The 2015-2017 Ford Mustang GT 15 Posi Carrier Ring Pinion 3.15 is an essential component for any enthusiast looking to enhance the performance of their vehicle. This ring and pinion set is specifically designed for the Ford Mustang GT's limited-slip differential, providing superior traction and control.
The 3.15 ratio of this ring and pinion set offers a balanced combination of acceleration and top speed. With a higher gear ratio, this set is ideal for those who prioritize quick acceleration and powerful launches, making it an excellent choice for drag racing or street performance.
The Posi carrier itself is a crucial element of the limited-slip differential system. It utilizes a clutch pack that engages when power is applied, allowing the wheels with traction to spin at a different speed than the wheel without traction. This results in improved cornering and overall stability, especially during high-speed maneuvers.
Made from high-quality materials, this ring and pinion set is designed to withstand the rigors of high-performance driving. The ring gear is made from heat-treated steel, ensuring durability and resistance to warping under heavy loads. The pinion gear, on the other hand, is precision-machined for smooth operation and optimal tooth engagement.
Installing this ring and pinion set is a straightforward process, thanks to the included mounting hardware and detailed installation instructions. However, for best results, it is recommended to have this work done by a professional mechanic or at a reputable automotive shop.
In summary, the 2015-2017 Ford Mustang GT 15 Posi Carrier Ring Pinion 3.15 is a top-tier performance upgrade for your Mustang GT.
