BMW 4 Series Rear Traction Arm Knuckle Bushing - SPL Parts - Spherical. Replace the factory rubber with a Teflon-lined spherical bearing for precise, consistent rear suspension control.

Designed for the lower control arm-to-knuckle on F3X 4 Series (F32/F33/F36), this bushing cuts deflection under load and reduces bind through suspension travel. The 6061-T6 aluminum housing is CNC-machined to +/- .001 for proper fit, and the largest feasible FK bearing helps longevity while keeping NVH in check. Sold as a pair. Made in the USA.
