Marine & RV Hardware / Lift Support Systems
Nitride 17" Gas Strut Lift Support 20lb Force
High-performance nitrogen gas spring designed for marine boat hatches, RV storage compartments, and automotive lids requiring 20 lbs of lift force.
Part Number: LGP6-170-20 17.00" Extended Length 20 lb Force Rating
Overview
This LGP6-170-20 Gas Strut is a premium aftermarket replacement solution designed for marine, recreational vehicle, and utility applications. Featuring a Black Nitride rod finish, it provides superior corrosion resistance and smoother travel than standard chrome components. This unit is specifically calibrated for lids and hatches where a 17-inch extension and 20-pound compression resistance are required for safe, hands-free operation.
R&P Service Insight
In our experience with marine and trailer hardware, these gas springs are the "gold standard" for light-to-medium lids.
- Longevity Tip: Always mount with the rod pointing down to ensure internal seals stay lubricated with oil.
- Ease of Swap: Uses standard 10mm ball sockets for a quick, "snap-on" installation process.
- Force Awareness: 20 lbs is designed for light hatches; do not use for heavy engine covers.
R&P Knowledge Hub
Compatibility: Direct interchange for SPD-GSNI-5200-20 and similar 17" supports from Ameritool or Red Hound Auto.
Vehicle / System Fit: Commonly found on Malibu, Monterey, and Sea Ray boat hatches, as well as RV storage bay doors.
Installation Notes: Verify your ball stud size is 10mm. Use a flat-head screwdriver to slightly lift the safety clip during removal of old units.
Performance Insight: The Nitride finish is "case-hardened," meaning it won't flake or peel in saltwater environments like cheap chrome alternatives.
Brand & Fitment Note
Selling Brand: R&P Carriages / Verified Aftermarket Replacement
Application Reference: Any OEM or platform names (such as Malibu or Monterey) in this listing describe compatibility and application style only.
What This Means: This listing is for a high-quality aftermarket component, not a guaranteed OEM-branded item unless specifically stated.
Before Ordering: Verify the force (20 lbs) and extended length (17") match your current strut to ensure proper lid closure and lift.
R&P Repair Insight
Gas struts lose pressure over time due to seal wear. If your hatch no longer stays open in cold weather, the internal Nitrogen gas has likely escaped.
- Check 1: Measure from the center of the ball socket to the center of the other socket at full extension.
- Check 2: Look for the "P1" or "Force" rating on your old strut; it should be near 20 lbs or 90N.
- Check 3: Inspect ball studs for rust; if the stud is pitted, the new socket may not seat securely.
