This is an amazingly made crank pulley with a toothed ring for a crank position sensor. This kit comes with the dynamic damper ring, pulley, pulley lock plate, heavy duty damper bolt and washer, and the fittings.  It comes preassembled and balanced. 
Torque the bolt to 70LB.FT. and a touch of blue locktite. This also comes with fitting instructions. Here's some fitting tips by the manufacturer...
 
Fitment tips
To ensure the pulley is a snug fit on all engines, in some cases light honing of the centre bore may be required. If fitment is too tight, check for burrs on the end of the crankshaft tail and also the key.
Check that the large crank bolt does not bottom-out in your crankshaft thread before fitting the pulley. On rare occasions, the thread may not be fully tapped and the longer bolt may bottom out before the pulley is tight.
Apply a small amount of medium strength thread lock to the large crank bolt and torque to 70lb.ft
Now mark the position of the damper to the pulley before removing the four cap head screws, to maintain the balance.
The lock plate installs over the central bolt, and is fixed in place by the four cap head screws. Apply a small dab of thread lock and re-torque to 18lb.ft
For ignition timing setup, turn the engine to TDC and mark across from the timing bracket (if fitted) to the damper with a paint pen or scribe. This position will vary from one timing cover to another.
For engine management, check where the missing 36:1 tooth needs to sit in relation to the position sensor when the engine is at TDC. Mark the tooth, remove the pulley from the damper, noting the position to maintain balance, and remove the chosen tooth. This should not significantly affect the balance.
