Installation Notes and Tips

Verify the vehicle is a 2005-2009 or 2010 Ford Mustang with front lower fitment before installation. This part uses a press-in mounting type and a threaded joint design, so proper suspension service tools are recommended for removal and installation. Confirm the stud type, wrench size, and mounting dimensions against the original part before assembly. Dorman 540-012 also cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.
