Sea-Dog Gas Filled Lift Spring - 15" - 30#

The Sea-Dog Gas Filled Lift Spring – 15" – 30# is a marine-grade gas spring engineered for reliable operation in demanding RV, boat, truck cap, and utility box applications. Built to original equipment manufacturer standards, this gas-charged strut delivers smooth, controlled lifting force with a load rating of 30 pounds, making it ideal for hatches, compartment doors, and equipment covers that require consistent support without manual effort or mechanical friction.

Featuring Sea-Dog's proprietary multi-lobe seal design, this 15-inch gas spring resists corrosion and wear in salt-air and high-moisture environments where standard lift springs fail prematurely. The sealed gas cartridge maintains constant pressure across thousands of cycles, eliminating the sagging or jerky operation common in mechanical springs. At 0.23 lbs and compact dimensions, it installs easily alongside existing hardware and requires no ongoing maintenance or adjustment. Every unit carries Sea-Dog's 2-year warranty, reflecting confidence in the manufacturing quality.

Marine and RV owners, truck customizers, and utility enthusiasts rely on gas springs to eliminate binding doors, reduce hand-operated strain, and extend the lifespan of hinges and latches. The 30-pound rating suits small-to-medium compartments and deck hatches; for heavier loads, higher-rated springs are available. Installation pairs with standard Sea-Dog fittings and mounting hardware for a professional, OE-quality result.

When reliability matters in salt spray, extreme temperature swings, or high-cycle-count applications, the multi-lobe seal and proven track record of Sea-Dog gas springs outperform lower-cost alternatives. This is the spring spec found in production marine cabins and premium RV systems.
