Fixed Front Hanger for Heavy-Duty Leaf Spring Suspension
The 45mm Dumbjack Hanger is the essential fixed mounting point for standard trailer leaf spring setups. Designed for durability and precision, this hanger provides the strength needed to anchor your suspension system to the trailer chassis, ensuring correct tracking and load distribution.
Constructed from heavy-duty plate steel, this hanger is built to endure the high-stress environment of Australian roads, making it a staple for utility, box, and tradesman trailers.
Key Features
Dumbjack Profile: Engineered as a fixed front hanger to provide a rigid pivot point for your leaf springs.
45mm Spring Compatibility: Perfectly sized for all standard 45mm wide leaf springs, ensuring a snug fit that prevents spring twist.
9/16″ Pivot Bush: Precision-bushed to accept standard 9/16″ shackle or pivot bolts, providing a secure and reliable connection.
Weld-Ready Steel: Raw steel finish allows for deep weld penetration directly to the trailer frame (RHS, SHS, or Channel).
Heavy-Duty Gauge: Thick-wall construction prevents “egging” of the bolt hole under heavy load cycles.
