Evaluation & Recommendation

This hub kit is a great fit for trailer owners running classic Toyota or Datsun 4-stud wheels on a 39-40mm axle, especially if you’re looking for a simple non-braked solution. It’s perfect for:

• Small utility trailers
• Boat trailers (under 750kg)
• Box trailers for local towing
• DIY trailer builds and retrofits

If you’re running a heavier trailer or need a braking system, this hub won’t meet those requirements — contact us and we’ll help you match a braked hub with the right rating.

Installation Tips:

1. Clean axle thoroughly before fitting.
2. Grease bearings properly using high-temp bearing grease.
3. Tap dust cap into place evenly — don’t hammer it directly.
4. Test spin and play before driving.
