FAQ
Is the price per piston or for a full set?
CPP Diesel lists this as a complete set of eight (8) pistons with rings.
What does “reduced compression height” mean on this piston?
The compression height is .010" shorter than stock to help control cylinder pressure in towing or tuned applications while keeping OE geometry.
Do I need machine work for .030" over?
Yes—have your block bored/honed to +.030" and set piston-to-wall clearance per MAHLE spec.
Are the skirts coated?
No—this configuration uses non-coated skirts.
