BMR Suspension Rear Cradle Bushing Kit (Polyurethane)

2005–2024 Chrysler 300, Dodge Challenger, Dodge Charger, Dodge Magnum

Part #: SCB111

Overview

The BMR Suspension Rear Cradle Bushing Kit (Polyurethane) is engineered to significantly reduce rear cradle movement in Chrysler 300, Dodge Challenger, Dodge Charger, and Dodge Magnum models from 2005 through 2024. Designed for enthusiasts seeking improved chassis stability and handling precision, this kit replaces the factory soft rubber bushings that allow excessive differential movement. Whether you’re driving aggressively on the street, competing in drag racing, or enhancing overall vehicle handling, BMR’s polyurethane cradle bushings deliver a firmer, more controlled rear suspension response.

By minimizing bushing deflection, this kit enhances rear suspension rigidity, reduces wheel hop, and improves traction during acceleration and cornering. It’s an essential upgrade for drivers who demand better performance and stability from their muscle cars without sacrificing daily drivability.

Key Features

Built to provide superior durability and performance, the BMR Rear Cradle Bushing Kit includes:

• 95-durometer polyurethane bushings for increased stiffness and longevity compared to OEM rubber
• Oversized 6061-T6 billet aluminum inner bushing sleeves for precise fitment and enhanced strength
• Zinc-coated hardware to resist corrosion and maintain reliable clamping force
• Significant reduction in bushing deflection and rear cradle movement for improved chassis control
• Greatly reduces wheel hop under hard acceleration for better traction and driveline stability
• Improves overall handling stability by increasing rear suspension rigidity
• Attractive red finish for long-lasting good looks and easy identification
• Designed and manufactured proudly in the USA to ensure quality and performance

Construction & Design

The kit features high-quality 95-durometer polyurethane bushings that resist the common issues of OEM rubber bushings, such as air pockets and premature wear. This material choice provides a firmer, more consistent connection between the rear cradle and chassis, reducing unwanted movement and improving feedback. The oversized inner sleeves are machined from 6061-T6 billet aluminum, offering superior strength and durability while maintaining precise alignment of suspension components.

All hardware is zinc-coated to prevent rust and corrosion, ensuring the kit maintains its performance and appearance over time. The red polyurethane bushings not only enhance durability but also add a visually appealing upgrade under the vehicle.

Performance & Sound

By reducing rear cradle movement and bushing deflection, this kit enhances traction and stability during aggressive driving maneuvers. The improved rigidity helps to eliminate wheel hop, a common issue in high-powered muscle cars, resulting in smoother launches and better control. While primarily focused on handling and chassis performance, the firmer bushings may also contribute to a more connected and responsive driving feel without introducing excessive noise or harshness.

Installation & Fitment

Installation of the BMR Rear Cradle Bushing Kit typically requires 3 to 4 hours and is designed to be a direct replacement for the factory bushings on compatible vehicles. No major modifications are necessary, but professional installation is recommended to ensure proper fitment and torque specifications. This kit fits a wide range of Chrysler 300, Dodge Challenger, Dodge Charger, and Dodge Magnum models from 2005 through 2024, covering multiple generations and trims.
