Will you build me a custom set of rockers for my oddball engine?

Actually, virtually every set that goes out the door is a custom set, given the many options for ratios and offsets available. However, we also offer customers full engineering to design and build rocker arms to fit a wide variety of configurations. We cannot say an immediate “Yes” to every request due to the heavy load in engineering, nor can we say, “If its got rocker arms we can build them.” But, given time, we have built rocker arms for some pretty obscure engines, including Ardun, Desoto, Lycoming and Polaris.
