Thanks to their design in duralumin (an alloy made from aluminium, copper, magnesium and manganese) with a blue anodised finish, these pulleys are as light as they are strong, significantly reducing the inertia momentum of the engine's axis of rotation. Power losses are minimised and throttle response is improved. Please note that this kit does away with the original air pump. Kit contents : Water pump pulley Alternator pulley Belt
