Bilstein 22-306609 B4 Front Left LH Suspension Strut for BMW G20 G21 G81 G22 G23

Refresh your BMW’s front end with the Bilstein B4 left-hand front suspension leg, part number 22-306609. This OEM-grade, gas pressurised twin-tube strut brings back tight steering response, confident road holding and smooth ride comfort on British roads. It is a straight swap for the passenger-side front unit on select G-series BMW 3 Series and 4 Series models running standard suspension without adaptive damping or electronic ride control.

We fit these B4 units on our own builds and for customers who want factory feel with long-term reliability. Feedback has been excellent for stability under braking, grip in wet weather and day-to-day comfort on UK tarmac.

Why this Bilstein B4 is a smart choice
