What is the advantage of the adjustable timing keyways on the crankshaft sprocket?

The three keyways on the crankshaft sprocket allow you to fine-tune your engine's timing by -4, 0, or +4 degrees. This adjustability is useful for optimizing engine performance based on your specific build and driving needs.

What is the purpose of the Torrington thrust bearing or brass wear shim?

The Torrington thrust bearing or brass wear shim is integrated into the camshaft sprocket. Its function is to reduce friction and wear between the sprocket and the camshaft, ensuring smoother operation and longer component life.

Does this kit include everything needed to replace the timing chain?
