Your flight will generally(*) land as if it was a "domestic" flight, and you will be let out into the standard terminal 4 departures area. From there you will be able to catch the Delta Shuttle to terminal 2 if required. You will NOT need to re-clear security.
(*) Generally, because occasionally pre-cleared flights will still be forced to go through some level of immigration or customs control on arrival in the US. This is rare, but can happen. In this case you would need to re-clear security in either T4 or catch the airtrain to T2 and re-clear security there.
