Sea-Dog Gas Filled Lift Spring - 17" - 30#

The Sea-Dog Gas Filled Lift Spring — 17" — 30# is a precision hydraulic support component engineered to marine OE standards for reliable hood, hatch, and compartment operation in harsh saltwater and demanding off-road environments. Built with Sea-Dog's proven multi-lobe seal design, this gas spring delivers consistent lifting force while resisting corrosion inherent to marine, RV, and truck bed applications where traditional mechanical springs fail prematurely.

At 30 pounds of lift force across a 17-inch stroke, this gas spring provides smooth, controlled motion without the jarring release of mechanical springs or the maintenance overhead of cable systems. The sealed gas chamber operates independently of temperature fluctuations, maintaining consistent force whether deployed in freezing northern climates or high-heat desert conditions. Weighing just 0.4 pounds, the compact profile fits tight engine bay spaces and storage compartments without adding structural stress or requiring reinforcement brackets. Sea-Dog backs every gas spring with a 2-year manufacturer warranty, reflecting confidence in the multi-lobe seal's durability against salt spray, UV exposure, and repetitive cycling.

Buyers restoring or upgrading marine hardtops, RV wet bays, truck tool boxes, and utility compartments rely on this Sea-Dog unit to replace worn factory springs without modification to existing mounting hardware. The 30# rating suits mid-weight covers and access panels; heavier applications require higher-force alternatives. Installation requires two units per lid for balanced support and safe operation — a critical detail often overlooked in single-unit purchases.

Gas springs for marine and RV use have become the industry standard over mechanical alternatives due to superior reliability in corrosive salt-air environments and smoother user experience. Sea-Dog's market positioning as a OEM supplier ensures engineering parity with equipment manufacturers rather than aftermarket approximations.
