LUXTRKSTO 2Sets Galvanized Trailer Idler Hub Kits

Best for high-coverage corrosion resistance. These hubs fit 5 on 4.5″ axles with a 1-1/16″ to 1-3/8″ #84 tapered spindle and arrive with bearings and grease seals pre-installed. The hot-dip galvanized surface offers superior resistance to seawater and wet environments, potentially extending service life compared to spray-painted finishes. Suitable for boaters frequently near saltwater or inland waters with splashing spray.
Selection rationale: Pre-installed bearings reduce installation time. Cautions: Not compatible with straight spindles or D-shaped grooves. Use only with matched 84-spindle configurations; verify spindle shape before purchase.

Buying Guide
What to consider when choosing stainless or galvanized trailer hubs:
- Spindle compatibility: Confirm your axle spindle type (tapered #84 vs straight) and the correct inner/outer bearing sizes (L44649/L68149).
- Hub size and bolt pattern: Most 3500-lb trailers use 5 on 4.5″ hubs; verify the lug count and bolt circle for your wheel.
- Material protection: Hot-dip galvanized finishes offer superior corrosion resistance in wet or salty environments compared with sprayed coatings.
- Pre-assembly benefits: Pre-installed bearings and grease seals save installation time but ensure exact fit for your spindle and bearings.
- Packaging and handling: Some kits use double-box or reinforced packaging to protect components during transport.
- Maintenance needs: Consider whether you prefer a kit with reusable grease seals or one that requires lubricating after installation.
