Lift a Subaru WRX for gravel and the rear trailing arms become a target for every rock the front tires miss. LP Aventure Trailing Arm Shields are laser-cut 304 stainless steel covers that take those strikes instead of the arms. LP Aventure lists confirmed fitment for the 2022 WRX only, so check your model year before ordering. They are sold as a pair. Stainless means no rust bloom after a winter of Calgary road salt. Flat 4 Offroad ships them from Calgary across Canada.
