What compression height and wrist pin size do these pistons use?

What does the skirt coating do?

• It reduces friction and wear on the piston skirts and cylinder walls, and it lowers operating noise.

How is the wrist pin fit set?

What is the Forged Side Relief design?

• It is a JE forging design with a narrower skirt that reduces friction and power loss, and it allows a shorter wrist pin that saves weight.
