This is the spring in the Brush Assembly that goes between the Brush Cap and the Spring Cap. This part may also be purchased in the KitchenAid Brush Holder/Cap Kit if the other parts of the kit are needed.
Note: This original KitchenAid mixer spring will ONLY fit the K45SS, K5SS and later models. This spring is not interchangeable with the older style, or Pre-SS, mixers that originally had the brass fittings. This part WP116287 will replace obsolete numbers 116287 and 4161746.
