30 lb force; 17-inch extended, 9.66-inch compressed; plastic socket ends.
Identify JR Products GSNI-5200 17-Inch Lift Supports
An RV baggage door, folding camper platform or truck-cap lid may still have its original 17-inch gas strut but no readable part label. JR Products' GSNI-5200 family has the same extended and compressed dimensions across five different forces. The correct replacement depends on both the measured strut and its original force rating.
Identify the correct force rating
All listed GSNI-5200 models share 17-inch extended length, 9.66-inch compressed length, 7.34-inch stroke, a 6 mm rod and 15 mm tube. The difference between these exact part numbers is their listed push force.

9.66 inFully compressed length

| Manufacturer MPN | Push force | Extended | Compressed | Stroke | End fitting |
|---|---|---|---|---|---|
| GSNI-5200-30 | 30 lb | 17 in | 9.66 in | 7.34 in | Plastic ball sockets |
| GSNI-5200-40 | 40 lb | 17 in | 9.66 in | 7.34 in | Plastic ball sockets |
| GSNI-5200-50 | 50 lb | 17 in | 9.66 in | 7.34 in | Plastic ball sockets |
| GSNI-5200-60 | 60 lb | 17 in | 9.66 in | 7.34 in | Plastic ball sockets |
| GSNI-5200-75 | 75 lb | 17 in | 9.66 in | 7.34 in | Plastic ball sockets |
Force is not the weight of the door. A 30 lb gas spring does not mean it holds exactly a 30 lb lid. Hinge position, installed angles and the number of springs affect the required force. Use the label from the original spring or an approved fit specification before changing ratings.
How to identify an unlabeled spring
- Secure the door first. Have another person hold it while the old support is removed. Never rely on a failing gas spring to hold the door.
- Measure fully extended length. Measure from the centre of one mounting end to the centre of the other; this family should measure 17 inches.
- Compare the closed length and travel. JR Products lists 9.66 inches compressed and 7.34 inches stroke for this exact family.
- Read the old force rating. Look for a pound rating or a force marked in newtons. Springs with the same length can exert different forces.
- Check socket and stud dimensions. These use plastic socket ends; confirm the existing ball studs, clips and mounting angles are compatible.
Installation and safety checks
- Position the replacement like the original, with the rod facing downward when the door is closed.
- Replace supports as a pair where the installation uses matching paired springs.
- Do not scratch or lubricate the polished rod, and never puncture or heat a pressurized spring.
- Check that each socket retaining clip locks after attachment. Test the door through its complete travel while supported.

Compare our 20-inch GSNI-5300 spring identification chart if the original spring belongs to a different length series. For a compartment door that will not latch, the issue may be in the door trigger mechanism, not the lift support. JR Products BS1005 10 mm ball stud is separately listed in our store; compare the original stud dimensions and installation before replacing a mounting point.
