iBroPrat Trailer Bearing Kit for 3,500 lb Axles — 4 Sets (#84 spindles) Complete 40-piece with Bearings, Seals & Hardware

This iBroPrat kit supplies four full axle sets of bearings, races, seals and hardware so you can rebuild or maintain up to four hubs without hunting parts individually. Designed for common 3,500 lb trailer and boat hub assemblies, the package groups matched bearing sizes L68149 and L44649 with corresponding races, grease seals, dust caps, spindle nuts and small hardware.

How do I know this kit fits my trailer spindle?

Verify your spindle is a #84 style and measures between 1-1/16" and 1-3/8" across the journal. The kit contains the standard bearing pairs (L68149 inner, L44649 outer) and matching races for most 3,500 lb hubs that use those numbers.

• Fits 1-1/16" to 1-3/8" trailer axles (standard #84 spindle)
• Designed for 3,500 lb axle-rated trailer hubs
• Includes L68149 and L44649 bearing pairs and corresponding races
• Check existing bearing numbers or measure spindle journal for confirmation

What parts are included and why is it better than buying single pieces?

This luxury kit bundles four complete sets—40 parts total—so you get bearings, races, seals, caps and mounting hardware in matched quantities. Buying a full kit reduces compatibility issues and saves time and money versus sourcing individual items locally.

• 4× L68149 inner bearings and 4× matching races (L68111)
• 4× L44649 outer bearings and 4× matching races (L44610)
• 4× double-lip grease seals (171255TB), 4× dust caps, rubber plugs, spindle nuts, washers, cotter pins
• Extra shims and spare parts included for on-trailer adjustments and reserves

How durable and serviceable are these components?

Components are produced with precision-bearing manufacturing standards for consistent fit and reduced operating noise. Seals use a double-lip design to limit grease loss and keep contaminants out, and the set’s metal parts are heavyweight for longer service life.

• Precision bearings and matched races for reliable fit
• Double-lip grease seals to limit leaks and contamination
• Robust metal dust caps, spindle nuts, and washers included
• Packaged with protective bubble wrap to prevent shipping damage

What tools or skills do I need to install these bearings and hardware?

Basic mechanical skills and common trailer tools are sufficient for most installations: lug wrench, socket set, bearing packer or grease gun, seal driver, and torque wrench. If you aren’t comfortable working on hubs, a professional trailer shop can install the kit quickly using standard procedures.

• Typical tools: jack, stands, socket set, socket for spindle nut, torque wrench
• Optional tools: bearing packer, seal driver, punch for cotter pin removal
• Follow manufacturer torque specs and bearing preload procedures
• Professional installation available if you prefer not to DIY

Who is this kit for? iBroPrat’s 4-set 3500 lb bearing kit is ideal for boat owners, small trailer operators and repair shops who want matched bearings and hardware for multiple hubs. If you maintain one trailer and like to keep spares, or you operate a fleet of trailers that use #84 spindles, this bundle delivers convenience, parts compatibility and cost savings compared to buying each component separately. The kit also suits anyone prepping trailers for seasonal storage or routine preventative maintenance.
