OZISENS 3500lb Trailer Hub Kit 5-on-4.5 for #84 Tapered Axles — Pre-Lubricated, Complete Hardware

OZISENS 3500lb 5-on-4.5 pre-lubricated trailer hub kit is a ready-to-install hub assembly for #84 tapered (EZ-Lube) axles rated for 3,500 lb, including bearings, seals, nuts, washers, cotter pins, dust caps and grease.

This complete hub kit is built for small to medium trailers that use a 5x4.5 bolt pattern and a #84 tapered spindle (1-1/16" to 1-3/8"). OZISENS supplies pre-assembled L44649/L68149 bearings and 1.719" I.D. grease seals lubricated at the factory so you can replace worn idler hubs quickly. The hubs are carbon-steel with a protective black finish and shipped with all mounting hardware to simplify installation.

How do I confirm compatibility with my trailer axle?

Check your spindle and wheel measurements carefully before ordering. This kit fits EZ-Lube #84 tapered spindles (not straight spindles) and uses bearings L44649 (inner) and L68149 (outer).

• Bolt pattern: 5 on 4.5" (measure lug hole center-to-center)
• Seal I.D.: 1.719" (fits 1.72" grease seals)
• Bearing I.D.: L68149 outer bearing 1-3/8"
• Spindle range: 1-1/16" to 1-3/8" tapered #84 type

What parts are included and what are their dimensions?

The kit is comprehensive: two 3500 lb hubs, bearings, seals and the small hardware you need to mount them. Hubs are compact but robust, sized for common utility, boat, and cargo trailer wheels that use a 5x4.5 bolt circle.

• 2 hub assemblies (L: 6.34", H: 4") with 5x4.5 bolt pattern
• 2 L68149 bearings (I.D. 1-3/8") and pre-lubricated L44649 inner bearings
• 2 grease seals (I.D. 1.719") and 2 dust caps (O.D. 1.98")
• 10 lug nuts (1/2"-20), 2 spindle nuts (1" thread), washers, cotter pins, rubber plugs

How much assembly is required and what makes installation easier?

Minimal assembly is needed because key components arrive pre-assembled and greased. Bearings and seals are installed and sealed with protective caps, so you primarily mount the hub to the spindle, secure the spindle nut and cotter pin, and torque the lug nuts to spec.

• Bearings and seals pre-lubricated and sealed at the factory
• All hardware included—no extra sourcing required
• Bubble-wrapped and boxed to protect parts during shipping
• Comes with dust caps and rubber plugs for finishing touches

Will the hub resist corrosion and wear over time?

OZISENS uses carbon steel hubs with a black protective coating to slow corrosion and resist chips from road debris. Bearings are made from alloy bearing steel with low-wear characteristics and a double-lip grease seal to help prevent leakage under normal use.

• Black coated carbon-steel hub body for corrosion resistance
• High-quality bearings reduce vibration and noise
• Double-lip grease seal minimizes grease loss and contamination
• Pre-lubrication helps initial break-in and reduces immediate maintenance

Who is this for: This OZISENS hub kit is aimed at owners and service techs of light trailers—utility, boat, car haulers, and small equipment trailers—who need a direct-fit, ready-to-install replacement for worn idler hubs on #84 tapered EZ-Lube axles. It suits DIY mechanics and professional shops wanting a complete, pre-lubed hub assembly with all mounting parts included.
