FAQ

Is this set per piston or for all six?
Sold per cylinder (one piston). Order six sets for a full 5.9L engine.
Will these fit both 12-valve and 24-valve 5.9L Cummins?
Yes—applications include 1989–1998 12V 6BT and 1998.5–2002 24V ISB, provided your cylinders are bored to .020" over and you’re using matching oversize pistons. Verify by ESN.
Can I use .020" rings on a standard bore?
No. .020" (0.50 mm) rings are for oversize bores only with matching .020" pistons after machining/honing.
What ring end gap should I use?
Follow the Cummins service manual for end-gap specs based on ring position and application.
What’s the warranty?
Interstate-McBee rings carry manufacturer warranty (commonly up to 2 years for new parts). Contact us for specific terms.
