Anti-collision packaging protects parts during transport, and the kit is designed to deliver reliable service life with good heat transfer and rigidity characteristics.
Buying Guide
When selecting a 5 lug hub assembly for a 3500 lb trailer, consider the following factors:
- Spindle type: Confirm whether your axle uses a tapered or straight spindle. Most 3500 lb applications use tapered spindles with #84 sizing and L44649/L68149 bearing pairings.
- Bolt pattern and capacity: Ensure the kit matches a 5×4.5″ bolt circle and supports up to 3500 lbs per axle. Mismatches can compromise braking, steering, and wheel retention.
- Bearings and seals: Verify bearing part numbers and seal dimensions to guarantee proper fit and lubrication retention. Correct seals prevent leaks and rust.
- Included components: Look for complete kits with bearings, caps, lug nuts, cotter pins, and dust caps to reduce additional shopping and compatibility issues.
- Packaging and storage: Dual or independent packaging helps prevent mix-ups during transport and makes long-term storage easier.
- Corrosion resistance: A protective coating or paint finish helps extend life in saltwater or humid environments common to boat trailers.
- Compatibility with brands: Some kits are designed to fit multiple brand axles (Dexter, Al-Ko, Lippert, etc.). Double-check compatibility with your specific trailer model.
- Installation ease: Pre-installed bearings or ready-to-mount components can significantly reduce installation time and the risk of improper bearing seating.
For installation guidance, refer to the manufacturer’s instructions included with each kit. Always verify torque specifications and use the appropriate grease and torque sequence to ensure safe operation and optimal bearing life.
