The 081649 gas spring from Ressorts SPEC is a corrosion-protected, value-driven strut engineered for marine service. Its nitrided black carbon-steel (GSNI SPEC) rod provides enhanced surface hardness and corrosion resistance, while the plastic ball-bushing end fittings ensure secure, lightweight connections ideal for confined lockers and deck hardware.
Delivering 150 Newtons of force over a 100 mm stroke, the unit measures 276 mm overall with end caps (body length 240 mm). Sized for common cockpit lids, lazarettes, and companionway panels, it offers smooth, damped support under way.
Corrosion performance is verified to the ASTM B117 salt-spray protocol. Note: SPD™ stainless-steel variants are validated to 500 hours of continuous salt spray; this nitrided carbon-steel version is designed as a cost-effective alternative for onboard use with proper rinsing and care.
Specifications
- Material: Nitrided black carbon-steel shaft (GSNI SPEC) with plastic ball-bushing end fittings.
- Force: 150 N – suitable for medium-duty hatch and locker applications.
- Stroke: 100 mm for controlled extension and closure.
- Total length with end fittings: 276 mm.
- Total length without end fittings (cylinder + rod): 240 mm.
- End fittings: Plastic ball bushings for snap-on installation to standard ball studs.
Installation / Maintenance
Installation
Snap the plastic ball bushings onto clean, correctly sized ball studs. Mount rod-down where possible to keep internal lubrication at the primary seal. Verify clearances at full extension and compression to avoid side loading.
Maintenance
After saltwater exposure, rinse with fresh water and wipe dry. Periodically mist the end joints with marine-grade silicone or lanolin. Inspect ball studs and brackets for play or corrosion; replace if worn.

Our review
✔ Pros
- Nitrided carbon-steel rod for hardened, corrosion-protected service.
- Marine-ready dimensions: 150N / 100 mm stroke / 276 mm OAL.
- Quick snap-on fit with plastic ball bushings.
- High value for refits and fleet maintenance.
✘ Cons
- Less corrosion resistance than full 316L stainless-steel models.
- Plastic ends are not recommended for high-impact, heavy lids.
Conclusion
The 081649 is a smart, budget-conscious choice for Bénéteau and Jeanneau installations where medium support is required and weight savings matter. If your use involves persistent green-water exposure or heavy lids, consider upgrading to a 316L stainless model for maximum longevity; otherwise this nitrided version delivers reliable, marine-ready performance with routine rinsing.
Good to Know
- Corrosion resistance evaluated to ASTM B117. SPD™ stainless variants are validated to 500 h continuous salt spray.
- Confirm extended length, stroke, and force against the original part before replacement.
