Ford Racing Super Duty Limited Slip Front Differential

Specifically formulated for clutch-type limited-slip differentials, this friction modifier from Ford Racing is designed to work with your Super Duty's front differential. When you're dealing with a limited-slip unit, especially in a heavy-duty truck like your F-250 or F-350, ensuring smooth engagement is key to a comfortable and controlled driving experience. This additive is intended to be mixed with your differential fluid to help achieve that.

The main job of this friction modifier is to reduce the tendency for clutch-type limited-slip differentials to chatter during low-speed turns or when the vehicle is under load. By providing consistent friction characteristics between the clutch plates inside the differential, it allows them to slip and engage smoothly as needed. This not only makes for a more pleasant driving experience but also helps protect the internal components of your differential from excessive wear caused by inconsistent engagement. It's a simple way to fine-tune the performance of your existing limited-slip setup.

To get the most out of this friction modifier, it's important to follow the manufacturer's recommended dosage and mixing procedure. Typically, these additives are mixed directly into the differential fluid before it's filled into the axle. Always refer to the product's instructions or your vehicle's service manual for the correct amount to add to ensure optimal performance and longevity of your front differential.
