• 38mm round stub axles included, featuring a built-in caliper mount for straightforward installation and alignment.
• Wide range of stud patterns to fit the most common wheels. Available in 5-stud (4 1/2" PCD = 67.183mm) and 6-stud (5 1/2" PCD = 82.118mm) with 1/2" studs.
• Trojan compatibility plus NZ practicality: designed to fit Trojan products, yet adaptable enough to suit many NZ-manufactured trailer axles for easy sourcing and replacement parts.

Rotor and hub options

The kit supports non-braked hubs with a rotor that either comes integrally built into the hub or is bolt-on, with choices in cast iron or stainless steel. Calipers are not included and are sold separately, so you can pair with your preferred caliper setup.

• Integral rotor — one-piece hub with rotor built in.
• Cast iron bolt-on rotor — bolt-on rotor options in multiple stud patterns and mounting configurations.
• Stainless bolt-on rotor — corrosion-resistant choices ideal for coastal or salt-prone environments, available in equivalent stud patterns.
