Hub and Stub Kits Cl Disc 5x4 1/4x7/16

Introducing the Hub and Stub Kits Disc 5x4 1/4x7/16—the robust, ready-to-brake solution designed for NZ trailers. These disc-braked hub kits are engineered to fit Trojan Duratorque and beam axles, and they’re compatible with most NZ manufactured trailer axles for flexible retrofits or new builds.

Why this kit stands out

• High-capacity performance: Each hub kit is rated for up to 1500 kg GVM per axle when used as a pair, delivering strong braking performance for mid-weight trailers.
• Complete hub assembly: The set includes two hubs with a pair of 38 mm round stub axles and a built-in caliper mounting point, providing a clean, ready-to-install solution. Calipers are sold separately, giving you control over your brake hardware choices.
• Disc options to suit your build: Choose between a full cast disc or a bolt-on disc, available in cast iron or stainless steel for corrosion resistance in demanding environments.
• Extensive stud patterns for common rims: A wide range of wheel stud patterns ensures compatibility with the most commonly stocked NZ rims and tyres, including 4x4¼, 4x4½, 5x4¼, 5x4½ and 5x120 configurations.
• Built for durability: The kits feature sturdy components designed to handle the rigors of daily trailer use, with options that reflect real-world conditions—from coastal salt to dusty worksites.

Key configurations and compatibility

The Disc Hub Kits offer both integral and bolt-on disc options to match your axle and wheel setup:

• in various stud patterns, including 4x4¼, 4x4½, 5x4¼, 5x4½, and 5x120, with corresponding PCD and width measurements for precise fitment.
• available for 5x4¼, 5x4½, and 5x120 patterns—ideal where a bolt-on mounting is preferred for serviceability and replacements.
• in 5x4½ and 5x120 patterns for enhanced corrosion resistance and longevity in challenging environments.

Compatibility is built in: these hubs are designed to fit Trojan Duratorque and beam axles, and should also accommodate most NZ manufactured trailer axles. If you’re updating a fleet or upgrading from drum brakes to discs, this kit provides a reliable path to improved stopping power and better heat dissipation under load.
