261XHD, 263XHD Transfer Case Pump Upgrade Combo, LB7 LLY LBZ, 2001-2007

The Merchant Automotive Transfer Case Pump Upgrade is the best upgrade you can perform on your 2001 to early-2007 GM transfer case by completely preventing the ever increasing problem of pump rub and catastrophic transfer case fluid loss. The basic kit can be installed proactively in a transfer case that has not yet succumb to a pump rub failure as a preventative maintenance measure. If your transfer case has already had a pump rub failure the MA Transfer Case Pump Upgrade can be installed as part of your repair to prevent future failure.

This kit is designed to include the parts necessary to perform an upgrade and repair to a transfer case that has suffered a pump rub failure requiring replacement of the rear case half for vehicles using the NP261XHD and NP263XHD transfer cases with Duramax diesel LB7, LLY and LBZ engines as well as 8.1L gas engines when equipped with the Allison transmission. Note that transfer cases operated without lubrication may also have additional internal damage that will not be evident from external inspection and could require additional parts. When properly installed this kit is backed by a Limited Lifetime Warranty against pump rub failure from Merchant Automotive.
