The Ford S209-C Mustang GT Rear End Differential (Part Number: 121250178J) is a high-performance component designed specifically for the S209 variant of the iconic Ford Mustang GT, manufactured between the years 2013 and 2014 (S197 platform). This differential is an essential upgrade for enthusiasts seeking improved power delivery, enhanced traction, and superior handling in their performance-oriented Mustang.
The S209-C Rear End Differential is engineered with a unique 3.73:1 final drive ratio, providing optimal balance between acceleration and traction.

The differential's high-strength steel construction offers exceptional durability and resistance to wear and tear, ensuring reliable performance even under the most demanding conditions.
One of the standout features of this differential is its Torsen limited-slip design.

The Torsen differential's self-adjusting clutch pack ensures consistent engagement and disengagement, reducing the likelihood of power loss and promoting optimal tire grip.
The S209-C Rear End Differential also features a helical gear design, which is smoother and quieter than traditional spiral gear designs. This helps to reduce noise and vibration, providing a more comfortable driving experience while maintaining the differential's performance capabilities. Additionally, the helical gear design reduces the differential's rotational mass, resulting in quicker acceleration and improved response times.
Installing the S209-C Rear End Differential is a straightforward process, thanks to its easy-to-follow installation instructions and compatible bolt patterns. This differential is a direct replacement for the stock differential, making it a hassle-free upgrade for Mustang enthusiasts looking to enhance their vehicle's performance.
