Spring Bag 5.0in OD Spring 18in x 20in Tall

The Spring Bag 5.0in OD Spring 18in x 20in Tall from Landrum Springs is a marine-grade suspension and impact control component engineered for trailers, boat lifts, and recreational watercraft support systems. This spring bag replaces worn or damaged factory components, restoring the original damping characteristics that keep your boat, trailer, and cargo secure during transport and docking operations.

Built with a 5.0-inch outer diameter and a height of 12.7 inches, the Spring Bag 5.0in OD Spring provides consistent load distribution and vibration absorption across heavy-duty marine applications. The robust construction handles salt-spray environments, fresh water exposure, and UV degradation without sacrificing elasticity or performance. Landrum Springs manufactures these components using reinforced elastomer materials rated for sustained weight cycles and temperature fluctuations typical of coastal and inland boating conditions.

Boat owners, trailer operators, and marine maintenance professionals rely on this component to maintain ride stability and prevent metal-to-metal contact that accelerates wear on frame components. The precision fit (MPN SB20) ensures direct bolt-in compatibility with OEM suspension brackets, eliminating the need for custom fabrication or modification. Whether you're launching a boat or transporting a trailer, this spring bag is essential for ensuring a smooth and stable ride.
