The Whiteline differential mount insert is a rear traction-control bushing designed for Nissan 350Z and Infiniti G35 applications to help maintain pinion angles and improve gear shifting for better power transfer. Its synthetic elastomer resists oil, grease, ozone and weathering; inserts work with the original factory bushing and include internal grease reservoirs plus supplied molybdenum disulphide grease and an install guide.
