Its design avoids pin alignment issues, stays compatible with off-road chassis mods, and maintains full ADR compliance.
Installation Suggestions
-
Ensure your drawbar plate matches the 184 × 54 mm bolt pattern.
-
Bolt coupling loosely at first, then tighten evenly to spec.
-
Remove rear collar when towing—only reinstall during reversing to avoid unintended braking.
-
Inspect articulation regularly and grease pivot areas if used in sandy or gritty environments.
