Because all roller cam lobes are ground flat instead of tapered, like hydraulic or solid cams, COMP Cams provides a means of holding the cam back to the rear of the engine. Their cam buttons ride between the front of the timing gear and the back of the front cover and can be shimmed for proper endplay of the cam. COMP Cams makes solid nylon buttons and roller bearing thrust buttons for the ultimate in performance.

Professional engine builders are familiar with camshaft walk. Excessive camshaft end play can produce erratic spark timing and the movement of the timing chain/gear can destroy the timing cover. Moroso has solved this problem with a wear resistant cam stop button that mounts in an aluminum holder, which bolts to the cam gear by way of a retaining plate. These button assemblies do not allow the cam to walk forward, stabilizing ignition timing and preventing costly engine damage.
