BMR Suspension Rear Cradle Lockout Kit

2006–2023 Chrysler 300, Dodge Challenger, Dodge Charger, Dodge Magnum

Part #: SCB110

Overview

The BMR Suspension Rear Cradle Lockout Kit is a precision-engineered upgrade designed to enhance the rear-end stability and traction of your Chrysler 300, Dodge Challenger, Charger, or Magnum from model years 2006 through 2023. This kit targets a common weak point in the factory suspension system—the soft, air-pocketed original equipment (OE) cradle bushings that allow excessive movement and wheel hop under acceleration and heavy loads.

By installing BMR’s lockout inserts, drivers experience a significant reduction in cradle deflection, resulting in improved chassis rigidity without sacrificing ride comfort or increasing noise, vibration, and harshness (NVH). This upgrade is ideal for enthusiasts seeking better power transfer, more predictable handling, and reduced wheel hop, especially in high-horsepower street or drag racing applications.

Key Features

The BMR Rear Cradle Lockout Kit combines advanced materials and design to deliver superior performance and durability. Key features include:

• CNC-machined from premium 6061-T6 billet aluminum for strength and precision fit
• Black anodized finish for corrosion resistance and a sleek, durable appearance
• Fills voids in factory cradle bushings to reduce deflection and movement
• Minimizes wheel hop, enhancing traction during aggressive acceleration
• Improves overall chassis stability and handling response
• Stronger and longer-lasting than OE rubber or polyurethane bushings
• Designed to maintain ride comfort without harshness or increased NVH
• Compatible with all models of 2006–2023 Chrysler 300, Dodge Challenger, Charger, and Magnum

Construction & Design

BMR Suspension’s Rear Cradle Lockout Kit is crafted from high-grade 6061-T6 billet aluminum, a material known for its excellent strength-to-weight ratio and resistance to fatigue. The inserts are CNC-machined to exacting tolerances, ensuring a perfect fit within the factory cradle bushings. This precision engineering eliminates the soft, compressible air pockets found in OE bushings, significantly reducing unwanted movement and deflection.

The black anodized coating not only provides a corrosion-resistant barrier but also delivers a clean, professional look that complements the undercarriage of your vehicle. The design balances rigidity with the need to avoid harsh ride characteristics, making it suitable for daily driving as well as performance applications.

Installation & Fitment

Installation of the BMR Rear Cradle Lockout Kit typically takes approximately 3 to 4 hours and requires basic mechanical skills and tools. The kit is designed to fit directly into the existing cradle bushings without the need for permanent modifications or bushing replacements, making it a straightforward upgrade for experienced enthusiasts or professional installers.

This kit fits all models of the Chrysler 300, Dodge Challenger, Dodge Charger, and Dodge Magnum produced from 2006 through 2023, ensuring broad compatibility across multiple platforms.
