Whiteline's front differential Positive Power kit for 2008+ Subaru Impreza, WRX, and STi applications replaces factory differential bushings to maintain pinion angles and improve gear shift feel while reducing initial torque loss for better power transfer to the wheels. Built with Whiteline's synthetic elastomer and protective plated metal components, the kit resists oil, grease, ozone, and weathering. It includes internal grease reservoirs for continual lubrication, extreme-pressure moly grease, and an install guide.
