StrongArm 4643 is engineered as a direct replacement for the trunk lid support used on this Mustang application. The pressurized cylinder helps maintain lift assist for the rear compartment lid, while the specific-fit design supports proper alignment with the factory mounting points. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

Common Problems This Part Can Help Solve

• Trunk lid that drops instead of staying open
• Weak or inconsistent lift assist when opening the rear compartment
• Slow, uneven, or noisy trunk lid movement
• Worn support that no longer holds the lid at full extension
• Reduced convenience when accessing the trunk on a Ford Mustang

Installation Notes

Verify vehicle fitment by year, model, and spoiler configuration before installation. Inspect the mounting points and ball socket ends for wear or damage before replacing the support. For proper operation and balanced support, replace lift supports in pairs when servicing the trunk lid.
