Currie Racing Gear Oil Features & Benefits
- Premium petroleum-based racing-grade formula
- Excellent thermal and shear stability
- High shock load and extreme pressure chemistry
- Extends life of all drive components
- Meets or exceeds: API GL-6
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.
Currie 9-inch ....................................2.84 liters / 3 qts.
Currie F9 3 or 3.25 in. tube.................3.79 litres / 4 qts.
Currie F9 3.5, 4 or 4.5 in. tube............4.73 liters / 5 qts.
Currie Independent Center..................2.11 liters / 2 qts.
If you have a clutch-type limited-slip differential, a friction modifier additive must be used in addition to this oil.
