The tappet covers on the Milwaukee Eight^® engine have grown substantially in height compared to Twin Cam engines. This additional height not only makes it challenging to adjust pushrods, but the covers have lost a bit of styling in their redesign. Make way for the new JIMS^® billet “low profile” Milwaukee Eight tappet covers. Not only do the JIMS tappet covers have a sleek new look, but they are approximately 1/2″ lower then stock – making pushrod adjustment easy to do. Made from 6061 billet aluminum, these covers have JIMS “DNA” embedded in their design & work with stock and aftermarket alignment guides. To achieve this height difference, the covers were designed to be installed with Twin Cam pushrod covers, they will NOT work with standard Milwaukee Eight pushrod covers. JIMS also offers these tappet covers with JIMS billet pushrod covers for the ultimate valve train cover upgrade for your Milwaukee Eight engine.
