Superior quality Pinion & Slip Yokes are available for your 2004.5-2007 Dodge 5.9L Cummins. While pinion yokes aren't damaged often, they are susceptible to damage from abuse with burnouts, drag racing, and less-ideal driveshaft angles in lifted applications. Pinion flanges, seals, bearings, and shim kits are offered for most applications. There are top-notch brands available, including Dorman and Nitro Gear & Axle.
