Parts Desk Insights
Best Use Case: A practical choice when you need to restore hatch lid lift performance using a gas spring with the same 20" extended / 12" compressed geometry and a 120 lb force rating.
Common Issues: When replacing a gas spring, double-check that your hatch geometry matches the extended/compressed lengths and verify the mounting hardware on both ends; incorrect mounting geometry or mismatched ends can cause improper lift height or binding.
