Hydraulic Roller cams offer the sizeable power and torque increases that are available only with roller cams, plus the low maintenance convenience of a hydraulic cam. Hydraulic Roller cams are available for retrofit (converting earlier non-hydraulic roller cam engines), and to increase power output of engines already equipped with hydraulic roller cams. Produced using steel billet cam cores, carburized or induction-hardened for strength and wear resistance.
