Description

Protect your GM 6.6L Duramax transfer case from costly internal damage with the PPE Heavy-Duty Transfer Case Pump Upgrade Kit. Designed to permanently eliminate the infamous “pump rub” issue found in many GM 4x4 transfer cases, this precision-engineered kit replaces the weak OEM components that wear through the case and cause fluid loss.

PPE’s upgraded machined aluminum pump cover securely supports the oil pump, preventing movement that leads to housing wear. Each kit includes everything needed for installation—complete with gasket and thread locker—ensuring long-lasting reliability and leak-free operation. Whether restoring or upgrading your truck, this PPE kit provides the peace of mind and durability your Duramax deserves.
