Mustang 113mm IRS Pinion Flange Kit
Replace your Mustang's defective IRS pinion seal with this OEM style 2015-2017 Mustang 113mm IRS Pinion Seal Kit from LMR.com! This quality Ford original pinion flange is great for replacing worn or damaged pinion flanges or to swap in 2018+ differential housings into 2015-2017 Mustangs equipped with the MT82 transmission. Replacing your pinion flange is a great way to ensure new gear installs will not have leaks from the pinion seal from an old pinion flange!
Installation of Ford Performance loaded differential housings with the part number M-4001-88355B will require 2015-2017 Mustangs equipped with MT82 transmissions to purchase this flange for correct fitment. All loaded differentials from 2018+ will have the smaller pinion flange installed and will require this larger pinion flange for correct fitment on 2015-2017 MT82 equipped Mustangs.
