Product Description
MAHLE 224-3523WR marine-bowl piston set with rings (STD bore) for the 1994–1998 Cummins 5.9L 12-valve. Built to OE specs with 40 mm wrist pins, expansion-controlled design, and a factory-matched ring pack, these pistons deliver durable sealing and the proven marine/QSB-style bowl for mixture quality under load.
Why it wins: consistent ring loading, oil control under heavy towing, and stable skirt geometry. The marine bowl helps concentrate heat where it belongs and supports clean burn when fueling is increased.

FAQ
Is this priced per piston or for a full set?
CPP Diesel sells this as a complete set of six (6) pistons with rings.
 Will these drop into my 1994–1998 12-valve?
Yes, this STD-bore set is intended for ’94–’98 5.9L 12V builds. Always confirm cylinder bore, pin size (40 mm), and bowl spec before installation.
 What’s the difference between marine-bowl 224-3523WR and standard-bowl 224-3520WR?
The marine/QSB bowl concentrates the combustion area versus the standard bowl. Choose 224-3523WR for marine-bowl builds; choose 224-3520WR for OE-style standard bowl.
 Do the rings come pre-installed?
Rings are included and should be sized/gapped and installed per MAHLE/Cummins spec during assembly.
