What is the purpose of a friction plate in a differential?

A friction plate helps manage the slip action within a limited-slip differential. It sits within the clutch pack and controls how much the wheels can spin independently, ensuring power is sent to both wheels when needed.

Does this friction plate come with other parts for the clutch pack?

This listing is for a single-sided friction plate only. Clutch packs typically include multiple friction plates and steel plates; you may need to purchase additional components separately to complete a full clutch pack rebuild.

What specific Ford differentials does this friction plate fit?

This friction plate is designed for Ford's 8-inch and 9-inch Trac Loc differentials. It is compatible with a range of Ford vehicles from the late 1950s through the late 1980s.

Product Details

This Yukon Gear & Axle friction plate is made with a graphitic material, which helps it handle the friction and heat generated within a limited-slip differential. It's a single-sided, 4-tab design, specifically intended to work with Ford's Trac Loc posi-traction units found in their 8-inch and 9-inch rear ends.

When you're rebuilding or servicing a Ford differential, especially one with a Trac Loc unit, these friction plates are a key component. They sit between the clutch packs and help manage the slip action, which is crucial for getting power to both wheels during turns. Yukon Gear & Axle is known for making a lot of the small, essential parts that go into differentials, and this plate is no exception. It's built to fit right into the specified Ford applications, making the job straightforward.

This part fits a wide range of Ford vehicles from the late 1950s through the late 1980s, including popular models like the Ford Bronco, F-100, and Mustang. Make sure to check the full fitment list to confirm it's the right piece for your specific application.
