KYB SM5684 Shock Mount - Rear Upper

Rear Upper Strut Mount for Durango and Grand Cherokee

KYB SM5684 is a rear upper suspension shock absorber mount built for specific Dodge Durango and Jeep Grand Cherokee applications. It replaces worn vibration insulators and bearing components that can transmit noise, harshness, and steering-related movement into the vehicle.

As part of KYB Mount Components, this SM5684 strut mount is engineered as an OE-quality replacement for the rear upper position on select Durango and Grand Cherokee models.

Key Features

• OE-quality replacement strut mount for the rear upper suspension position
• Superior rubber helps reduce noise, vibration, and harshness from the road
• Mount bearings support smoother steering response and help retain front-end alignment
• Matched-grade studs and nuts for application-specific fitment
• Built to restore suspension performance after worn or hardened mounts

Detailed Description

KYB SM5684 is designed to replace the rear upper suspension shock absorber mount on 2011-2015 Jeep Grand Cherokee models without self-leveling rear suspension, 2011-2015 Dodge Durango models without load leveling suspension, and 2016-2019 Dodge Durango models without load leveling suspension or sport suspension, plus 2020-2025 Dodge Durango models with normal suspension and without load leveling suspension. This part number, SM5684, addresses the vibration isolation and bearing support functions that are critical to ride quality and suspension control.

KYB Mount Components focus on restoring the original suspension behavior of the vehicle. On applications like the Dodge Durango and Jeep Grand Cherokee, the rear upper mount helps cushion impacts from bumps while reducing the jarring effect that worn mounts can transfer into the cabin. The bearing plate design also supports steering and alignment stability where applicable in the suspension system.

What It Helps Fix

• Clunking or knocking from worn rear upper mount components
• Excess cabin vibration from hardened vibration insulators
• Harsh ride quality over bumps and rough pavement
• Steering feel affected by worn mount bearings
• Front-end alignment issues related to mount wear

Installation Notes and Tips

Verify suspension configuration before ordering. This part is for the rear upper position only and does not fit Durango models with load leveling suspension or sport suspension, or Grand Cherokee models with self-leveling rear suspension. Confirm the vehicle year, make, model, and suspension setup against the fitment list before installation.

For best results, inspect related strut and suspension wear items during service. Proper torque and alignment procedures should be followed after installation.

Quality Assurance

KYB is known for OE-style suspension replacement components, and the Mount Components line is built to match application-specific requirements for fit and function. SM5684 is engineered to deliver the vibration isolation, bearing support, and suspension performance expected from a quality replacement mount.
