The included 0.927-inch pins are also well-built for the forces they'll endure.

This set includes eight pistons, enough for a full V8 engine. Please note that these pistons are not CARB approved and cannot be shipped to California. It's always a good idea to consult your engine builder or refer to Mahle's installation instructions for specific details regarding assembly and break-in procedures to ensure optimal performance and longevity.
