Eliminate rear-end instability and restore precise handling with these solid monoball rear trailing arm bushings (RTAB), engineered for BMW E36, E46, and Z4 platforms. Designed to replace the factory rubber bushings, this upgrade removes unwanted deflection and rear-steer under braking, acceleration, and hard cornering.
Factory rubber RTABs deteriorate over time, especially on vehicles with increased power, upgraded suspension, wider tires, or aggressive driving. These monoball bushings lock the trailing arm firmly to the chassis, delivering consistent toe control and a noticeably more planted rear end.
Important Notes:
These bushings are a proven solution for drivers who demand sharper handling and consistent rear suspension geometry. Whether you’re correcting worn factory components or building a more track-focused setup, this upgrade delivers confidence where it matters most.
Lock in your rear alignment and feel the difference immediately.
