Motoforti Marine Stainless Steel Lift Supports

The Motoforti lift supports are designed for marine hatch covers, car hoods, RV doors, and cabinet lids. They use stainless steel construction to resist rust and corrosion, making them suitable for rainy or snowy weather. Specifications include a 7.5 inch extended length, 5.25 inch compressed length, and a force rating of 20 lb (90 N). They are offered as a two-piece set with plastic end fittings, and are positioned for heavy lid support in wet environments. The product’s versatility covers marine hatch compartments and other heavy lids on boats and RVs.
Vepagoo 15 Inch Stainless Steel Gas Struts

Vepagoo gas struts are built from 316 stainless steel for seawater resistance, ideal for boats, ships, and outdoor storage. The set includes two struts (1 pair) and has an extended length of 14.96 inches with a compressed length of 9.06 inches, delivering 10 lb (44 N) of force. They’re suitable for boat hatches, RV beds, cabinets, and other lids up to 8–11 lb, with a rotatable ball connector for flexible mounting. No screws are included, so readiness for direct installation varies by existing hardware on the lid or hatch.
ARANA 20-Inch Marine Gas Struts (Pair)

ARANA’s 20-inch gas struts come in a pair and use 304 stainless steel for seawater resistance and high-temperature tolerance. They are designed for boat hatches, ship lockers, and outdoor storage. The extended length is 20 inches with a suitable installation for heavy lids like bilco doors or canopy rear windows. These struts are marketed for one-handed operation and straightforward mounting, helping to open and hold lids with reliable marine-grade performance in rough conditions.
SEACHOICE Gas Spring, 316 Stainless Steel

SEACHOICE offers a compact, lightweight gas spring in 316 stainless steel. It provides controlled lift for doors, cabinet doors, windows, hinged lids, and tabletops. The design emphasizes a smooth, steady extension that replaces traditional springs in marine or outdoor settings. Its corrosion resistance and reliable performance make it a practical choice for hatch doors and small lids on boats, campers, and trailers where consistent assist is needed without bulk.
ARANA 15-Inch Stainless Steel Gas Struts (Pair)

ARANA’s 15-inch gas struts pair features 304 stainless steel for corrosion resistance, suited for wet and harsh environments. Extended length of 15 inches and compressed length around 8.82 inches align with a variety of lids and compartments. This model is intended for boat lockers, RV campers, tonneau covers, and canopy tops, offering easy installation and dependable one-handed operation for marine and outdoor applications where frequent lid access is required.
Buying Guide: Key Purchase Considerations
- Material and corrosion resistance: Prioritize 304 or 316 stainless steel for marine use to resist seawater, humidity, and salt spray. 316 stainless steel typically offers higher corrosion resistance in harsh marine environments.
- Extended and compressed length: Match the extended length to the lid’s maximum opening and ensure the compressed length fits in the available space. Check load range to prevent over-stressing or insufficient support.
- Load rating: Choose a force that safely supports the lid without sagging or difficulty opening. Common boat and RV lids benefit from 10–60 lb ratings depending on lid weight.
- Mounting compatibility: Look for rotatable ball joints or easy mounting points, and confirm whether screws are included. Some models use universal brackets suitable for multiple lid types.
- Installation and maintenance: Opt for products with straightforward installation steps and minimal maintenance. In wet environments, regular inspection for rust or wear is advised.
- Application versatility: If you need to cover multiple lid types (hatch, locker, canopy), consider a set with different length options or a paired kit tailored to marine use.
- Replacement compatibility: When replacing OEM struts, compare interchange numbers, extended length, and piston diameter to ensure a proper fit.
In summary, the five selections provide robust options for marine applications, emphasizing stainless steel construction, appropriate load ratings, and compatibility with common hatch and lid configurations. When choosing, consider the exact lid weight, opening angle, and mounting constraints to maximize performance and longevity in marine environments.
