JR Products GSNI-5300 20-Inch Gas Spring Force & Size Guide

The GSNI-5300 range provides 20-inch extended gas springs in six force ratings, from 10 to 60 lb. The dimensions are shared within this family, but lifting force varies by exact model. Compare the fully extended length, compressed length, stroke and original force before ordering a replacement.

Compare the available force ratings

All listed GSNI-5300 models share 20-inch extended length, 11.41-inch compressed length, 8.59-inch stroke, a 6 mm rod and 15 mm tube. The difference between these exact part numbers is their listed push force.

Do not choose by pounds alone. The force rating is the spring's push force, not the maximum door weight. An overly strong replacement can stress a compartment lid or hinge; one that is too weak may not hold it safely. Match the original force and mounting geometry.

How to measure a replacement gas spring

  1. Support the hatch or door. Follow JR Products' installation instructions and keep the panel securely held during replacement.
  2. Measure centre to centre. With the spring fully extended, measure the distance between the centres of its end connectors: 20 inches for this family.
  3. Confirm compressed length and stroke. The published compressed length is 11.41 inches, with 8.59 inches of travel. They are not interchangeable with another same-force model of a different length.
  4. Match the force marking. The suffix indicates pounds of force; if the original is marked in newtons, convert or obtain the manufacturer's specified replacement.
  5. Check the installed ends. Plastic sockets with retaining clips must fit the existing ball studs and remain secure through the full door movement.

Installation and safety checks

  • Keep the door safely supported and follow the original installation orientation, with the rod downward in its closed position.
  • For paired installations, replace both springs with correctly matched supports.
  • Inspect ball studs and clips before reassembly. Do not scratch, oil or grease the rod.
  • Make sure the mounted spring does not bottom out before the lid closes, and that the latch opens and closes freely.

If your existing support is a different length, review the 17-inch GSNI-5200 gas spring comparison. For an RV compartment that is difficult to close, see the separate trigger latch comparison before replacing unrelated hardware. 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.
