The Truetrac is the leading helical gear-type limited slip differential in the industry.

Eaton has a proven track record of producing the most effective and dependable traction differentials in the world. Truetrac's patented design of parallel axis, planetary helical gears, provides a smooth and quiet, automatic division of torque. Power transfer is so smooth, it literally goes unnoticed by the driver - even in front wheel drive axles. Because of Truetrac's smooth operation there is no affect on braking characteristics or fuel consumption.

Under normal driving conditions, Truetrac performs like an open differential. On wet, muddy, icy or loose terrain, imbalanced gear forces automatically transfer power to the wheel with the highest traction. The Truetrac limited slip differential responds instantly to torque feedback providing needed traction, anytime, at any speed. Engineered to work efficiently in front and rear axles, semi-floating (C-clip axles) and transfer cases. Proven design, low cost and effective performance, all make the Truetrac limited slip differential the ideal choice for a wide variety of vehicle applications, including emergency vehicles, walk-in vans, motor homes, SUVs, landscape and delivery trucks. Traction Control The Truetrac performs like an open differential under normal conditions, and automatically transfers torque to the wheel with the highest traction when required. The Truetrac can transfer up to 3.5 times more torque to the high traction wheel. This torque transfer ratio (called the bias ratio) is accomplished by using helical side gears and pinions. The bias ratio is the result of pressure exerted by the side gears and pinions against the surface of the differential case. In certain applications, this normal gear engagement may produce temporary driver feedback.
