Sierra Gas Springs

When it comes to marine-grade gas springs engineered specifically for the harsh demands of boating applications, Sierra has established itself as a trusted name with its Nautalift product line. These nitrogen gas-filled lift supports are designed as marine grade, exact OE replacements, making them ideal solutions for boat hatches, battery box lids, storage compartments, and cabin doors that require smooth, controlled opening and closing assistance.

Engineering Built for the Marine Environment

Sierra's approach to gas springs reflects the company's deep understanding of marine conditions. The Nautalift line features glass-reinforced polymer rod ends and an electrostatic black paint finish on steel tubes, providing essential corrosion resistance for components constantly exposed to moisture and temperature fluctuations. The engineering goes deeper than surface protection: these units incorporate a Tri-Lube seal, bronze bushings, and hard chrome-steel rods with micro finish that holds oil to lubricate seals. This multi-layer approach to durability ensures consistent performance even in demanding conditions.

Comprehensive Range for Different Applications

Sierra offers gas lift supports ranging from 5.5" to 7.5" and 7" to 10" extended lengths, with force ratings from 20lbs to 80lbs, providing boat owners with precise options for various hatch sizes and weights. Whether you're replacing worn supports on a compact tackle box lid or need heavy-duty assistance for large engine compartment hatches, the Nautalift lineup covers a wide spectrum of marine applications. Each unit is engineered as a direct OEM replacement, simplifying the installation process and ensuring proper fit.

Premium Stainless Options for Saltwater Environments

For boaters operating in particularly corrosive saltwater conditions, Sierra manufactures a premium stainless steel variant. These models feature 316L stainless steel rods and cylinders designed for demanding saltwater applications, offering maximum corrosion resistance for vessels that spend extended periods in marine environments. This material choice represents Sierra's commitment to providing solutions that match the specific challenges faced by saltwater anglers and cruisers.
