Whitecap 17" Gas Spring - 90lb - Black Nitrate

The Whitecap 17" Gas Spring - 90lb - Black Nitrate is a marine-grade support mechanism engineered for applications where controlled lifting and holding are critical. Whether you're managing a canvas bimini top, engine hatch, or helm seat on a center console, cabin cruiser, or sportfishing vessel, this gas spring provides reliable assistance without the wear and fatigue of manual props or struts. Built for saltwater and freshwater environments alike, it delivers consistent performance across seasons and operating conditions.

This 17-inch Whitecap unit generates 90 pounds of lifting force, striking a balance between smooth operation and adequate load capacity for mid-sized structural elements common on recreational and commercial vessels. The black nitrate finish resists corrosion from saltwater spray, UV degradation, and humidity—critical for long-term reliability in harsh marine environments. The internal gas charge maintains consistent force throughout the full stroke, preventing sudden drops or sluggish action that can compromise safety or comfort. The compact form factor integrates cleanly into tight spaces where traditional hinges or mechanical supports would be impractical.

Marine professionals and boat owners who demand durability without maintenance prefer Whitecap springs for their straightforward installation and decades-long track record. Installation requires pilot holes and standard fasteners—most jobs take under an hour with basic hand tools. Verify mounting surface material and load distribution before installation to ensure the 90-pound force aligns with your application's weight requirements. This spring suits covers, lids, doors, and hatches on vessels ranging from 17 to 35 feet, making it an essential upgrade for any boater seeking hands-free convenience and reliability on the water.
