Detroit Truetrac 09- 31 Spline Ford F150 8.8

DETROIT LOCKER-TRACTECH Differential Carrier - Detroit Truetrac - 31 Spline - Steel - Ford 8.8 in - Each. Features a patented design of parallel axis, planetary helical gears, which ensures a seamless and noiseless automatic distribution of torque. The Truetrac engages and disengages without any driver action required. This smooth power transfer is imperceptible to the driver, even in front-wheel-drive axles. Notably, the Truetrac’s smooth operation does not impact braking characteristics or fuel consumption. It also has no wearable parts and requires no maintenance. In typical driving scenarios, the Truetrac Differential functions akin to an open differential. However, when encountering challenging conditions like wet, muddy, icy, or loose terrain, its design automatically redirects power to the wheel with the highest traction. This instantaneous response to torque feedback results in necessary traction at any speed. The Eaton Detroit Truetrac excels in both front and rear axles, so it offers versatile performance. Its proven design, coupled with cost-effectiveness, positions it as not only a great choice for the F-150, but also a wide array of vehicle applications. For optimal Truetrac performance, the company recommends using a quality petroleum-based GL5-rated gear oil with a viscosity grade of 80W-90. Synthetic oils are not recommended. Additionally, friction modifiers should not be used as they can negatively impact overall performance by reducing the differential bias.
