Sea-Dog Gas Filled Lift Spring - 20" - 80#

The Sea-Dog Gas Filled Lift Spring – 20" – 80# is a precision-engineered support component designed for marine, RV, truck cap, toolbox, and utility hatch applications. Built to marine original equipment manufacturer standards, this gas spring delivers consistent lifting force and smooth operation across thousands of duty cycles. The 80-pound force rating provides reliable support for mid-weight lids and covers without requiring manual props or strain on hinges.

This 20-inch lift spring is engineered with Sea-Dog's multi-lobe seal design, which minimizes internal friction and extends service life in demanding environments. The sealed, pressurized nitrogen chamber maintains consistent force output even after extended exposure to salt air, temperature fluctuations, and repetitive cycling—conditions that break down standard springs quickly. At 0.5 lbs, the spring integrates easily into existing mounting systems without adding significant weight. All Sea-Dog gas springs carry a 2-year warranty, reflecting manufacturer confidence in durability and performance across marine and automotive applications.

This component is ideal for boat owners, RV enthusiasts, and truck accessory users who need reliable, maintenance-free lid support. The 80-pound rating suits applications requiring moderate lifting force—strong enough to hold a mid-sized hatch open without drift, yet not so heavy that operation becomes fatiguing. Whether securing a console cover on a center console, supporting an RV storage compartment, or propping a truck bed tonneau cover, this spring eliminates creep and provides consistent performance season after season without adjustment.
