FAQ
Yes. This kit covers 1998.5–2002 5.9L ISB (VP44), 2003–2007 5.9L ISB (common-rail), and 2007.5–2018 6.7L ISB Ram 2500/3500 applications that use the factory 24-valve cylinder head. For medium-duty or industrial ISB/QSB engines, confirm by Cummins ESN before ordering.
HOW MANY INTAKE VALVE KITS DO I NEED?The 24-valve ISB head uses 12 intake valves and 12 exhaust valves. This part number is sold individually per intake valve location, so you will need quantity 12 for a complete intake-side refresh on one engine.
WHAT EXACTLY IS INCLUDED IN CUMMINS 3802924?The 3802924 kit includes the correct OEM intake valve (3940735) and matching retainer/keeper hardware for that position. Valve stem seals are usually serviced separately – pair this kit with new seals, guides, and seats as needed for a proper cylinder head rebuild.
CAN I MIX THIS OEM VALVE KIT WITH AFTERMARKET VALVES?Best practice is to keep a matched set of valves per engine (or at least per bank) so stem weight, face geometry, and metallurgy are consistent. If you must mix OEM and aftermarket components, verify dimensions carefully and always reset valve lash after installation.
DO I NEED MACHINE SHOP WORK WHEN REPLACING INTAKE VALVES?It’s strongly recommended. Properly cut and blended seats, checked guide clearances, and new stem seals are key to valve life and compression. A quality valve job plus genuine Cummins parts usually outlasts a simple “valve swap” done without machine work.
WHY BUY THE CUMMINS 3802924 KIT FROM CPP DIESEL?CPP Diesel specializes in Cummins diesel platforms and stocks the supporting hardware you need (exhaust valves, head bolts, alignment dowels, rocker assemblies, and more). You get genuine parts, fast shipping, and tech-focused support from a team that lives and breathes ISB engines.
