K-Series Modified Crank Timing Gear
Factory K-Series Timing Chain Gears on higher HP turbocharged or all-motor applications have a higher risk of the timing chain gear to break its positioning dowel pin causing your engine to lose timing and potentially do major damage to the engine in this occurrence.
The Modified Crank Timing gear solves this problem by modifying the factory gear to be locked in place using a crank key-way.

 Prevents timing chain slippage off the crank pulley chain gear when performing a cam swap. If you're a K-Series head, you know about the keeping the timing chain held up when performing a cam swap and how much of a pain it is when it does slip!

Fits both K20 and K24 engines
