Advanced limited slip differential for enhanced traction and performance.
The Eaton Detroit Truetrac is a helical gear-type limited slip differential designed for the AMC 20 axle. This differential features a patented design that utilizes parallel axis, planetary helical gears, ensuring a smooth and quiet automatic division of torque. The Truetrac operates effectively under various driving conditions, providing improved traction on wet, muddy, icy, or loose surfaces by automatically transferring power to the wheel with the highest traction. This capability enhances vehicle handling and limits wheel spin-out, making it suitable for a range of applications including road racing and off-road competition.
With a spline count of 29 and compatibility with gear ratios of 3.08 and higher, the Truetrac is engineered to respond instantly to torque feedback, delivering necessary traction at any speed. Its design allows for efficient operation in both front and rear axles, as well as transfer cases. The Truetrac's performance is comparable to that of an open differential under normal conditions, while its advanced technology ensures that it meets the demands of various vehicle types, including emergency vehicles and commercial trucks.
Eaton's proven track record in producing reliable traction differentials is evident in the Truetrac's performance. The differential is designed to transfer up to 3.5 times more torque to the high traction wheel, making it a cost-effective solution for enhancing vehicle performance. The combination of its robust design and effective functionality makes the Truetrac a preferred choice for those seeking improved traction and handling in diverse driving environments.
