Engine – Rocker Arms & Camshafts

It is highly recommended that you change the rocker arms with every cam change and keep them together as a package or kit. The reason is this, the rockers burnish themselves to each cam lobe. As we know each cam is ground on a different angle. Each rocker wears at a different angle. If you use rockers from one camshaft on another, they will most likely wear a trough in the new camshaft lobes. We also cannot warranty any cam sold from LC Engineering unless the rocker arms have been replaced with new ones. Call our technicians for details.
