The Galvanised Trailer Leaf Slipper Spring delivers heavy-duty suspension performance for boat trailers carrying larger and heavier vessels, with the 5-leaf configuration providing a substantial spring rate suited to high-load trailer axle applications. Each additional leaf contributes to the overall load capacity, ensuring the spring maintains controlled flex and effective road shock absorption during towing whilst distributing the vessel weight evenly across the axle. The galvanised finish provides the corrosion resistance necessary for trailer components regularly submerged or exposed to water during launching.Galvanised Trailer Leaf Slipper Spring 5 Leaf - Trailer Parts 5-Leaf Heavy-Duty Configuration - five-leaf stack delivering a high spring rate suited to heavy trailer and vessel combinations requiring substantial load-carrying capacity Controlled Suspension Travel - slipper end design enabling correct flex and controlled travel as the spring absorbs road shock during towing Galvanised Corrosion Protection - galvanised finish providing essential corrosion resistance for trailer springs regularly exposed to water and salt during launching operations
