Thomletha Trailer Axle 2000 lbs (56.5″ Hub Face)

The 56.5″ hub-face Thomletha axle is designed for light trailers, including boat trailers. Best for: small to midsize boats and trailers that require a straightforward, cost-effective axle replacement. Why selected: offers solid 2,000-lb capacity and compatible mounting for common spring centers. Caution: verify spring mounting compatibility, as some setups require welding or custom brackets.
Getanye 2000 lbs Trailer Axle (49″ Hub Face)

Best for: smaller, lighter boats and compact trailers needing a compact axle with adequate capacity. Why selected: 2,000-lb rating in a shorter hub-face footprint suits small trailers. Caution: ensure your trailer frame width aligns with the 49″ hub-face measurement to avoid tire clearance issues.
Replacement for Trailer Axle (73″ Hub Face)

Best for: light-to-medium duty boats and utility trailers that require a longer hub-face and higher structural support. Why selected: heavy-duty rating up to 3,500 lbs with 73″ hub-face and 58″ spring center. Caution: spring mounts are shipped loose and must be welded or bolted per your setup.
Thomletha Trailer Axle 2000 lbs (60″ Hub Face)

Best for: mid-to-wide trailers that need flexibility with mounting. Why selected: 60″ hub-face provides a versatile fit for many trailer frames. Caution: installation brackets may require welding or custom fitting to your trailer design.
Sturdy Built Galvanized Boat Trailer Axle (84″ Hub Face)

Best for: larger small boats and longer wheelbases that need a robust, galvanized axle. Why selected: corrosion-resistant galvanized finish with an adjustable spring center range (66″ – 71.5″). Caution: longer hub-face requires wider trailer frame and potentially different tire clearance.
Buying Guide: Key Purchase Considerations
What hub-face measurement do I need?
Hub-face is the distance between the centers of the wheel hubs. Match your trailer’s wheel hubs and frame width to ensure proper tire alignment and mounting. If in doubt, choose a close-but-longer hub-face with adjustable spring centers rather than a tight fit that requires rework.
How important is spring-center length?
Spring-center length affects how the axle mounts to the trailer frame and where the leaf springs sit. A longer spring center provides more mounting options and can improve load distribution on longer trailers. Shorter centers are common on compact trailers and teardrop trailers.
What load capacity do I need?
For small boats and lightweight trailers, 2,000 lbs is usually sufficient. If you carry larger small boats or travel with gear, consider up to 3,500 lbs. Do not exceed the axle’s rated capacity to maintain trailer handling and safety.
What about installation and mounting?
Some axles ship with mounting brackets that require welding, while others offer bolt-on configurations. Plan for compatibility with your trailer frame, spring mounts, and the wheel hub bore. If brackets are shipped loose, have a professional weld-or-bolt plan in place.
Material and corrosion resistance matter.
Galvanized finishes resist saltwater exposure and moisture. If you trailer in coastal areas or frequent salt use, galvanized axles extend service life.
Are hub kits a better option than full axles?
Hub kits can be convenient for upgrading a trailer with existing axles, but ensure spindle diameter, bolt pattern, and hub dimensions match your frame. For new trailers, a complete axle simplifies alignment and mounting.
Frequently Asked Questions
- What is hub face, and why does it matter?
Hub face is the distance between the centers of the wheel hubs. It determines how far the tires sit from the trailer frame and affects wheel alignment and clearance.
- Can I mix hub faces on a single trailer?
Mixing hub faces on a single axle is not recommended due to alignment and tire clearance issues. Use axles designed for your trailer width and wheel size.
- Is a galvanized axle better for saltwater use?
Yes, galvanizing offers superior corrosion resistance, prolonging axle life in salty or humid environments.
- Do I need professional installation for trailer axles?
Installation can involve welding or precise bolt-up. If you lack experience, a professional installer ensures proper mounting and safety.
- What torque is required for hub mounting bolts?
Follow the manufacturer’s torque specs for the specific hub and spindle to avoid overtightening or loosening under use.
