How to Find the Right Trojan Part

Trojan parts use a systematic numbering system. When replacing parts, the easiest approach is:

1. Check the existing part number stamped on your current component
2. Measure the stud pattern (e.g., 5×4½" or 6×5½") for hubs and drums
3. Know your trailer's GTM (Gross Trailer Mass) rating for axles and brakes
4. Call us on 09 820 8023 if you're unsure — we can cross-reference
