Fits select 1992-2006 BMW 3 Series (E36, E46) and Z3 models.

SPL Parts FKS Series Rear Upper Arm Bushings (RKB) replace compliant factory rubber bushings with high-precision, low-friction articulating spherical bearings. By eliminating bushing deflection and reducing friction-induced bind, these monoball replacements maintain optimal suspension geometry under heavy cornering or braking loads. This ensures consistent camber and toe settings for more predictable handling and improved driver feedback.

Engineered for high-performance use, these bushings are a direct replacement for the OEM components, providing a significant upgrade for track-driven vehicles and performance enthusiasts. The CNC-machined aluminum shells ensure an exact press-fit into the factory arms.
