Description

The Merchant Automotive Transfer Case Pump Upgrade is designed to completely prevent the ever-increasing problem of pump rub and catastrophic transfer case fluid loss in 1998 to early-2007 GM transfer cases. It can be installed proactively or as a repair for cases that have already experienced pump rub failure. The kit is for vehicles using NP136, NP149, NV149, NP236, NP246, NP261, NP261HD, NP263, and NP263HD transfer cases with gas engines. It comes with a Limited Lifetime Warranty against pump rub failure when properly installed with a new rear housing.
