Sea-Dog Gas Filled Lift Spring - 17" - 60#

The Sea-Dog Gas Filled Lift Spring – 17" – 60# is a precision hydraulic assist component engineered for controlled opening and closing of deck hatches, engine compartment lids, and other hinged access panels in marine and RV applications. Built to withstand salt-air corrosion and constant cycling, this gas spring delivers reliable support across freshwater and saltwater environments where traditional mechanical springs fall short. Whether you're upgrading a vintage RV, servicing a commercial marine vessel, or retrofitting automotive storage solutions, this Sea-Dog unit provides the damping consistency and load capacity needed for hands-free operation.

Manufactured to OEM marine standards, the Sea-Dog Gas Filled Lift Spring uses nitrogen gas pressurization to maintain a consistent 60-pound lifting force throughout its 17-inch stroke. The gas-filled rod design eliminates the sag and fatigue common to mechanical springs, ensuring smooth, predictable operation even after thousands of cycles. The compact 1-inch mounting footprint and lightweight 0.4-pound construction make installation straightforward on existing hardware, and the sealed cylinder design resists moisture intrusion and corrosion that typically compromises open-spring mechanisms. Every unit backs a full 2-year manufacturer warranty, reflecting Sea-Dog's confidence in durability across marine-grade service conditions.

Mechanics and restoration enthusiasts favor Sea-Dog gas springs for drop-down toolbox lids, compartment access doors, and engine bay hatches that require both safe support and hands-free closure. The 60# rating suits mid-weight panels and lids up to roughly 30–40 pounds when properly mounted with both rod and barrel anchors; verify your actual load and stroke length against the 17-inch specification before installation. Replacement is straightforward for most hinged applications—remove the old spring, align the new cylinder between anchor points, and secure using existing or new bolts. This versatile component is essential inventory for RV technicians, marine service centers, and DIY builders tackling custom storage and access modifications.
