FAQ

Will this pin fit all 1989–2007 5.9L Cummins?

Dimensionally correct for 5.9L applications when paired with compatible pistons and rod bushings. Always confirm your piston and rod specs.

What does the DLC coating add?

DLC (diamond-like carbon) reduces friction/scuffing and improves wear life under high load and temperature.

Is the 9300738 sold as a single pin?

Yes—quantity is per pin. Order the correct count for your piston set.
