Our pistons are custom made by Wiseco and CP Pistons. Our package is designed using a 5.765" rod, the longest length possible (Crower Maxi-Lights in stock) . ARCA style pistons fit these aluminum and stock type iron heads. Ultralight strutted pistons are also in stock. Most use thinner metric rings.
Tech note: .860" is the shortest compression height we can safely build. This fits several of our rod/stroke combinations.
