Detailed Description

The listed dimensions help match the support to the original application, which is important for proper lift height, closing effort, and tailgate control.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What It Helps Address

• Tailgate or hatch that will not stay open
• Weak lift support pressure
• Uneven or slow tailgate movement
• Excessive effort required to raise the rear hatch
• Loss of controlled closing action

Installation Notes and Tips

Verify the vehicle application by year, make, and model before ordering. Compare the original support’s compressed length, extended length, and stroke length to confirm proper replacement for the rear tailgate position. For best results, inspect the mounting points and surrounding hardware for wear before installing the new support.
