Currie Enterprises 9-Inch Racing Gear Oil

High-performance non-synthetic racing 85W-140, gear oil meets the API GL-6 specification designed specifically for the requirements of 9-inch gear assemblies. It provides maximum shear stability and extreme pressure protection required to extend the life of your Currie rearend.

9-Inch API GL-6 Requirement

Due to the high-offset hypoid design (very high shear) of the 9-inch ring and pinion gears, a severe duty petroleum-based gear oil with API GL-6 specification is mandatory. The use of synthetic or GL-5 specification gear oils will result in premature wear of the gears and excess heat buildup that will damage internal components, voiding the Currie Warranty.

The following are estimations of oil capacities for your new 9-inch and Currie® axle assemblies. Extreme pinion angles, as well as aftermarket components (such as diff covers),  may drastically change the unit’s capacity.
