Parabolic Trailer Spring – 1400kg Capacity Per Pair

Upgrade your trailer suspension with the PS18D Parabolic Trailer Spring, engineered to deliver superior ride quality, excellent load distribution, and long-lasting durability. Designed for boat trailers, caravan trailers, box trailers, and general-purpose trailers, this heavy-duty 18mm parabolic leaf spring provides a 1400kg load rating per pair (700kg per spring), making it ideal for medium to heavy-duty trailer applications. Unlike conventional multi-leaf springs, the PS18D single-leaf parabolic spring offers improved flexibility and reduced unsprung weight, resulting in smoother towing, better shock absorption, and less stress on your trailer chassis and cargo. The durable Dacromet-coated finish provides outstanding corrosion resistance, making it an excellent choice for marine environments and Australian road conditions.
