When installing these pistons, it's important to ensure your cylinder walls are properly honed to match the piston skirt design and that you follow the manufacturer's recommended ring gap specifications. Proper assembly and tuning are critical to achieving the performance and reliability these pistons are capable of. Remember, this set is not CARB approved and cannot be shipped to California.
