Superior quality Pinion & Slip Yokes are available for your 2011-2016 Ford 6.7L Powerstroke. Pinion flanges, seals, bearings, and shim kits are offered for most applications. While pinion yokes don't require replacement in all applications, they are susceptible to abuse with damage from things like burnouts, drag racing, and extreme driveshaft angles from lifted applications. There are top-notch brands available, including Dorman and Nitro Gear & Axle.
