SuperPro Rear Upper Forward Diff Pinion Mount Bush Set
2011–2021 Chrysler 300, 2015–2023 Dodge Challenger / Charger
Part #: SPF5191K
Overview
The SuperPro Rear Upper Forward Differential Pinion Mount Bush Set is a precision-engineered upgrade designed to enhance the rear differential stability of Chrysler 300, Dodge Challenger, and Dodge Charger models spanning 2011 to 2023. This kit addresses the common issue of premature wear found in factory rubber bushings, especially under the increased loads experienced by high-performance variants such as the SRT and Hellcat.
By replacing the original mounts with durable polyurethane bushings, this kit improves rear traction, reduces drivetrain noise and vibrations, and extends the service life of your vehicle’s differential components. It is an ideal solution for enthusiasts seeking improved handling and durability, as well as daily drivers who want a quieter, more refined ride without sacrificing comfort.
Key Features
SuperPro’s Rear Differential Pinion Mount Bush Set delivers a range of benefits that make it a superior choice over standard rubber mounts:
- Enhances vehicle handling and rear traction by stabilizing the differential mount
- Manufactured from proprietary engineering-grade polyurethane for exceptional durability
- Resistant to extreme temperatures, oils, water, and coolant exposure
- Reduces noise, vibration, and harshness (NVH) transmitted to the cabin
- Significantly extends bushing service life compared to factory rubber components
- Precision-engineered for the forward mounting points on the rear differential
- Backed by a lifetime warranty for long-term peace of mind
- Designed, engineered, and manufactured in Australia to exacting standards
Construction & Design
This bush set features SuperPro’s proprietary polyurethane compound, which strikes an optimal balance between stiffness and compliance. Unlike traditional rubber bushings that degrade quickly when exposed to heat, oils, and chemicals, these polyurethane mounts maintain their shape and performance over time. Their resistance to environmental contaminants ensures longevity even in demanding driving conditions.
The design focuses on controlling differential movement under load, providing a firmer yet refined connection between the differential and chassis. This reduces unwanted movement that can lead to drivetrain wear and compromised handling.
Performance & Sound
By stabilizing the rear differential, the SuperPro pinion mount bush set improves traction and handling responsiveness, particularly during acceleration and cornering maneuvers. The reduction in differential movement also minimizes unwanted noise and vibrations, resulting in a quieter and more comfortable cabin environment. This upgrade is especially beneficial for high-performance models where differential stress is significantly increased.
Installation & Fitment
The kit is a direct-fit replacement for the rear differential pinion mount bushings on 2011–2021 Chrysler 300, 2015–2023 Dodge Challenger, and 2015–2023 Dodge Charger models, including RT trims. Installation requires standard mechanical tools and moderate automotive knowledge. No modifications to the vehicle’s chassis or differential are necessary, making it a straightforward upgrade for professional installers and experienced enthusiasts alike.

What does the Available to Promise date mean?
ETA stands for Estimated Time of Arrival. The date shown is calculated using our Available-to-Promise (ATP) system, which tracks real-time supplier commitments to determine when a product is expected to be available for delivery. Specifically, the date is calculated by adding 9 business days from the date a supplier has committed to ship the product, representing a worst-case scenario for when we can expect to receive inventory.
Please note: The ETA is an estimate, not a guarantee. While we work closely with our suppliers to keep dates as accurate as possible, delays due to shipping carriers, weather, customs, or supplier-side issues may occasionally push the actual arrival beyond the date shown. Likewise, inventory may arrive sooner than the ETA in many cases. If you would like to be notified for when this item arrives, sign up for our back in stock notifications!
