High silicon content pistons (forged from 4032 or MS75) will not stand up to the most extreme stress placed on many racing pistons. If a crack starts to form in a high silicon piston it will continue until the piston experiences a catastrophic failure. Simply stated, adding sand to the aluminum only makes it more brittle. In the rare instance of a 2618-T61 piston cracking, the crack will continue to an area where the stress is not as great and will then stop. Another advantage of 2618-T61 over the high silicon pistons is the ability to keep its shape under extreme pressure and high RPM's. \"Skirt Shrinking\" is not a problem with ROSS Racing Pistons.\u003c\/p\u003e\u003ch2\u003eAvailable options\u003c\/h2\u003e\u003cul\u003e\u003cli\u003ePiston Diameter: +1mm \/ 87mm; +0.5mm \/ 86.5mm\u003c\/li\u003e\u003c\/ul\u003e\u003ch2\u003eEngine build fitment\u003c\/h2\u003e\u003cp\u003eRB30ET (SOHC).
