Do I have to replace all of the pistons if I need to replace only one?

Willys Jeep Parts Tech:
You can most certainly replace just 1 piston if that is all that is needed. But its suggested that if the pistons haven't been changed out recently, to replace them as a set.

Is this price per piston?

Willys Jeep Parts Tech:
Yes, these are each.
