FAQ
How many pistons are included?
The price is for a **set of 6 pistons with rings**—enough for a full engine set.
Will this fit my 5.9L Cummins?
Yes—this kit fits 1989-1998 Cummins 5.9L 12-valve engines with marine bowl heads. Must be intercooled for 1991-1993 models. Not compatible with standard (non-marine bowl) heads without verification.
Is .040 oversize required?
Use .040 when rebored cylinder bores have been machined to that spec. Not for stock bore engines unless clearance measurement confirms need.
Are pins and clips included?
Yes—piston pins and retaining clips are included with the pistons and rings in this set.
