Provides Enhanced Front-End Traction for F150s

One of the most popular upgrades in the aftermarket truck world is an upgraded differential, and the Eaton Detroit TrueTrac Front Limited Slip Differential is here to show you why. The Detroit TrueTrac will enable your tough 2009-2024 F150 to claw its way out of just about any situation all while maintaining on-road drivability and comfort. This Limited Slip Differential works by distributing power more evenly between the front two wheels, allowing them both to receive some power, even if one wheel starts to slip. Wheel slip is caused by low-traction surfaces, rapid acceleration or deceleration, uneven road conditions, or uneven weight distribution on your truck. When one wheel slips, the TrueTrac automatically engages to prevent the wheel from spinning excessively while the other has better traction, helping your F150 maintain better control in challenging conditions. This is particularly beneficial for wet and icy conditions, steep inclines, mud, gravel, and any other low-traction situations you find yourself in. Trucks used for towing and hauling will also benefit from the TrueTrac as it provides better stability and control when your truck is under a heavy load.

Added Versatility for any Adventure

The Eaton Detroit TrueTrac Front Limited Slip Differential offers a good balance between the improved traction of a locking differential and the maneuverability of an open or stock differential. A locking differential locks both wheels together on a single axle, creating more traction for uneven road surfaces at the cost of reduced mobility on paved surfaces. Locking differentials also tend to lead to increased tire wear, and cost much more than the versatile Limited Slip Eaton TrueTrac. On the other hand, an open or stock differential works fine for basic everyday applications, but it won't offer the increase in handling or control that comes with a Limited-Slip upgrade. Additionally, the Detroit TrueTrac has no wearable parts and requires no maintenance other than standard differential fluid changes. During normal driving, the TrueTrac operates like a standard differential to keep your street applications smooth and easy. Best of all, this upgrade drops directly in place of your stock differential on your 2009-2024 F150 with 8.8" IFS front ends and 31-spline axle.
