Pistons come with NPR Gas Nitrided top ring, three pcs. 0.225 wall Carbon steel (upgrade to H13 available). All of Ross Racing Pistons (since 1985) have been forged from 2618 billet bar stock and have been heat treated and aged to a T61 condition (2618-T61). 2618-T61 is the material that is used when fatigue resistance and durability are of prime importance by all premium racing piston manufacturers. This material has less than 1% silicon particulate content. 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. ARP 2000 fasteners (L19 fasteners are available as an upgrade). High tensile 4340 forged steel.
Dowelled caps for precision alignment. Weight Matched Sets +/- 1 gram.
Vacuum degassed to remove impurities. Product images are for description purposes only. Note: We recommend Joe Gibbs Break in Oil for all new engines.
