ASC539521 Pistons 9.5-1
These Aluminum Pistons are Flawless and Balanced within 1 gram. Their Quality Control is amazing. They broke in very easily and oil consumption is ultra low, the performance is excellent and they run very cool and smooth. The communication was comforting and I’m extremely satisfied with the product.
