Description
Building a stroker engine demands pistons engineered to handle increased displacement and cylinder pressure—these S&S forged pistons are purpose-built for the 106″ stroker platform. The 3-7/8″ bore and forged construction deliver the durability required for sustained high-RPM operation, whether you’re running stock or performance cylinder heads. If you’re upgrading to a 4-1/2″ stroke, these pistons are non-negotiable for proper fitment and reliability.
