Description
Upgrade the rear suspension and chassis connection of your high-performance Jeep Grand Cherokee Trackhawk and Dodge Durango SRT Hellcat with the SuperPro SPF5393K Rear Subframe Bushing Kit. These performance-engineered bushings replace the factory chassis-to-subframe mounting bushings to reduce unwanted subframe movement and improve suspension control, traction, and handling.
The suspension subframe provides a critical connection between the suspension system, vehicle body, and passenger compartment. Factory manufacturers often use soft, heavily voided rubber bushings in this area to prioritize comfort and isolation. As these OE rubber bushings age and deteriorate, they can allow excessive movement at the suspension mounting points, which can negatively affect traction, handling, and overall vehicle control.
On high-powered vehicles, soft or worn subframe bushings can also contribute to wheel hop during acceleration and increased suspension movement during changing loads or gear changes. These unwanted movements can reduce performance and compromise suspension control.
SuperPro subframe bushings are designed to enhance suspension performance while maintaining OEM-style levels of isolation and comfort. The synthetic elastomer materials used in SuperPro bushings are engineered to resist degradation caused by environmental exposure and varying suspension loads over the life of the vehicle.
The SPF5393K kit is designed for the rear chassis-to-subframe mounting position and provides a durable upgrade for performance-oriented applications where improved subframe control, traction, and handling are desired.
