SPL Parts Rear Spherical Knuckle Bushing Kit - 2014-2016 BMW 428i (F32/F33)

The SPL Parts Rear Spherical Knuckle Bushing Kit is an aftermarket upgrade designed for the 2014-2016 BMW 428i (F32/F33). This kit replaces the factory rubber bushing that attaches the lower control arm to the knuckle with a high-performance, low-friction Teflon-lined spherical bearing. The use of spherical bearings reduces deflection under heavy loads and minimizes binding as the suspension moves through its travel, resulting in improved handling precision and responsiveness. Constructed with a machined housing to accommodate the largest FK bearing possible, this kit enhances durability and lowers noise, vibration, and harshness (NVH). It is engineered to provide a more direct connection between suspension components, offering increased control and stability during aggressive driving or track use.

Designed specifically for the rear traction arm of the F32/F33 chassis, this bushing kit is compatible with vehicles from 2014 to 2016. It serves as a direct replacement for the OEM rubber bushings, making it suitable for street, track, or performance-oriented applications. Installation involves replacing the stock bushings with these spherical bearings, providing a more precise suspension response. The kit includes all necessary components for a straightforward upgrade, ensuring a secure fit and long-lasting performance. Ideal for enthusiasts seeking improved handling and reduced suspension deflection, this bushing kit enhances overall vehicle dynamics and driving confidence.
