Ross Racing Pistons:

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.

Note: We recommend Joe Gibbs Break in Oil for all new engines.
