Construction & Design

BMR Suspension utilizes Delrin, a high-performance thermoplastic, to manufacture these bushings. Delrin offers an excellent balance of rigidity and durability, outperforming traditional rubber bushings by maintaining shape and resisting deformation under stress. This material choice ensures consistent suspension geometry and alignment, even under aggressive driving conditions. The bushings are precision-machined to exact OEM specifications, guaranteeing a perfect fit and seamless integration with your vehicle’s rear lower control arms.

The design focuses on reducing unwanted movement while preserving enough compliance to avoid harshness, delivering a refined yet responsive ride quality. BMR’s engineering expertise ensures that these bushings withstand the rigors of daily driving and track use alike.

Installation & Fitment

The BMR Rear Lower Control Arm Bushing Kit is designed as a direct replacement for the factory rear lower control arm bushings on Chrysler 300 and Dodge Challenger models from 2005 through 2024. Installation requires basic mechanical skills and standard hand tools.
