Construction & Design:

Whiteline utilizes premium-grade polyurethane material that offers a perfect balance of stiffness and compliance. Unlike traditional rubber bushings that degrade and flex excessively over time, these polyurethane bushings maintain their shape and performance under high stress. The material’s resistance to heat, oil, and road contaminants ensures long-lasting durability even in demanding driving conditions.

The bushings are precision molded to exact OEM dimensions, ensuring a direct fit without the need for modifications. This careful engineering preserves the factory suspension geometry while significantly enhancing chassis rigidity. The design focuses on reducing unwanted movement in the rear crossmember, which is critical for maintaining traction and vehicle control during aggressive acceleration and cornering.

Installation & Fitment:

Installation of the Whiteline Rear Crossmember Bushings is straightforward and designed to be a direct replacement for the original equipment bushings. No special tools or fabrication are necessary, making it accessible for professional mechanics and experienced enthusiasts alike. The bushings fit all 2WD Chrysler 300C, Dodge Challenger, Charger, and Magnum V8 models from 2005 through 2010, including Hemi and SRT8 variants.

For best results, it is recommended to have the rear suspension alignment checked and adjusted after installation to ensure optimal handling and tire wear. The bushings can be installed with the vehicle on a lift or safely supported on jack stands.
