ROLLMASTER VERNIER ADJUSTABLE TIMING GEAR TO SUIT FORD FAIRLANE NA NC NF NL SOHC MPFI 3.9L 4.0L I6

This Rollmaster billet steel cam gear is produced in two parts which allows the outer sprocket section to move separately and independently to the inner hub by way of elongated slots. Infinite adjustment to cam timing is possible by positioning the camshaft to the required angle then locking the socket head screws around the perimeter of the gear which clamps the entire unit together as one solid cam sprocket.The cam gear teeth are all nitrided for increased durability and peace of mind in even the harshest environments. In addition, the 5-bolt design eliminates any chance of slippage.

Installation of this double row vernier gear is a breeze as it can be installed using simple hand tools in just the same manner as any other timing set. The real difference being, the cam can be advanced or retarded to maximise engine performance. Even stock engines can benefit by dialling-in cam timing.
