Ford Racing 04-17 F-150 4x4 8.8inch Front Axle Limited Slip Torsen Differentials

This is the Ford Racing Torsen limited slip differential specifically for the 8.8-inch front axle found in 2004-2025 Ford F-150 4x4 trucks. If you're looking to improve traction and put power down more effectively, especially when one wheel might lose grip, this differential is a solid upgrade. It's designed to ensure your engine's power is transferred to the wheels that have the most traction, making a noticeable difference on the street, at the drag strip, or when you're off-road.

What sets the Torsen design apart is its worm gear friction system. Unlike traditional clutch-type limited slip differentials that can wear out over time, the Torsen unit uses torque-sensing and biasing to manage power distribution. This means it responds immediately to changes in driving conditions, smoothly engaging to send power where it's needed without the jerky feel you might get from other designs. It's a full-time torque-sensing unit that's built to last and perform consistently.

This differential is a 31-spline unit designed for the 8.8-inch ring gear found in the front axle of your F-150. While the manufacturer description doesn't detail what else is needed for installation, typically a differential replacement involves new fluid, and potentially seals or bearings depending on the condition of your axle. It's always a good idea to consult the manufacturer's installation instructions or a trusted mechanic to ensure you have everything required for a smooth swap.
