1 Individual 426 Street hemi Intake rocker arm shaft
At Manton, ensuring valve train stability is our top priority. We manufacture each shaft with robustness in mind, utilizing .250 wall thickness 4130 Chromoly steel. These heat-treated shafts undergo precise machining in a four-axis milling center, followed by centerless grinding to achieve optimal sizing and hard chrome plating for enhanced wear resistance. This meticulous process guarantees reliability, whether on the street or under high-performance conditions. Each shaft features threaded plugs at both ends to prevent oil leaks, offering superior sealing compared to O-rings. With two exhaust shafts required per engine, our American-made product is designed to meet the demands of your 426 Street Hemi.
