Sea-Dog Gas Filled Lift Spring - 15" - 60#

The Sea-Dog Gas Filled Lift Spring – 15" – 60# is a pneumatic support mechanism engineered for hatches, compartments, lids, and tonneau covers on marine vessels, RVs, truck caps, and utility enclosures. Built to marine OE standards, this gas spring delivers consistent lifting force and smooth operation across thousands of open-close cycles, backed by Sea-Dog's 2-year warranty on all gas spring products.

At 15 inches in extended length with a 60-pound force rating, this spring provides controlled support for mid-weight applications where gravity alone would require operator effort. The multi-lobe seal design employed across Sea-Dog's gas spring line delivers superior service life and prevents seal degradation in harsh marine environments—critical in salt-air conditions where corrosion and moisture accelerate wear on standard mechanical hinges. This design also minimizes drift, ensuring the supported component holds position reliably even during vessel motion or extended idle periods.

Owners of center-console fishing boats, cabin cruisers, utility RVs, and truck-bed tool boxes depend on gas springs like this to reduce manual effort when accessing storage, engine compartments, or bunk areas—especially during rough seas or awkward angles where one-handed operation is necessary. The 60# rating strikes a balance between supporting substantial loads and remaining manageable for single-operator use. Installation is straightforward on existing hinge hardware or new custom mounts, making this a practical upgrade over worn mechanical springs or hydraulic struts that leak or fail prematurely in marine service.
