Choosing between a 4-hole and a 6-hole OzHitch off-road coupling is an important decision to ensure the best towing performance for your trailer or caravan. Both configurations are designed for strength and durability, but the right choice depends on the weight of your load, the terrain you’ll be towing on, and the specific needs of your setup. Here’s a breakdown to help you decide.

4-Hole OzHitch Coupling
The 4-hole coupling is the most common choice for standard towing needs, providing a solid and reliable connection for light to mid-weight trailers and caravans. It’s a perfect solution for those who tow regularly on paved roads or light off-road conditions.
Key Features:
- Bolt Hole Dimensions: Typically measures 184mm x 54mm for 2.0T and 3.5T models. The 2.5T model has a 104mm x 76mm bolt hole pattern.
- Suitable For: Trailers with up to 2.5 tonnes (ATM), including unbraked trailers and those with electric or override brakes.
- Best Use Case: Ideal for standard towing and light off-road use, including caravans, camping trailers, and small utility trailers.
- Ease of Installation: The 4-bolt design makes for quick installation, and it fits most drawbars without the need for modification.
6-Hole OzHitch Coupling
The 6-hole coupling is designed for more heavy-duty towing and provides extra stability, especially for larger caravans or off-road trailers that encounter rugged terrain. The additional two bolts increase the overall strength and durability of the connection, making it ideal for extreme off-road conditions or heavier loads.
Key Features:
- Bolt Hole Dimensions: The 6-hole configuration shares the same outer dimensions as the 4-hole pattern, 184mm x 54mm, with additional centre holes spaced at 76mm for added support.
- Suitable For: Trailers with up to 3.5 tonnes (ATM), especially those used in extreme off-road conditions.
- Best Use Case: Perfect for heavy-duty towing on rough terrains where increased articulation and strength are required. Ideal for larger off-road caravans, trailers carrying heavy loads, or adventure trailers.
- Enhanced Stability: The additional two bolts ensure a more secure connection and reduce the chance of movement or wobble, even on rough roads.
Which Should You Choose?
Choose the 4-Hole Coupling If:
- You tow lighter trailers or caravans with 2.5 tonnes or less (ATM).
- Your towing involves mostly paved roads or light off-road conditions.
- You need a simple, quick installation and don’t require the extra stability of the 6-hole design.
Choose the 6-Hole Coupling If:
- You tow larger trailers or caravans with up to 3.5 tonnes (ATM).
- You frequently tow in rugged off-road environments that demand maximum stability and articulation.
- You require extra durability and strength to ensure secure towing, especially when carrying heavier loads.
Why Bolt Hole Configuration Matters
The bolt hole configuration plays a critical role in the stability and strength of your towing setup. The 4-hole configuration is sufficient for most day-to-day towing tasks, while the 6-hole version provides extra reinforcement, making it the go-to choice for heavy-duty and off-road adventures.
By choosing the correct configuration, you’ll ensure that your trailer or caravan remains secure and balanced throughout your journey, reducing the risk of coupling failure and enhancing overall safety.
