Currie TwinTrac, Truetrac, and Wavetrac Explained- Helical gear limited-slip type differentials (HGLSD). The HGLSD is the modern replacement for the classic clutch-style limited-slip. When cruising, HGLSDs function like a standard or open differential, allowing one wheel to spin faster or slower as necessary without the noise or stick-slip frequently experienced with clutch-style limited slip or automatic locking differentials. Under acceleration, if a wheel loses traction, the helical gears inside the differential automatically engage, transferring torque to both rear wheels. When the wheels regain traction, the HGLSD seamlessly transitions back to functioning as an open differential. Unlike the traditional clutch-type limited-slip, HGLSDs require no special oil additive or maintenance to replace worn and tired clutches. HGLSDs have no wearable parts, require no special oil additive or maintenance, and maintain their as-new functionality for life. THIS LISTING IS FOR A TWINTRAC

Master Bearing Kit
High-quality Timken or Koyo bearings and performance seals are used throughout to provide a long, trouble-free service life
 
Gear Ratio

Lubrication Requirements - 9-inch rear-ends use a high-offset hypoid gear design that requires a severe duty 85w-140 gear oil with API GL-6 rating. Use of oil not meeting the GL-6 rating will damage the gears and bearings and void the Currie Warranty
