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

The Sea-Dog Gas Filled Lift Spring – 20" – 80# is a hydraulic support component designed for automotive hoods, engine covers, hatch lids, and equipment access panels where smooth, controlled lift assistance is essential. This lift spring is ideal for anyone working on vehicles that require reliable hold-open support, such as classic restorations or retrofitting marine and RV equipment.

Utilizing gas-filled (nitrogen-charged) technology, this unit stores energy in a sealed cylinder to deliver smooth, linear force output throughout its stroke length. The 80-pound force rating indicates the amount of lifting assist the spring provides, ensuring it can support substantial weight without bottoming out or requiring excessive manual push-down force to close. Built by Sea-Dog, this gas-filled unit is designed to perform consistently across temperature ranges and repeated cycles.

This lift spring is particularly beneficial for applications in truck hoods, automotive engine bays, and equipment enclosures. Gas-filled designs outperform traditional coil springs by maintaining consistent force across temperature extremes, resisting fatigue from repeated cycling, and eliminating sagging over time. With a compact weight of approximately 0.5 lbs, it is easy to install and handle.
