Edelbrock .057 x .049 metering rod pair is a direct-replacement rod set that controls fuel flow in AVS-style carburetors. Its specific taper and orifice size help tune midrange and part-throttle fueling during rebuilds or when changing jetting to refine drivability. Sold as a matched pair, these rods are intended for Edelbrock Thunder Series AVS carburetors only.
