I have a set of used Mahle 4.030 pistons and a new set of Mahle chrome moly rings. The rings are new. I bought them file fit them and removed them to go another route. Ring gap is .018 on the top ring and .021 on the second ring. The rings were about $150. I'll take $350 OBO for the pistons and rings. The pistons have some of the coating on the skirt rubbed off but doesn't hurt a thing. Pistons are light and balanced perfectly. I have the weights if desired.

 

What stroke and rod length are these for, what's the compression height?
