Meet the Trojan Trailer Coupling V2 2500kg Duofit 50mm & 1-7/8inch—the dual-fit hitch trusted by New Zealand trailer builders and widely fitted as original equipment. Built for reliability, this 2500 kg capacity coupling simplifies your towing setup by embracing both common tow ball sizes without fuss or extra parts. It’s the single, robust solution that keeps trailers moving, indoors or on the job site.

Two sizes, one secure connection

The Duofit mechanism senses tow ball size and self-adjusts to fit 50mm and 1-7/8" balls. No swapping handles or fittings—hitch, connect, and tow. This design minimizes downtime and reduces the risk of using the wrong ball size on a trailer, ensuring a consistent, dependable connection every time.

OE-grade reliability with retrofit ease

One footprint, no loose parts to misplace. The coupling automatically aligns with the correct ball size no matter which trailer you tow, and the sturdy housing with its spring-loaded mechanism is built to withstand daily hitching and unhitching.
