OZISENS 3500 lb Trailer Hub Kit 5 on 4.5" Galvanized for #84 Tapered Spindles — Preassembled, Pre-lubed

OZISENS 3500lb 5-bolt 4.5" galvanized hub kit is a ready-to-install trailer hub assembly engineered for #84 tapered EZ-Lube spindles, supplying bearings, seals and hardware for immediate installation.

This complete hub kit is built for light- to medium-duty trailers that require a 3500 lb idler hub with a 5 on 4.5" bolt pattern and compatibility with #84 tapered spindles (1-1/16" to 1-3/8" inner spindle sizes). The hubs arrive pre-lubricated and pre-assembled with inner and outer bearings, grease seals, dust caps and all mounting hardware, and the hot-dip galvanized finish enhances corrosion resistance for longer service life, especially in wet or salt-exposed environments.

How do I confirm this hub fits my trailer spindle?

Measure your spindle and match the bearing and seal inner diameters to ensure compatibility. This kit accepts L44649 (1-1/16" ID) inner bearings and L68149 (1-3/8" ID) outer bearings, and it is designed for tapered #84 EZ-Lube spindles only.

• Verify spindle type: must be #84 tapered (not straight spindles).
• Check bearing IDs: 1-1/16" (L44649) and 1-3/8" (L68149).
• Seal ID: 1.719" grease seal fitted in the kit.
• Bolt pattern: 5 on 4.5"; hub length 6.34", height 4".

What components are included and how are they prepared?

The kit contains two complete galvanized hubs plus a full set of bearings, seals, nuts and installation hardware. Bearings and grease seals are factory pre-assembled and lubricated to reduce preparation time at installation.

• 2 galvanized hubs (3500 lb rating) and 2 dust caps.
• 2 L44649 and 2 L68149 bearings, pre-lubed and protected with plastic caps.
• 2 grease seals (1.719" I.D.), 2 spindle nuts, washers, cotter pins and 10 lug nuts (1/2"-20).
• 2 rubber plugs for dust cap openings and protective packaging.

How does the galvanized finish help my trailer over time?

Hot-dip galvanizing offers a thicker, more durable zinc coating than standard spray paint, improving resistance to moisture and salt and reducing rust formation. This extends usable life in marine, winter-road and humid conditions.

• Thicker zinc layer for enhanced corrosion protection.
• Improved longevity compared with painted hubs.
• Better protection for bearings and mating surfaces over time.
• Minimal maintenance: inspect seals and repack if necessary.

What should I expect during delivery and installation?

Items arrive well-packaged in a sturdy box with bubble wrap to prevent deformation; bearings and seals remain sealed in plastic caps. The pre-assembled and pre-lubricated state lets you install hubs quickly, following standard torque and cotter pin safety practices.

• Neatly boxed with bubble wrap for protection in transit.
• Bearing assemblies sealed to prevent grease leakage.
• All mounting hardware included for straightforward installation.
• Follow torque specifications and safety checks when mounting.

Who is this for: This OZISENS hub kit is designed for trailer owners, DIY mechanics and fleet operators who need a reliable, corrosion-resistant replacement hub for 3500 lb trailers with #84 tapered spindles. It’s especially suitable for users who value quick installation and long-term durability in coastal, winter or high-humidity environments; be sure to confirm spindle type and bearing IDs before ordering.
