2 Sets Trailer Hub Kit 5 Lug 4.5 in - Durable 3500 lb Trailer Hubs

In this review the 2 Sets Trailer Hub Kit 5 Lug 4.5 in is evaluated for boat and utility trailer owners who need a reliable, ready-to-install hub assembly for 3500 lb axles. The biggest reason to consider this kit is that it arrives as a nearly complete package with pre-lubricated bearings, dust caps and spare hardware, saving time and guesswork during installation. The reviewer found it particularly useful for replacing worn hubs on #84 spindles and appreciated the compatibility with common axle makes.

Key Features

• Spindle fitment: Designed to fit #84 spindles with tapered bearings L44649 outer and L68149 inner, ensuring correct fit on compatible axles.
• Durable construction: Gray cast iron hubs meet U.S. G3000 standard for strength and heat transfer, which helps with long term reliability under trailer loads.
• Corrosion resistance: Silver finish and 96-hour salt spray tested coating improve resistance to rust for trailers used near water.
• Complete kit: Includes 2 hubs, bearings, lug nuts, castle nuts, seals, cotter pins, dust caps and spare parts so the assembly is ready to mount out of the box.
• Pre-lubricated bearings: Bearings arrive pre-lubricated to simplify initial installation and reduce the chance of user error during first assembly.

Who It's For

This hub kit is aimed at owners of small boat trailers, utility trailers and replacement projects that use a 3500 lb rated axle with 5 on 4.5 in bolt pattern and #84 spindles. It suits DIY mechanics and small shops that value a complete kit that minimizes trips to the parts store.

Those who should look elsewhere include owners of nonstandard spindles or trailers with different bolt patterns, and anyone who needs hubs for ratings above 3500 lb; the kit is specific to the listed bearings and spindle sizes.
