Bilstein B4 08-13 Smart Fortwo Front Twintube Strut Assembly - 22-145697

The Bilstein B4 Front Twintube Strut Assembly (part number 22-145697) is an OE-replacement suspension component engineered specifically for the 2008–2013 Smart Fortwo. Designed by one of the most respected names in performance and replacement dampers, the B4 series is Bilstein's answer for drivers who want to restore their car's original ride quality, handling precision, and safety characteristics without compromise. Whether your factory strut is worn, leaking, or simply past its service life, this direct-fit replacement brings your Fortwo back to the standard it was built to meet.

Key Features & Benefits

• OE Replacement Engineering: The B4 series is specifically engineered to meet or exceed original equipment standards, meaning you get a strut that restores factory ride quality rather than altering it — ideal for drivers who love how their Fortwo drives and simply want it to feel new again.
• World-Famous Bilstein Quality: Bilstein has built a global reputation for damper engineering. The B4 line brings that same pedigree to everyday OE replacement applications, giving you peace of mind that the part under your car is built to last.
• Twintube Gas-Pressurized Design: The twintube construction is a well-proven design that balances a compliant, comfortable ride with consistent damping performance — the right choice for daily driving and urban commuting in the Smart Fortwo.
• Direct-Fit Replacement: Engineered to fit the Smart Fortwo's front suspension mounting points exactly, so installation follows the same process as replacing the original strut — no modification, cutting, or adaptation required.
• Restores Handling & Safety: Worn struts reduce tire contact and increase stopping distances. A fresh B4 replacement strut restores proper suspension geometry and tire contact, bringing your handling and braking back to factory spec.
• Broad Trim Compatibility: Fits multiple Smart Fortwo trim levels and body styles across the 2008–2015 model range (see Fitment section below for specifics), making it a versatile part for owners of base, Passion, and Brabus variants alike.
