Larsen Racing Products is very proud to offer a quality gear oil for the Platinum Track Differentials. This is a full synthetic gear oil designed specifically for our race differentials. This particular oil reduces friction for maximum power transfer in a fully synthetic design for superior protection. The Platinum Track Race Differential is designed with preload; this oil keeps critical parts separated with film strength to absorb extreme shock loads. This oil is great to run in any differential and is an excellent choice for all hypoid gear systems. In addition, this oil exceeds the requirements of API GL-5. Sold in 1 gallon containers only.
