FAQs

Q: What is a Monotherm piston and why is it used?
A: Monotherm pistons are forged from a single piece of steel, offering superior resistance to high temperatures and pressures—ideal for EGR engines where traditional aluminum pistons may fail prematurely.

Q: How can I verify fitment for my engine?
A: Confirm your engine serial number and check if your ECM is DDEC V. You can also match the OEM part number 23538418 or HDKits number S60117-017.

Q: Can I choose piston and bearing sizes?
A: Yes. Please specify standard or oversize options for pistons, rod bearings, and main bearings during checkout or request.

Q: Is this kit suitable for an out-of-frame rebuild?
A: Yes, while it’s commonly used as an in-frame overhaul kit, it includes components that also make it suitable for full out-of-frame engine rebuilds.
