Upgrade your trailer suspension with the PS15D Parabolic Trailer Spring, a premium single-leaf eye-to-slipper spring engineered for superior towing performance, improved load distribution, and exceptional durability. With a 1000kg load rating per pair (500kg per spring), the PS15D is ideal for boat trailers, jet ski trailers, caravan trailers, box trailers, and other medium-duty trailers. Manufactured from high-quality heat-treated spring steel and protected with a Dacromet corrosion-resistant coating, the PS15D is designed to withstand Australia's harsh road and marine environments. Its lightweight parabolic design reduces unsprung weight while providing a smoother ride, improved shock absorption, and reduced stress on your trailer chassis and load.
