After a hundred thousand kilometres of washboard and frost-heaved pavement, a Crosstrek on tired factory struts starts to float over dips and nose-dive under braking. The Bilstein B4 Strut & Shock Set swaps all four corners at once with twin-tube, gas-pressure dampers built as direct OE replacements, so the ride height and handling feel stay where Subaru intended. Each set includes a left and right front strut assembly with a fixed spring seat plus two rear shocks, and it reuses your Crosstrek's factory springs and top mounts. Sets are listed for 2013-2017 (including the XV-badged 2013-2015 cars), 2018-2019 and 2021-2023. It is a sensible refresh for a commuter that spends Alberta winters on salted roads. Canada-wide shipping from Flat 4 Offroad in Calgary.
