These custom pistons are available in +0.040" ( 3.72" ) bore with a compression height of 1.17"
Ross Racing Pistons are made from 2816 forged alloy, which is a much stronger and durable material than most of the other shelf stock pistons on the market which are made from 4032 material.
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.
