9-inch Rearend Oil Service/Install Kit

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 the life of all drive components
• Meets or exceeds: API GL-6 (designed for 9-inch gears)

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

Oil Capacities
The following are estimations of oil capacities for Currie^® axle assemblies. Extreme pinion angles 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.
