Find the Pinion & Slip Yokes you need to get your 2006-2007 Chevy/GMC 6.6L LLY/LBZ Duramax back on the road. While pinion yokes aren't a common failure item, damage from broken shafts or u-joints, abuse from things like burnouts and racing, and less-than-ideal driveshaft angles can cause them to fail or break. Pinion flanges, seals, bearings, and shim kits are offered for most applications. There are top-notch brands available, including Dorman and Nitro Gear & Axle.
