In high boost and abusive applications such as Rally and Drag Racing, Ross designed a stronger piston forging with rigid, high strength 52100 bearing steel wrist pins to minimize flex and pin distortion.  The forged side relief design allows for the ultimate balance of strength and weight.  The inverted dome recess promotes combustion chamber efficiency and OEM style lock retention clips provide ease in installation.
