This heavy-duty mechanical leaf spring suspension assembly is specially engineered for heavy-haul semi-trailers, dump trailers and flatbed cargo carriers. The whole set includes leaf springs, hanger brackets, equalizer, U-bolts, torque rods and connecting accessories for a complete direct-fit installation. The trailer panhandle suspension adopts a streamlined panhandle-style structure layout, distributing axle load evenly during long-distance transportation. It can absorb road vibration effectively, protecting cargo safety while extending the service life of trailer frames and axles. Finished with anti-rust paint after precision casting and forging, the assembly adapts to rough road conditions for logistics, mining and construction transport scenarios.
