without hunting parts.

Key Features

• Complete kit: Includes 4 inner bearings 25580 and 4 inner races 25520 so both hubs get matched internal components for reliable lubrication fitment.
• Outer bearing set: Comes with 4 outer bearings LM67048 and 4 outer races LM67010 which match common trailer hub tolerances for D42 spindles.
• Two grease seal options: Provides both 10-36 and 10-10 style seals to fit the D42 spindle and help prevent grease leakage under towing loads.
• Full hardware: Dust caps, rubber plugs, spindle nuts, cotter pins and washers are included so installation requires minimal extra parts.
• Durable materials: Bearings and races are made from alloy steel and use precision manufacturing to withstand marine and road exposure.

Who It's For

This kit is aimed at owners of trailers with 1.25 in to 1.75 in tandem axles rated between 5200 and 6000 lb who want a single purchase that covers both wheel hubs. It suits boat trailers, utility trailers, and anyone who prefers replacing bearings and seals in matched sets to reduce downtime.

It is less appropriate for someone who needs an individual bearing or an uncommon seal size not listed here, or for single-axle trailers outside the specified spindle fit; buyers should confirm their spindle is the D42 style before purchasing.

• Alloy steel construction and precision bearings provide durable, long-lasting performance under load.
