Shaft-Mounted Roller Rockers for Briggs Vanguard 25HP–40HP Mud Motors | Mud Motor Central

MMC has teamed up with the nation’s top performance roller rocker manufacturer to deliver a groundbreaking product. These Shaft Mounted Roller Rockers feature a solid billet bridge across the rocker bosses, enhancing durability and preventing cylinder head damage. Equipped with 5/16 chrome moly push rods, they minimize the risk of bent push rods during demanding field conditions, offering unmatched reliability and performance for serious operators.

For your heads to be compatible you must cut the rocker boss locator tabs flush. A photo showing what needs to be done was added to give a visual example to follow. If you are interested in these rockers and need your heads machined, we offer this service for 150.00. Please contact one our agents to assist you.

Also, you WILL need a spacer under your valve cover to clear the rockers, if you do not have these, we offer them separately
