Rocker Arms - Forged Aluminum



Erson's Aluminum-Roller Rocker Arms are made from 2014-T6 aircraft quality forgings to guarantee the greatest rigidity and durability in the performance industry. All steel components, including needle bearings are made from aircraft quality, high-alloy steels. A larger roller on the valve tip reduces scrubbing action and improves valvetrain geometry. New larger, specially-designed trunions also improve geometry, decrease the possibility of failure, and help ensure easy installation.
