Parts Desk Insights
Best Use Case: A direct replacement gas spring when your existing hatch lift support is losing hold-up force or no longer reaches the correct position—match the lengths and 40 lb force rating so your hatch opens and closes smoothly.
Common Issues: Using the correct spring size matters: if the compressed/extended lengths don’t match your hatch geometry, the hatch may sit too high/low or feel inconsistent. Also confirm you have the correct mating end-fittings/bracket set (brackets are sold separately).
