Fit all-terrain tires and a roof rack to a Crosstrek and the soft factory damping starts to feel vague, with extra body roll and a rear end that keeps moving after rough patches. The Bilstein B6 Strut & Shock Set firms that up without changing ride height, pairing twin-tube front strut assemblies with monotube gas-pressure rear shocks and Bilstein's digressive, velocity-sensitive valving. Sets are offered for 2013-2017 models, XV badge included, and for the full 2018-2023 generation. Your stock springs and top mounts carry over, and the fronts include a fixed spring seat. On Alberta gravel roads the Crosstrek tracks straighter and settles faster after washboard. Flat 4 Offroad ships it Canada-wide from Calgary.
