Manley 62-01 Ford Boss 351C-M 1.73in x 7/16in Aluminum Roller Rocker Arm Kit

Manley Performance is well-known for making strong internal engine components, and this roller rocker arm kit for the Ford Boss 351C-M engine is a great example. These aren't just standard rocker arms; they're designed to help your engine breathe better and perform more reliably, especially if you're pushing the limits or rebuilding your top end. The roller tip design reduces friction compared to traditional stamped steel rockers, which means less wear and tear on your valve train and a bit more power making it to the wheels.

Crafted from aluminum, these rocker arms are lighter than their steel counterparts, reducing the overall mass the valvetrain has to move. This can lead to improved engine response and durability under stress. The 1.73-inch ratio is a common choice for these engines, offering a good balance for street and mild performance applications. They use a 7/16-inch stud size, which is standard for many Ford V8 applications of this era. When installing, ensure you're using the correct valve springs and pushrods to match the rocker arm ratio and lift for optimal performance and longevity.
