Ford Ecoboost 2.0 Keyed Crank and Gears

from $87.17

MASSIVE SPEED CRANKSHAFTS AND DRIVE GEARS

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 we're 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!!!

 

Cranks: 

We started with  NEW (high quality professionally remanufactured in the case of the 2.3 Ranger and 2.5 Dura - new from ford no longer available ) OEM crankshafts and added 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. This will prevent COSTLY damage to your engine! Use with our keyed chain drive pulley.

 

Gears: 

 

We started with A brand new Ford ? Mazda chain drive gear and EDM cut a proper keyway to allow the timing chain drive gear to be positively locked to the crank in the event the crank pulley bolt should come loose. This will prevent COSTLY damage to your engine! Use with our keyed crankshaft. Includes key.

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. 


Keyed gears and cranks are sold seperately

Modified IN HOUSE at Massive Speed's headquarters right here in the USA!!!
