EMCO Industries' High-Performance Mono-Leaf Spring for heavy-duty trailers features a 22,400-lb. gross-axle-weight-rated spring. According to the company, the new spring offers a 25% weight reduction compared to traditional 22.4K axle leaf springs, dropping from 53 lbs. to 40 lbs. It also exceeds Truck Trailer Manufacturers Association (TTMA) B-10 fatigue life requirements. Additionally, EMCO says that the new springs will be ideal for applications with lower suspension clearance, such as container chassis, flatbed trailers, and drive-on trailers. Both low-arch and high-arch configurations are available.
