Trailer Hub Kit 5 Bolt 4.5 in for 3500 lbs - Durable Replacement

In this review the focus is on a single-purpose trailer hub kit designed for 3500 lb trailers, and the bottom line is clear: this kit is for DIYers and service shops that need a durable, ready-to-install replacement hub that fits #84 spindles. The reviewer found that the kit arrives with everything needed, including pre-lubricated tapered bearings and spare hardware, which makes installation straightforward. The combination of gray cast iron construction and a salt spray tested finish is the single biggest reason to consider this hub for routine trailer maintenance or axle rebuilds.

Key Features

• Fit for #84 spindles: The kit matches tapered bearings L44649 outer and L68149 inner to fit common 1-1/16 in and 1-3/8 in spindle dimensions for reliable alignment.
• 5 lug, 4.5 in bolt pattern: The hub is built for 5x4.5 bolt pattern and a 3500 lb axle rating, ensuring compatibility with many light- to medium-duty trailers.
• G3000 standard cast iron: Manufactured from gray cast iron to G3000 standards to provide rigidity and improved heat dissipation under load.
• Corrosion resistance: A silver coating passed a 96-hour salt spray test, helping the hub resist rust in marine and roadside environments.
• Complete installation kit: Ships with hub, L44649 and L68149 bearings, grease seal, castle nut, cotter pin, lug nuts, washer, plus two dust caps and two rubber plugs for convenience.
• Pre-lubricated bearings: Bearings arrive pre-greased to reduce initial assembly time and to help ensure correct lubrication at first use.

Who It's For

This hub kit suits trailer owners who perform their own maintenance, small repair shops, and boat trailer owners who need parts that resist saltwater corrosion. It is a practical option for anyone replacing worn hubs where a 3500 lb rating and 5x4.5 bolt pattern are required.

It is less appropriate for heavy commercial trailers that exceed 3500 lb per axle or for trailers that require a different bearing or bolt pattern; buyers should confirm spindle type (#84) and bearing sizes before ordering to avoid compatibility issues.

Pros & Cons

Pros

• Comes as an all-in-one kit so installers do not need to source multiple parts separately.
• Durable gray cast iron construction with tested corrosion resistance for longer service life.
• Pre-lubricated bearings and spare dust caps/plug parts speed up installation and add convenience.

Cons

• Intended specifically for #84 spindles and 5x4.5 bolt pattern, so it is not universal and requires verification before purchase.
