OE Rear Axle Jounce Bumpers for Lowered 1 Series and 2 Series

Enhance your suspension travel and protect your dampers with original rear axle jounce bumpers designed for the F-chassis 1 Series and 2 Series. Ideal for cars running lowering springs or coilovers, these factory rubber buffers control compression, reduce harsh bottoming, and keep your ride refined on British roads while maintaining sharp handling.

Perfect for F20 and F21 hatchbacks and F22 and F23 coupe and convertible models, including the popular M135i, M140i, M235i and M240i. If you are dropping your car below standard ride height, upgraded rear bump rubbers are a smart, simple and effective suspension upgrade.
