Show original supplier description
The Powerflex Front Radius Arm to Chassis Bushings are designed as a high-performance replacement for the factory bushings on specific BMW chassis models. By utilizing a 95A durometer Black Series polyurethane material, these bushings provide an 18% increase in stiffness over the original components, allowing the suspension to better withstand the increased loading experienced at this pivot point. These bushings are compatible with the following BMW models: F87 2 Series M2 (2016+), F80 M3 (2015-2018), and F82/F83 M4 (2015+). They serve as a direct replacement part, identified by OEM reference numbers 431 407 183 A, 31122284531, 31122284532, and 31122283579. Note that for owners requiring caster adjustment, Powerflex offers the PFF5-4001G version as an alternative to this non-adjustable kit.
