FAQ
Is the price per piston or per set?
As a set these are only shipped in complete sets of eight for a full engine.
What’s different about “reduced compression”?
These use a .010" reduced compression height, commonly chosen when building for higher cylinder pressure or specific machining targets.
Are the skirts coated?
No—this part number is a non-coated skirt piston set.
Do the rings come installed?
Yes—this is a piston-with-rings set ready for assembly checks and installation.
Do I have to buy all eight?
Yes—full set (8) is required for shipment to ensure matched components across the engine.
Notes
- Verify block bore and deck height; professional measuring and machining recommended.
- Use proper ring end gaps and orientation per Mahle instructions.
