Chrys/Dodge Spring Bush SS SPG B&E

The Chrys/Dodge Spring Bush SS SPG B&E by PROTHANE is a rear leaf spring bushing kit engineered for classic Mopar B-Body and E-Body vehicles manufactured between 1965 and 1974. This polyurethane bushing assembly replaces worn or deteriorated OEM rubber components, restoring suspension geometry and eliminating unwanted chassis flex that develops over decades of road use. Spring bushings are critical suspension components that anchor leaf springs to the vehicle frame, and their degradation directly impacts ride quality, handling response, and long-term structural integrity.

Constructed from durable polyurethane material in a black finish, this bushing kit offers superior resilience compared to aged rubber alternatives while maintaining compliance for smooth ride characteristics. Polyurethane bushings resist UV degradation, ozone cracking, and oil exposure far better than factory elastomer, extending service life significantly in both street and show car applications. The material's controlled deflection rate preserves the intended suspension kinematics designed into these classic platforms, preventing the soft, wandering steering and excessive body roll associated with failed rubber components. Installation requires basic mechanical skill and common hand tools, making this kit accessible to dedicated enthusiasts and professional restoration shops alike.

Restorers, vintage car collectors, and Mopar enthusiasts pursuing complete suspension renewal will find this spring bush kit essential for vehicles requiring rear suspension system updates. This kit addresses a known wear point in first-generation B-Body and E-Body platforms, including Dodge Charger, Coronet, Road Runner, and Plymouth Satellite models. Whether undertaking a frame-off restoration or refreshing aging suspension geometry on a driver-quality classic, these polyurethane bushings deliver reliable performance and improved handling feedback that transforms the driving experience on these iconic American muscle cars and full-size sedans.
