Diesel Piston Rings

Not sure which part you need? Use our parts-request checklist.

Diesel piston rings seal combustion pressure, control oil, and transfer heat from the piston to the cylinder wall. When rings wear, you see blow-by, oil consumption, and lost power, which is why fresh rings are at the heart of any honest rebuild. JAK'S Diesel stocks compression and oil-control rings for heavy-duty and Class 8 engines, including PAI Industries aftermarket sets.

Match rings to your bore size and finish, and order them as part of a complete kit. Not sure which set fits your block? Send us your engine and part numbers and we'll cross-reference it.
