Heavy-Duty Transfer Case Pump Housing Upgrade Kit 129001000 (Pump Rub Kit) for GM Allison - Durable Replacement Part for Off-Road Trucks & Commercial Vehicles

Cure the dreaded “pump rub” with Pacific Performance Engineering’s (PPE) Transfer Case Pump Upgrade Kit. Pump rub occurs when the four positioning tabs holding the pump in place wear over time. This causes the oil pump to come into contact with the housing itself. The result is a hole worn in the cover, causing fluid to leak and the probability of damaging the transfer case. This simple kit eliminates this problem. The main benefit of using this kit is a more secure method of supporting the pump and better distributing the load, to eliminate the dreaded “pump rub". PPE’s kit contains a gasket, thread locker, a machined billet aluminum pump cover, and a high-power Neodymium Ring Magnet to attract and hold harmful ferrous metals.
