1250kg Drum Braked Hub Kit – 9" Hydraulic Drum, 5x4-1/2x1/2

The Trojan 1250kg Drum Braked Hub Kit is a hydraulically actuated braking solution engineered for trailers that demand dependable stopping power with straightforward maintenance. Built around a 9" hydraulic drum and a 5x4-1/2 bolt pattern, this kit is ideal for retrofit projects or new trailer builds on 1500kg beam axles, delivering consistent braking performance under heavy load.

• Capacities per pair: 1250 kg per pair, designed to provide reliable braking support for heavier trailer configurations without overloading the axle system.
• Drum size and performance: 9" hydraulic drum with a precise inside diameter for predictable bite and fade resistance during long highway runs.
• Shoe width: 1¾" shoe width to balance braking force and ensure smooth engagement across varying load conditions.
• Bolt pattern and studs: 5x4-1/2 bolt pattern with 1/2" studs for secure mounting and broad compatibility with common beam axles.
• Actuation type: Hydraulic actuation provides progressive, consistent braking power and reduces wear points associated with mechanical systems.
• Axle compatibility: Designed to fit 1500kg beam axles, making it suitable for mid- to heavy-duty trailer applications.
• Installation considerations: Stub axle is not included; the kit is ready to pair with your existing stub axle assembly, streamlining installation on compatible builds.
• Maintenance profile: Fewer rotating mechanical components and hydraulic actuation translate to longer intervals between service checks.

The 1250kg Drum Braked Hub Kit delivers solid, predictable braking for trailers that require reliable control under demanding conditions. It’s well suited for boat trailers, livestock trailers, and robust utility trailers that routinely carry heavy loads. The hydraulic drum design offers a smooth braking response, reduced risk of wheel lockups on descents, and better heat tolerance on long pulls. For retrofits, it lets you upgrade aging drum brakes to a modern hydraulic solution with straightforward installation on 1500kg beam axles. When building a new trailer, the kit’s proven 9" drum and 5x4-1/2 pattern provide a reliable foundation for braking performance you can trust ride after ride.
