The B4s are Bilstein’s replacement shock absorbers for standard vehicles. These entry-level shocks are designed as direct replacements for your old, tired and potentially leaking factory shocks. Made in Germany by the best in the business, there is nothing cheap about the build quality, nor the way your BMW will drive under a new set of these shocks. The perfect solution for most people, they will restore the finesse and suspension damping to back to how your car did when it rolled out of the factory.
Helpful tips
The shock absorbers fitted to your car from the factory have a relatively short life before they fall out of there efficacy range and fail to deliver the same damping abilities they once did. Replacing yours will not only overhaul your car’s handling and comfort, but its safety as well.
