GREPSPUD 2 Sets Trailer Hub Kit — 5×4.5” for 3500 lbs

These hubs are designed for 3500-lb trailers with 1-1/16″ to 1-3/8″ tapered EZ-Lube spindles. The kit uses L44649 outer bearings and L68149 inner bearings and arrives pre-lubricated. The five-bolt pattern is measured from the outer edge of a hole to the center of the opposite hole. The kit is ideal for budget-conscious trailer owners needing a ready-to-install option. A potential caution: verify spindle shape and bolt pattern before purchase to avoid mismatches with straight spindles.
Who this is for: Boat and utility trailer owners replacing worn hubs on tapered spindles who want a complete, pre-lubricated solution with minimal assembly.
Why selected: Wide 5-bolt, pre-greased assembly, includes necessary hardware, fits common 3,500-lb spindles, and offers straightforward installation for quick repairs.
Caution: Not compatible with straight spindles; confirm the spindle type and bearing sizing prior to ordering to avoid delays.
What’s included and how it helps
- Pre-assembled bearings and seals
- All required installation parts
- Pre-lubricated components to reduce leak risk
GREPSPUD Galvanized Trailer Hub Kit — 5×4.5” for 3500 lbs

This galvanized option mirrors the standard GREPSPUD kit but adds a corrosion-resistant finish suitable for marine environments. It includes the EZ-Lube spindle compatibility and pre-lubricated bearings (L44649/L68149). The size guidance remains the same: check the five-bolt pattern and ensure the 1-1/16″ to 1-3/8″ spindle matches your axle. Best for trailers exposed to moisture or saltwater, where rust resistance is a priority. A limitation is the need to confirm actual galvanization integrity if used in harsh, salt-laden conditions over time.
Best for: Boat trailers parked near saltwater or frequent exposure to wet conditions where rust resistance matters.
Best-fit notes
- Galvanized finish enhances longevity in harsh environments
- Pre-lubricated components reduce maintenance time

Buying Guide: Key Considerations for Pre-Greased Trailer Hubs
- Spindle compatibility: Ensure your axle uses 1-1/16″ to 1-3/8″ EZ-Lube spindles and confirm whether you have tapered or straight spindles. The listed products target tapered 84-spindle configurations.
- Bearing compatibility: Most kits include L44649 outer and L68149 inner bearings. Verify your existing bearings match these codes for a smooth swap.
- Bolt pattern and hub dimensions: Commonly 5×4.5″ with a specific bolt-hole-to-hole measurement. Measure the pattern and length before purchase to avoid improper fit.
- Pre-lubrication vs. post-install lubrication: Pre-lubricated hubs save time and reduce maintenance but confirm seals’ quality to prevent grease leakage under use.
- Corrosion resistance: Galvanized finishes offer superior resistance in marine or humid environments. Consider galvanized options for boats and saltwater exposure.
- Installation readiness: Kits that include all hardware (nuts, washers, cotter pins, and caps) simplify installation and reduce trips to the hardware store.
- Packaging and storage: Proper packaging helps prevent contamination and damage during shipping and storage; some brands emphasize anti-collision packaging.
Frequently Asked Questions
- What does “pre-greased” mean for trailer hubs? It means the bearings and seals come pre-lubricated with grease, allowing immediate installation with reduced maintenance.
- Can I mix hub brands on the same axle? Mixing brands may lead to mismatched bearings, seals, and bolt patterns. Use the same model or ensure precise compatibility across bearings and spindles.
- How do I confirm the bolt pattern/bolt-hole spacing? Measure from the outer edge of one bolt hole to the center of the opposite hole; this is typically shown as 5×4.5″ for these kits.
- Are galvanized hubs worth the extra cost? For trailers exposed to moisture or saltwater, galvanized hubs offer better corrosion resistance and longevity.
- What if my spindle is straight instead of tapered? The listed kits are designed for tapered spindles; for straight spindles, look for kits explicitly labeled for straight spindles to avoid fit issues.
- Do these kits include all necessary installation hardware? Most kits include bearings, seals, nuts, cotter pins, grease caps, and necessary washers; verify the product page content before purchasing.
