Overview
This black nitride shaft gas spring strut rod is a replacement-style lift support for compatible hatches, covers, RVs, campers, truck caps, and similar applications. It is listed under SPD GSNI-5100-30 and LGP6-120-30 references and measures 12" long with a 3-1/2" stroke and 30 lb force rating. The strut uses standard 10mm ends and is intended for applications where the original gas spring matches these specifications.
R&P Service Insight
Gas springs are measurement-sensitive parts. The best replacement is the one that matches the original strut’s extended length, stroke, force rating, and end connection style.
- Match the number: Compare your existing gas spring marking to SPD GSNI-5100-30, LGP6-120-30, or a verified equivalent.
- Match the size: Confirm the 12" extended length and 3-1/2" stroke before ordering.
- Match the force: Use 30 lb force only where that rating matches the original application.
- Match the ends: Confirm your mounting balls and brackets work with standard 10mm gas spring ends.
R&P Knowledge Hub
Compatibility: Compatible with applications requiring a 12" extended length, 3-1/2" stroke, 30 lb gas spring with standard 10mm ends.
Vehicle / System Fit: Commonly used for hatches, covers, RVs, campers, truck caps, lids, and similar lift-support systems.
Installation Notes: Replace only when the old gas spring is safely supported and the door, hatch, or cover cannot fall during removal. Verify end connection style before installation.

Brand & Fitment Note
Selling Brand: R&P Carriages replacement gas spring strut rod listing using LGP6-120-30 and SPD GSNI-5100-30 application references.
Application Reference: SPD and other brand names are used as part-number and compatibility references only.
What This Means: This listing is for one replacement-style black nitride shaft gas spring strut rod, not a guaranteed OEM-branded item unless specifically stated on the product packaging or order paperwork.
Before Ordering: Verify the extended length, stroke, force rating, end size, mounting hardware, and existing part number before installation.
R&P Repair Insight
A weak or failed gas spring can cause a hatch, cover, or camper door to drop, sag, or no longer stay open. Replacing with the wrong length or force rating can create poor fit, limited travel, or excessive lift pressure.
- Check length: Measure your old gas spring fully extended from mounting point to mounting point.
- Check pressure: Confirm the printed force rating on the old strut. This listing is for 30 lb force.
- Check mounting: Confirm your application uses standard 10mm ends before ordering.
- Replace in pairs when needed: If your hatch or cover uses two gas springs, replacing both sides can help maintain even lift support.
