Spring Bag 5.0in OD Spring 8in x 13in Tall

The Spring Bag 5.0in OD Spring 8in x 13in Tall from Landrum Springs is purpose-built for marine and boating applications where vibration isolation and load support are essential. Whether you're securing engines, generators, or equipment aboard, this spring isolator absorbs shock and reduces noise transmission to the hull and superstructure. For anglers and boaters who demand reliability during long days on the water, this component eliminates the fatigue caused by continuous engine vibration—allowing you to focus on fishing or navigation rather than mechanical noise.

Engineered with a 5.0-inch outer diameter spring and 8-inch x 13-inch tall profile, this spring bag delivers consistent dampening across a wide range of mounting scenarios common to cabin cruisers, center consoles, and commercial vessels. The compact 0.14-pound weight ensures minimal added mass while maintaining structural integrity under load. Its precision dimensions—5.05 x 1.5 x 13.1 inches—fit standard marine equipment mounts without modification, and the durable construction withstands saltwater exposure and constant engine cycling. The spring mechanism distributes forces evenly, reducing stress on fasteners and surrounding structure.

Boaters upgrading aging isolation systems or installing new equipment will benefit most from this Landrum Springs isolator. It pairs seamlessly with standard engine mounts, generator beds, and compressor installations found across recreational and commercial marine platforms. Installation is straightforward—stack or bolt the spring bag between the vibration source and the mounting surface—making it an economical solution for reducing fatigue cracks, loosened bolts, and cabin noise. This is the component serious boaters choose when durability and quiet operation matter on the water.
