These are the same pistons we use in our winning race and high performance S54 stroker builds for customers around the world.
Afer many years of working closely with CP, these pistons continue to meet the highest level of expectation: Winning. The finest available; others agree- you can find these same pistons in most of the worlds most powerful N/A and Turbo builds. For extremely high stress applications, such as forced induction, or high-revving strokers. We recommend checking the Heavy Duty Pin option.

Custom bore of 87.2mm is also available, other C/R are as well, these orders carry a small custom fee (+$50)
