This is a great lubricant for the 300ZX R230 or R200 differentials.
This is the preferred product in nearly all car and light truck differentials, both conventional and limited-slip. 75W90 is preferred for most racing applications. It contains friction modifier which is recommended for limited-slip units. 75W90 Gear Oil can be used in many transmissions and transaxles; however, other Red Line lubricants have better frictional properties for rapid synchronization. Exceeds API GL-5.
2 Required for 300ZX, 350Z, 370Z, G35, & G37.
