Upgrade your trailer suspension with the PS13D Parabolic Trailer Spring, a premium single-leaf eye-to-slipper spring designed for smooth towing, improved load distribution, and long-lasting durability. With a 600kg load rating per pair (300kg per spring), the PS13D is ideal for boat trailers, jet ski trailers, box trailers, camper trailers, and other light-duty trailers. Manufactured from high-quality heat-treated spring steel and finished with a Dacromet corrosion-resistant coating, the PS13D is built to withstand harsh Australian conditions and marine environments. The lightweight parabolic design reduces unsprung weight while delivering superior flexibility and ride comfort compared with conventional multi-leaf trailer springs.
