Currie 85W-140 GL-6 Racing Gear Oil

PRODUCT OVERVIEW

High-performance non-synthetic racing gear oil meets the API GL-6 specification and is 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.

Oil Capacities:
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.
