Mahle Rings Dodge Trk 238 3.9L Eng 86-91 Moly Ring Set

This set includes the moly piston rings you need to rebuild the engine in a variety of Dodge trucks and vans from the late 80s and early 90s. Specifically, these rings are designed for 3.9L engines found in models like the Dodge Dakota, B150, and D150, covering years from 1986 through 1991. Piston rings are crucial for sealing the combustion chamber, controlling oil consumption, and transferring heat from the piston to the cylinder wall. Mahle OE rings are built to meet the demanding requirements of original equipment manufacturers.

Mahle's approach focuses on reducing friction within the engine, which can lead to improved efficiency and a longer service life for your engine components. By minimizing oil consumption, these rings help keep your engine running cleaner and prevent issues related to excessive oil burning. The moly coating on these rings helps with initial break-in and provides a durable surface that works well with the cylinder walls.
