LUXTRKSTO Trailer Hub Kit 5x4.5 — 3500 lb pre-lubricated hubs for 1-1/16"–1-3/8" tapered spindles

LUXTRKSTO's 5x4.5 trailer hub kit is a complete, pre-lubricated 3500 lb hub assembly engineered to fit 1-1/16" to 1-3/8" tapered spindles and includes bearings, seals, nuts, dust caps and hardware for fast replacement.

This hub kit is built for light-duty trailers that require a reliable 3500 lb hub assembly in a 5 on 4.5" bolt pattern. The set arrives ready to mount — bearings are pre-greased and many parts are pre-installed — so you can replace worn hubs with minimal disassembly and little extra tooling. Constructed from heavy-duty carbon steel with corrosion-resistant surface treatment and compliant with US G3000 standards, the kit is sized for common spindle dimensions and comes with matching inner/outer bearings.

How do I confirm this hub fits my axle?

Measure the bolt pattern and spindle diameter before ordering. The bolt pattern is 5 on 4.5" (measure from the outer edge of one lug hole to the center of the opposite hole). This kit is intended for tapered spindles from 1-1/16" to 1-3/8" and pairs with L44649 outer and L68149 inner bearings.

• Bolt pattern: 5 on 4.5"
• Spindle compatibility: 1-1/16" to 1-3/8" tapered axles
• Bearing codes: L44649 (outer), L68149 (inner)
• Weight rating: 3500 lb per hub

What comes in the kit and what needs no extra parts?

The kit includes every common component needed to mount two hubs so you don’t have to buy separate hardware. It delivers hubs, bearings, seals, spindle nuts, washers, dust caps, lug nuts and cotter pins — everything organized to streamline a same-day repair or replacement.

• 2 hubs rated 3500 lb each
• 2 inner bearings (L68149) and 2 outer bearings (L44649)
• 2 grease seals (1.719" I.D. - 2.565" O.D.) and pre-lubricated bearings
• 2 spindle nuts, 2 washers, 2 dust caps with rubber plugs, 10 lug nuts and 2 cotter pins

Is installation difficult and what tools are required?

Installation is straightforward for someone with basic trailer maintenance experience. Most components arrive pre-assembled or pre-lubricated so you’ll typically need hand tools, a torque wrench, and a grinder to taper the dust cap edge as required for a snug fit on some spindles.

• Common tools: socket set, torque wrench, hammer, pliers
• Minor prep: grind dust cap OD to a taper if needed
• Pre-lubricated bearings reduce initial greasing time
• Follow torque specs and cotter pin installation for safety

How durable is the hub and what protection does it offer?

Hubs are formed from high-quality carbon steel and receive a protective surface coating to resist rust and corrosion. Bearings are precision-made for low friction and noise, and the thick grease seals reduce the chance of leakage during normal use.

• Material: heavy-duty carbon steel construction
• Surface finish: corrosion-resistant paint/treatment
• Seals: thick grease seals to minimize leaks
• Standard compliance: built to US G3000 guidelines

Who is this for? This LUXTRKSTO hub kit is aimed at trailer owners, DIY mechanics, fleet operators and service shops replacing worn hubs on small utility, boat, or equipment trailers rated for 3500 lb axles. It’s best for people who need a complete, ready-to-install solution that matches common tapered spindles and who value pre-lubricated bearings and included hardware to speed repairs. If you’re unsure about fitment, measure your bolt pattern and spindle diameter or consult a technician before purchase.
