The Bilstein B4 OE Replacement rear shock absorber for the 2013–2018 Ford Focus is a direct-fit damper from Bilstein's B4 OE Replacement line. It is built to bring a worn rear corner back to factory ride quality and handling, and it suits drivers who want the original damping feel without a coilover-style conversion. Choose it over a budget shock when you want a brand with a known OE-replacement pedigree and predictable, factory-like behavior on the road. Because the part is aimed at restoring the original setup, it is a practical upgrade for daily-driven Focus ST and hatch owners who are replacing a leaking or tired rear shock rather than chasing track-day stiffness. Fitment is listed for the 2013–2018 Ford Focus, with the ST submodel named in the application data. Confirm the fit against your VIN before ordering, and do not confuse this part number with Bilstein's separate 2012–2016 Focus rear pair. For replacement, search terms such as "Bilstein B4 Focus ST rear shock replacement," "13-18 Focus rear OE damper," and "Bilstein 19-249124 install" will bring up matching application and install guidance. Shocks are generally replaced in pairs on the same axle so both sides damp the same way, so plan to match the opposite side.
