Keyed Cam Timing Chain Drive Gear Pulley Sprocket compatible with Ford Ecoboost 2.0L 2.3L 2015 2016 Mustang Turbo RS Focus ST also for Lincoln MKC

One fatal flaw of the Duratec / MZR line since day one has been the complete lack of keys/dowels/locating devices on all of the cam timing components. While I'm sure eliminating them made it far easier for robots to assemble the motors in production (and scared away shade tree mechanics from working on them), the possibility of slippage ensured disastrous results. The potential for slippage, while remote on a stone-stock-untouched-grocery-getter, was much more a threat on the modified, high RPM motors us folks like to build. Massive has stepped in and now offers a complete line up of keyed crank shafts and companion timing chain drive gears!!!

• We started with A brand new OEM chain drive gear. EDM cut a proper key way to allow the timing chain drive gear to be positively locked to the crank in the event the crank pulley bolt should come loose.
• Prevents COSTLY damage to your engine!
• Includes key. Use with our keyed crank.
• We've always felt the cam gears don't need a key way or dowel. Allowing them to orbit whilst installing the timing chain is a must. Additionally, there is far less chance for slippage, reuse the now unnecessary diamond washers from the crank pulley on them if you please, run some loc-tite as well.
• Made in house right here in the USA!
