Parts Desk Insights
Best Use Case: Ideal for restoring hatch or access-port lift support when your existing gas spring has lost pressure or no longer holds reliably at the intended open/closed positions.
Common Issues: Before installing, compare your current spring’s extended length, compressed length, and force rating (the mounting brackets can change the fit). Also verify the mounting/socket features—this model references a 10mm composite socket and an 8mm rod, and brackets are sold separately.
