      Enhanced Driveshaft Connection. Restore an OEM-like performance on your 2015-2021 Ford Mustang V6, EcoBoost, or GT by installing Ford Performance Automatic Transmission Rear 8.80 Inch IRS Pinion Flange. This flange is a direct replacement for your Mustang’s worn-out and leaking stock flange. It is engineered to ensure that the vehicle’s driveshaft is performing flawlessly. It guarantees smooth automatic gear transmission thus ensuring optimal performance both on the race track, and the highway.

      Convenient Design. Ford Performance designed this IRS pinion flange to OEM specifications. It therefore works with existing driveshaft components without requiring additional installations. In addition, the pinion flange is a direct fit replacement part, and thus, negates the need to tear down your Mustang’s entire driveshaft system when installing it.

      Built to Last. High-strength steel was used to build this pinion flange. Therefore, it can withstand years of abuse without affecting your Mustang’s performance. The pinion flange similarly has a natural metallic finish, which provides additional resistance to corrosion and rust, thus ensuring years of steadfast service.

      Professional Installation. Although the Ford Performance Automatic Transmission Rear 8.80 Inch IRS Pinion Flange mounts directly to your Mustang, considerable mechanical expertise is required to install it. You need to ensure that it is expertly connected to other driveshaft components to guarantee reliable operation. Installation requires simple tools and lasts approximately 2 hours.

      Warranty. Ford Performance backs the flange with a 12-month warranty against structural defects.

      Application. The Ford Performance Automatic Transmission Rear 8.80 inch IRS Pinion Flange fits all 2015 to 2021 Ford Mustang GT, EcoBoost, and V6 models.
