LUXTRKSTO 5x4.5 Trailer Hub Kit for 3500 lb Trailers — Tapered Axle 1-1/16"–1-3/8", Pre-greased Bearings

LUXTRKSTO 5x4.5 Trailer Hub Kit is a complete, pre-lubricated 3500 lb bearing-and-hub assembly built to fit 1-1/16" to 1-3/8" tapered axles with a 5 on 4.5" bolt pattern.

This hub kit provides everything needed to replace or upgrade trailer hubs on many single- or tandem-axle utility and boat trailers. Engineered from carbon steel with a protective finish, the assembly meets US G3000 quality standards and ships with bearings, seals, nuts, dust caps, and mounting hardware pre-installed or pre-lubricated to speed installation and reduce shop time.

How do I confirm this hub will fit my trailer?

Measure both your axle diameter and the bolt pattern before ordering. This LUXTRKSTO kit is intended for tapered axles from 1-1/16" to 1-3/8" and uses a five-bolt 4.5" (5 on 4.5") pattern. The kit accepts L44649 as the outer bearing and L68149 as the inner bearing—verify those part numbers match your existing setup.

• Measure axle diameter at bearing seating area (1-1/16"–1-3/8" supported).
• Measure bolt pattern from outermost point of one hole to center of another (5 on 4.5").
• Confirm bearing numbers L44649 (outer) and L68149 (inner) if replacing existing bearings.
• Contact support if you’re unsure before purchase to avoid delays.

What parts come in the kit and what’s pre-installed?

The LUXTRKSTO kit includes all hardware required for typical hub replacement—no extra trips to the parts store. Bearings arrive pre-lubricated and the hub assemblies have been prepared to reduce assembly time, so you can install and go.

• 2 x 3500 lb 5x4.5 hubs built for tapered axles.
• 2 x L68149 inner bearings and 2 x L44649 outer bearings, pre-greased.
• 2 grease seals (1.719" I.D - 2.565" O.D), 2 spindle nuts, washers, dust caps with rubber plugs.
• Fasteners: 10 nuts 1/2"-20 and 2 cotter pins (2.3" length) included.

How easy is installation and what tools or prep are required?

The hubs ship largely pre-assembled; you’ll only need common hand tools and a few minutes of spindle prep for a clean fit. The dust caps may require OD tapering at the leading edge—grinding a small bevel is recommended to ensure a snug seat.

• No bearing packing required—the bearings arrive pre-lubed for immediate assembly.
• Basic tools: torque wrench, socket set, hammer/drift for cotter pin seating, and a grinder for dust cap OD tapering if needed.
• Follow axle torque specs and cotter pin installation to secure spindle nuts properly.

What durability and maintenance features should I expect?

Constructed from high-quality carbon steel with a corrosion-resistant finish, this kit is designed for heavy-duty trailer use and lower maintenance. Pre-lubricated bearings, precision manufacturing, and a thick grease seal reduce wear and keep lubrication contained under normal conditions.

• Meets US G3000 standards for material and manufacturing consistency.
• Protective surface coating to limit rust and corrosion exposure.
• Thick grease seal and pre-lubed bearings for reduced friction and noise.
• 1-year limited guarantee covers defects—contact LUXTRKSTO support if issues arise.

Who is this for: This hub kit is aimed at trailer owners, repair shops, and DIY mechanics replacing hubs on 3500 lb-rated trailers with 1-1/16" to 1-3/8" tapered axles and a 5x4.5 bolt pattern. It’s a convenient option for anyone who wants a complete, pre-lubricated replacement that minimizes assembly time and includes all required fasteners and seals.
