A lightweight billet aluminum version of the OEM power steering pulley, sized to allow a 10% reduction in power steering pump rotational speed. This will lessen the parasitic losses from the power steering pump at higher rpms by preventing pump over-rotation. Please note this pulley is non-ribbed which allows us to achieve the under-drive feature. Similar to the water pump pulley, ribs are not needed on the power steering pulley. This pulley has been proven by countless hours of track abuse with no problems whatsoever. Fits all of the 24V VR6 engines.
