Mahle SS45902 Valve Stem Oil Seal Set

Mahle SS45902 is an engine valve stem oil seal set built for exhaust valve service on select Dodge Ram 2500 and Dodge Ram 3500 diesel applications. It uses a metal body with molded rubber sealing material to help maintain a consistent seal at the valve stem and support proper oil control in the cylinder head.

Key Features

  • Engine valve stem oil seal set for exhaust valve applications
  • Metal with molded rubber construction for sealing durability
  • Upper inside diameter: 6.2 mm
  • Inside diameter: 0.244 in
  • Outside diameter: 0.637 in
  • Stem overall height: 0.559 mm

Detailed Description

Mahle SS45902 is engineered for 1998-2002 Dodge Ram 2500 and 1998-2002 Dodge Ram 3500 exhaust valve stem service, with fitment noted through engine # 46239409. The seal dimensions are specified for accurate valve stem fitment, including a 0.244-inch inside diameter, 0.637-inch outside diameter, and 0.022-inch thickness. For technicians working on Dodge Ram 2500 diesel and Dodge Ram 3500 diesel cylinder head repairs, this part number provides a direct sealing solution for the exhaust side of the valvetrain. This part cross-references Fel-Pro SS 70937 for the same application.

What It Helps Address

  • Oil leakage past the valve stem seal
  • Excessive oil consumption from worn exhaust valve seals
  • Blue exhaust smoke caused by valve guide sealing wear
  • Oil fouling in the combustion chamber
  • Loss of proper top-end sealing during cylinder head service

Installation Notes and Tips

Verify engine number and exhaust-valve application before installation. Match the seal dimensions to the valve stem and guide specification during cylinder head service on Dodge Ram 2500 and Dodge Ram 3500 models. Clean the valve stem and guide area thoroughly before fitting the seal to help ensure proper seating and sealing performance.

Quality Assurance

Mahle gaskets and sealing products are used by OEMs and technicians worldwide, and SS45902 follows that OE-focused approach to engine sealing components.
