Product Information

Full details

The Parnells Twin Axle Trailer Kit (EC7555) is an ideal solution for builders, farmers, and hobbyists looking to construct or refurbish a road-legal trailer with a 750kg capacity. This comprehensive package includes everything from high-speed wheels to ALKO hubs and a robust zinc-plated hitch, ensuring reliable performance for heavy-duty tasks. While the kit provides all essential hardware for assembly, users must ensure their trailer frame is properly engineered to handle the specific dimensions of the 35x35mm stub axles and 50x50mm hitch mounting point.

Extended Product Information

FAQs

Does this kit include everything needed for a trailer axle assembly?

Yes, it includes 4 wheels, 4 ALKO hubs, 4 stub axles, and a hitch, covering the core requirements for a twin axle trailer build.

Can I use this kit for an off-road trailer?

While designed for road-legal use, its robust construction makes it suitable for farm or off-road use, provided the frame is built to match the axle specifications.

What is the PCD of the hubs?

The hubs feature a standard 4-stud 100mm PCD.

Is the hitch adjustable?

The hitch is designed for a standard 50x50mm box section frame and is not adjustable beyond its fixed mounting dimensions.

How much weight can the entire trailer carry?

The kit is rated for a total weight capacity of 750kg.

Are the bearings serviceable?

The hubs feature high-speed sealed ball bearings, which are generally replaced rather than serviced.

Troubleshooting

Excessive trailer sway during towing

Check that the load is balanced correctly over the axles and verify that the stub axles are perfectly square to the frame.

Wheel hub running hot

Check for over-tightened axle nuts or failing bearings; ensure the trailer is not being consistently overloaded beyond its 750kg limit.

Hitch is difficult to operate

Apply a high-quality grease to the internal mechanism of the zinc-plated hitch to ensure all moving parts engage freely.

Pros and Cons

Pros

  • Complete "all-in-one" kit reduces the need for sourcing individual parts
  • High-speed sealed ball bearings require minimal maintenance
  • Compliance with international road regulations ensures safety and legality
  • Zinc-plated hitch provides excellent corrosion resistance
  • High individual load capacity per wheel provides a safety margin for the 750kg total limit

Cons

  • Requires professional fabrication or mechanical skills to install correctly
  • Specifically designed for 50x50mm box section frames, limiting versatility
  • Stub axles are fixed at 35x35mm, necessitating precise frame fitment

Setup, Compatibility & Care

Installation requires basic metal fabrication knowledge, specifically the ability to mount the 35x35mm stub axles squarely to your trailer frame. Ensure that the distance between the two axles is calculated to provide proper balance for your specific load type. The hitch is designed for a 50x50mm box section; verify your frame dimensions before attempting assembly.

Maintenance Tips:

  1. Periodically check the wheel nuts to ensure they remain torqued to specifications.
  2. Although the ball bearings are sealed for high-speed use, inspect them annually for signs of play or excessive heat after long journeys.
  3. Keep the hitch mechanism lubricated to ensure smooth coupling and decoupling.
  4. Check tire pressure regularly to maintain the 345kg load capacity per wheel.
