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. 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, 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 upgrade drops directly in place of your stock differential on your 2009-2025 F150 with 8.8" IFS front ends and 31-spline axle.
