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.

DRAG CARTEL Lower Timing Chain Guide
 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!

K-SERIES K20 and K24 Performance Heavy Duty Timing Chain
Within the growing K Series Market and extra demand of hi-performance driving even with the standard road engine and/or components such as camshafts that place extra stress on the valve train system, improved chain strength is important. The highly precise side plates reduce friction and improve the revolution fatigue strength by increasing the area of the plates, a reduction in the burrs, and the finish to each individual plate.
