LUXTRKSTO Trailer Idler Hub Kits 2-Set 5 on 4.5" 3,500 lb Galvanized Pre-Greased with Bearings

LUXTRKSTO 2Sets 5 Bolt 4.5" Trailer Idler Hub Kits are complete, hot-dip galvanized, pre-greased replacement hubs engineered to fit 3,500 lb round axles (5 on 4-1/2" bolt pattern) and arrive ready to install.

These idler hub kits include everything needed to refresh or replace the hubs on tandem or single-axle trailers rated for 3,500 lb axles. Each kit pairs galvanized hubs with pre-installed bearings and grease seals, NLGI2 grease, and a full complement of fasteners and accessories so you avoid sourcing multiple parts. The corrosion-resistant finish and high-quality bearing components are intended for trailers that see wet or salty conditions and for DIY mechanics who want a straightforward swap.

Will these hubs fit my trailer axle?

The LUXTRKSTO kits are designed for 5 on 4-1/2" bolt pattern wheels and 3,500 lb axles with round spindle diameters from 1-1/16" to 1-3/8". They are not compatible with D-shaped or grooved spindles. Verify your wheel bolt pattern and spindle type before ordering.

• Correct bolt pattern: 5 on 4-1/2"
• Axle rating: 3,500 lb (#84 hub style)
• Spindle compatibility: round spindles 1-1/16"–1-3/8"
• Not for D-shaped or grooved spindles

How do these hubs arrive and what’s pre-installed?

Each hub arrives hot-dip galvanized with bearings and grease seals already installed; hubs are pre-lubricated with NLGI2-grade grease. That reduces install time and keeps the correct lubrication and seal orientation in place from the start.

• Bearings and NBR double-lip seals pre-installed
• Pre-filled with NLGI2 grease for high adhesion and water resistance
• Included hardware: lug nuts, shaft nuts, washers, cotter pins, dust caps, rubber plugs
• Galvanized nuts and washers for added corrosion protection

What materials and standards are the components made to?

Hubs meet U.S. G3000 specifications and are made from high-quality carbon steel; bearings use precision bearing steel for low noise and heat. Seals are NBR rubber with a double-lip design to reduce leakage and contamination.

• Hub material: carbon steel, hot-dip galvanized finish
• Bearing material: high-grade bearing steel for accuracy
• Seal material: NBR double-lip grease seal
• Grease: NLGI2 grade with high-temperature stability and water resistance

What comes in the package and what tools will I need?

The two-set package supplies two complete idler hubs and a full set of installation hardware so you can replace both sides without hunting parts. Basic wheel-bearing and axle tools are required for installation; consider a torque wrench and bearing packer for best results.

• Included: 2 hubs, 2 outer L44649 bearings, 2 inner L68149 bearings
• Also included: 2 grease seals, 10 lug nuts, shaft nuts, washers, cotter pins
• Extras: 2 dust caps and 2 rubber plugs
• Recommended tools: torque wrench, socket set, bearing packer or grease gun

Who is this for: These LUXTRKSTO idler hub kits are aimed at trailer owners, fleet maintainers, and DIY mechanics looking to replace worn hubs on 3,500 lb round-spindle axles with a corrosion-resistant, ready-to-install solution. They suit boat trailers, utility trailers, campers, and other small trailers exposed to wet or salty environments where durable galvanization and pre-lubrication save time and reduce future maintenance needs.
