On a Subaru Crosstrek, the rear differential is one of the lowest-hanging components, easily caught by rocks and ruts on rougher trails. ASFIR's Rear Differential Skid Plate shields it in laser-cut 1/4 inch aluminum, with drainage and ventilation built in to stop moisture from collecting against the housing. It bolts to the factory mounting points with no drilling required and doesn't cost you any ground clearance. Good insurance for anyone taking a Crosstrek beyond gravel roads into real backcountry driving. Ships from our Calgary shop Canada-wide.
