RV MURTS Trailer Brake Hub Drum Kit 5 on 4.5 - Durable 3500 lb Fit

In this review the RV MURTS Trailer Brake Hub Drum Kit is judged as a practical, budget-friendly replacement for owners of 3500 lb cargo and boat trailers using #84 spindles. The kit's single biggest selling point is its all-in-one convenience: a steel 5-bolt hub sized for 10' x 2-1/4' electric brakes that arrives with inner and outer bearings, a grease seal, castle nut, washer and cotter pin so installers can complete the swap without multiple trips to the parts store. For trailer owners who want a straightforward repair that fixes leaking or shaky spindles, this kit delivers.

Key Features

• Compatibility: Fits 5 bolt on 4.5 bolt pattern and 10' x 2-1/4' electric brake assemblies for 3500 lb trailer axles, so buyers can match it to common small trailer setups.
• Complete bearing kit: Includes inner and outer bearings and races (L44649, L68149 and related races) to restore proper bearing fitment and reduce play on the spindle.
• Double lip grease seal: The mild steel seal with NBR rubber lip improves resistance to water and dirt intrusion and helps stop persistent oil leaks.
• Repair hardware included: Castle nut, washer and cotter pin are supplied to finish the hub installation without missing parts.
• Sturdy hub construction: Prominent steel-made hub provides better support to the #84 spindle, designed to withstand wear and shear and reduce vibration and shaking once installed correctly.

Who It's For

The kit is aimed at DIY trailer owners, boaters and small cargo trailer operators who have a 3500 lb axle with a #84 1-3/8' to 1-1/16' spindle and need a quick, affordable hub replacement. It works well for anyone wanting to address leaking seals or a cracked spindle mounting surface by replacing the hub and bearings together.

It is less appropriate for heavy commercial trailers or uncommon bolt patterns and brake sizes; professionals working on custom or heavier axles should verify fitment and may prefer OEM-specific assemblies or heavier-duty components.

Pros & Cons

Pros

• Good fit and function for compatible trailers according to customer reports.
• Easy installation and the convenience of receiving bearings, seal and hardware in one package.
• Grease seal design reduces leaks and contamination compared with worn seals.

Cons

• Only suitable for specific 5 on 4.5 bolt pattern and #84 spindle sizes, so buyers must confirm fitment before ordering.
