GREPSPUD 2Sets Trailer Hub Kits 5 On 4.5
These 2-set hub kits are designed for 3500 lb trailers with 1-1/16″ to 1-3/8″ tapered axles (EZ-Lube #84 spindle). They include extra dust caps and rubber plugs, offering value-packed parts for quick repairs or spares. The kit specifies outer and inner bearing compatibility (L44649 and L68149) and grease seals with a 2.56″ outer diameter. The 5×4.5″ bolt pattern is standard among many boat and utility trailers. They come with pre-installed races and are ready for installation on compatible spindles.
Notes: Verify spindle type (tapered vs straight) and size before purchasing. The kit targets EZ-Lube axles and may not fit straight spindles. Users should check axle compatibility and reseal or replace dust caps as part of ongoing maintenance.
GREPSPUD 2 Sets Galvanized Trailer Hub Kits 5 on 4.5
Designed for 3500 lb trailers with 1-1/16″ to 1-3/8″ EZ-Lube #84 tapered axles, these pre-lubricated hubs come with L44649 outer and L68149 inner bearings. The kit emphasizes proper size verification (5×4.5″ bolt pattern) and includes necessary seals and plastic caps for leak prevention. The galvanized finish provides corrosion resistance, making them well-suited for saltwater or humid environments. Installation is streamlined since the bearings and seals arrive pre-assembled.
Consideration: Galvanized hardware withstands outdoor exposure, but ensure compatibility with existing components (axle length, dust cap size, and brake compatibility if applicable). This kit is best for users seeking a durable, low-maintenance option with ready-to-assemble parts.
Saree 2 Sets 3500lb Trailer Hub Kit 5 Bolt 4.5
These 2 sets from Saree are designed for 3500 lb trailers with 5×4.5″ bolt pattern and tapered spindles. The kit targets L44649 outer and L68149 inner bearings and includes pre-lubricated bearing assemblies, seals, and accompanying hardware. The packaging emphasizes independent box protection, helping minimize transit damage and simplify storage. They claim compatibility with popular brands like Dexter, AL-KO, Lippert, and others, ensuring broad fit for many aftermarket assemblies.
Usage note: Confirm spindle type (tapered vs straight) and bearing numbers before ordering. Pre-lubricated components reduce installation time, but proper torque and seal seating are still essential for a reliable seal and long service life.
iBroPrat 2Sets 3500Lb Trailer Idler Hub Kits
The iBroPrat kit targets 3,500 lb trailers with 1-1/16″ to 1-3/8″ tapered spindles and 5×4.5″ bolt patterns. The hubs come pre-installed with lubricated bearings and are sealed with plastic caps to prevent leakage. The kit provides guidance on measuring bolt pattern (Lug length A and D measurements) to ensure correct fit. This option is positioned as easy-to-install for DIY trailer maintenance and replacements.
Important: Ensure the bearing numbers match L44649 outer and L68149 inner families for your axle, and verify that your spindle is tapered rather than straight. Pre-assembly reduces labor, but correct seating and tightening remain critical for safety.
Fanmoss 2 Sets 3500Lb Trailer Hub Kits Assembly
Fanmoss offers 2-set hub kits for 3,500 lb trailer axles with 5×4.5″ bolt patterns and 1-1/16″ to 1-3/8″ tapered spindles. The kits are pre-assembled and lubricated, designed for RV, utility, and boat trailers. The hubs use rust-resistant carbon steel and high-quality bearings with leak-proof double-lip seals. They are marketed as a straightforward replacement solution with long service life and reduced maintenance needs.
Recommendations: Review the exact spindle dimensions and outer/inner bearing part numbers to avoid fit issues. If you regularly trailer in salty or humid climates, the galvanized or corrosion-resistant finishes may extend service life in these conditions.
Buying Guide: Key Purchase Considerations And Comparisons
When selecting boat trailer hubs, consider the following factors to ensure proper fit and durability:
- Spindle Type: Confirm whether your trailer uses a tapered (#84) spindle or a straight spindle. The hubs listed here are tailored to tapered spindles and may not fit straight spindles without adapters.
- Bolt Pattern and Size: Most fish, boat, and utility trailers use a 5×4.5″ bolt pattern. Measure the distance across the lug centers to verify compatibility with your wheels and hubs.
- Bearing Compatibility: Ensure the kit’s outer and inner bearings match your axle’s bearing numbers (commonly L44649 outer and L68149 inner for 1-1/16″ to 1-3/8″ spindles). Pre-lubrication helps installation, but correct bearing seating is essential for seal integrity.
- Pre-assembly And Lubrication: Kits that arrive pre-lubricated reduce installation time and maintenance. Verify that seals are compatible with your load and environment to prevent leaks and corrosion.
- Material And Finish: Galvanized hubs resist corrosion better in humid or salty environments. Painted or plain carbon steel hubs may require more frequent maintenance in such conditions.
- Included Hardware: Look for kits that include dust caps, seals, and lug nuts. Extra parts can be valuable for emergency repairs.
- Brand Compatibility: Some kits align with brands like Dexter, Al-Ko, Lippert, and Quality. If you own a branded axle assembly, confirm compatibility before purchasing.
- Packaging And Storage: Independent packaging and protective inner boxes help reduce transit damage and simplify storage, especially if you maintain multiple trailers.
Depth of options: The selections above emphasize 5×4.5″ bolt patterns with tapered spindles for 3500 lb trailers. For straight spindles or different axle ratings, explore alternate hub kits designed specifically for those configurations to avoid fit issues and maintain trailer safety.
