What is a rotating assembly? 

Rotating assemblies are typically key or pin-driven. The stationary assembly consists of a retainer, where the ring is held in place and can be turned by either an axial force (pin) through its spiral groove on a shaft sleeve as well as being clamped down.

What are stroker kits?

A stroker kit is a great way to increase your engine's displacement by lengthening the stroke of the piston.
