Review FORD PERFORMANCE Super 8.8 Inch 34 Spline Traction-lok Differential for MUSTANG 2015–2024

Introducing the Ford Performance FMS-M-4204M 2015-2024 Mustang M-4204-M 8.8 34 Spline Traction-Lok Differential, an essential upgrade for Mustang enthusiasts seeking improved handling, traction, and performance. This differential, manufactured by Ford Performance, is designed specifically for the 2015-2024 Mustang models to replace the stock unit.

The M-4204-M Traction-Lok differential is an upgrade from the standard open differential, offering several advantages.

The M-4204-M Traction-Lok differential also includes an improved differential cover with a baffled design. This design helps prevent oil starvation during high-performance driving, ensuring optimal cooling and lubrication. The cover is also made of aluminum, which is lighter than the stock steel cover, contributing to weight reduction and improved performance.

Additionally, the M-4204-M Traction-Lok differential includes a revised pinion yoke and upgraded ring and pinion gears. These upgrades result in better torque transfer and reduced power loss, ultimately leading to improved acceleration and overall performance.

In summary, the Ford Performance FMS-M-4204M 2015-2024 Mustang M-4204-M 8.8 34 Spline Traction-Lok Differential is an excellent upgrade for Mustang owners seeking enhanced handling, traction, and performance. With its limited-slip design, robust 34 spline shafts, improved differential cover, and upgraded gears, this differential delivers superior power transfer and durability, making it an essential addition to any Mustang enthusiast's build.

2. Installation Complexity: Installing the Traction-Lok differential requires a fair amount of mechanical knowledge and expertise. It is not a simple bolt-on upgrade and can be time-consuming and labor-intensive.

3. Noise: Some users have reported an increased noise level when using the Traction-Lok differential. This can be due to the differential's design and the increased power being transferred to the wheels.

4. Limited Compatibility: The Ford Performance Traction-Lok differential may not be compatible with all Mustang models or configurations. It is important to ensure that the differential is compatible with your specific vehicle before making a purchase.
