BMR Suspension Polyurethane Differential Mount Bushing Kit

2005–2023 Dodge Charger, 2005–2008 Dodge Magnum

Part #: DMB111

Overview

The BMR Suspension Polyurethane Differential Mount Bushing Kit is a high-performance upgrade designed to replace the factory rubber bushings in Dodge Charger and Magnum models from 2005 through 2023. This kit significantly reduces differential movement and wheel hop, delivering enhanced rear-end stability and sharper handling characteristics. Ideal for enthusiasts who demand improved traction, smoother launches, and a more connected driving experience, the kit is engineered to perform on both street and track without compromising daily drivability.

Factory differential bushings are made from soft rubber that allows excessive movement under load, leading to inconsistent traction and a vague rear-end feel. BMR’s polyurethane bushings provide a firmer, more precise connection between the differential and chassis, resulting in improved vehicle control and responsiveness during aggressive acceleration and cornering.

Key Features

Engineered for durability and performance, the BMR Differential Mount Bushing Kit offers the following benefits:

• Fits 2005–2023 Dodge Charger and 2005–2008 Dodge Magnum models
• Constructed from 95-durometer red polyurethane for long-lasting wear
• CNC-machined to exact tolerances for a precise fit and straightforward installation
• Greatly reduces differential movement and deflection under acceleration and cornering
• Decreases wheel hop for improved traction and smoother launches
• Enhances rear-end stability and handling feel during spirited driving
• Minimizes changes in noise, vibration, and harshness (NVH) for comfortable daily driving
• Durable red finish resists wear and adds a performance-oriented look
• Proudly designed and manufactured in the USA

Construction & Design

The bushings are crafted from premium 95-durometer polyurethane, chosen for its ideal balance of stiffness and compliance. This hardness level ensures the bushings resist deformation under load while still absorbing some vibration to maintain ride comfort. Each bushing is CNC-machined to exact specifications, guaranteeing a perfect fit that aligns precisely with the differential mount points.

The vibrant red polyurethane finish not only provides durability against environmental factors but also adds a distinctive, performance-inspired appearance beneath the vehicle. BMR Suspension’s design focuses on reducing unwanted differential movement without introducing excessive harshness, making this kit suitable for both street and track applications. The robust construction ensures long service life even under demanding driving conditions.

Installation & Fitment

Installation of the BMR Differential Mount Bushing Kit typically requires 4 to 5 hours and is recommended to be performed by a professional or experienced enthusiast. This kit is a direct replacement for the factory bushings and fits all 2005–2023 Dodge Charger and 2005–2008 Dodge Magnum models without any modifications. Proper installation improves rear suspension geometry and reduces drivetrain lash, contributing to better vehicle control and overall performance.
