iBroPrat 3500 lb Trailer Hub Bearing Kit, 2 Sets (20 pc) for #84 Spindle — Seals & Hardware

Complete replacement hub bearing kit for 3500 lb #84 trailer spindles — two full sets (20 pieces) including bearings, races, seals, dust caps, spindle nuts and hardware.

If you tow a small boat or utility trailer with a 3500 lb capacity and #84 spindle, these two iBroPrat bearing kits give you everything needed for immediate wheel-end service and a spare set for future repairs. The set fits axles from 1-1/16" to 1-3/8" and is packaged to protect delicate parts during shipping. Components are precision-made for smooth fit and long life, and the kit includes items often missing from cheaper alternatives like dust caps, rubber plugs and spindle nuts.

What parts are included in these two 20-piece kits?

Each of the two sets supplies the essential inner and outer bearings plus races and seals needed to rebuild one hub. iBroPrat bundles replacement hardware so you can finish the job without sourcing extra components.

• 2 × bearings L68149 and 2 × races L68111 (outer)
• 2 × bearings L44649 and 2 × races L44610 (inner)
• 2 × grease seals (171255TB, 1.719" I.D), 2 × dust caps (1.98"), 2 × spindle nuts
• 2 × cotter pins, 2 × rubber plugs, 2 × washers — total 20 pieces per two-set package

Which axles and spindles will this bearing kit fit?

The kit is designed for trailers using the 3500 lb capacity #84 spindle and works across common barrel diameters. Confirm your axle measures between 1-1/16" and 1-3/8" to ensure a correct fit.

• Fits 1-1/16" to 1-3/8" trailer axle diameters
• Suitable for 3500 lb (1,588 kg) #84 spindle applications
• Commonly used on boat trailers, utility trailers and light-duty enclosed trailers

How do these components perform and how are they protected?

iBroPrat bearings are manufactured to close tolerances for low operational noise and reliable seating within the hub. The seals feature a double-lip design to reduce grease loss and keep contaminants out, while packaging reduces transit damage.

• Precision-made bearings for smooth rotation and low noise
• Double-lip grease seals to minimize leakage and contamination
• Parts shipped in a heavy-duty box with bubble wrap to prevent in-transit damage

What extra hardware is supplied that other kits omit?

Unlike many economy kits, this iBroPrat offering includes dust caps, rubber plugs, spindle nuts and shims so you won’t have to run to the parts store mid-repair. Extras act as spares so you have backups if a piece is lost or damaged during installation.

• Dust caps (1.98") and rubber plugs included for sealing hub openings
• Spindle nuts and washers provided to complete the assembly
• Extra cotter pins and shims supplied for adjustment and spare use

Who is this for? This two-set iBroPrat kit is aimed at DIY trailer owners, boaters and fleet managers who need a full hub rebuild now and a complete spare set for later. It’s convenient for weekend mechanics, mobile trailer repair shops and anyone who prefers to carry replacement parts on the road. Verify your spindle type and axle diameter before ordering to ensure compatibility.
