Superior quality Pinion & Slip Yokes are available for your 2004.5-2005 Chevy/GMC 6.6L LLY Duramax. 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. Whether you need pinion seals, bearings, shim kits, or flanges, you'll find what you're looking for. Industry-leading manufacturers like Dorman and Nitro Gear & Axle are available.
