COMP Cams hydraulic flat lifters for AMC 199–258 six-cylinder applications feature a patented orifice metering valve and lightweight check valve disc to meter oil to the rocker arms and improve response. The design maintains continuous contact at the pushrod seat to avoid excessive oiling at high rpm, while longer pistons and heat-treated pushrod seats increase load-bearing surface and resistance to wear in the stated AMC/Jeep engines.
