It is a fitment-based replacement for select Dodge Durango and Jeep Grand Cherokee models, with application notes that must be matched before ordering.

Key Features

• Provides a pivot point that helps the suspension rotate smoothly during steering and road movement.
• Locks the strut and body together for secure mounting.
• Includes noise-dampening characteristics to reduce road vibration transfer into the cabin.
• Uses materials selected for the application and a finish intended to support appearance and service life.
• Cross-references Monroe Shocks & Struts 908999 and KYB SM5684 for the same application.

Detailed Description

Westar ST-8999 is a rear suspension strut mount engineered for vehicles that rely on a precise upper mount to control suspension motion and isolate vibration. In compatible Dodge Durango and Jeep Grand Cherokee applications, the mount helps maintain suspension geometry while supporting the strut assembly at the body connection point. The design focuses on rotation control, secure locking, and noise isolation, which are all important for consistent ride behavior and reduced wear on related components. Westar ST-8999 is a practical replacement choice when the original mount shows wear, noise, or looseness.

This part cross-references Monroe Shocks & Struts 908999 and KYB SM5684 for the same application. Westar ST-8999 is also listed for 2011-2015 Dodge Durango rear, excluding Auto Leveling System, and 2011-2013 Jeep Grand Cherokee rear with Stud Plate Only notes, so fitment details should be verified carefully before installation.
