20th Century Heisei: Turboranger, Fiveman, Jetman, Zyuranger, Dairanger, Kakuranger, Ohranger, Carranger, Megaranger, Gingaman, GoGoV.
21st Century Heisei: Timeranger, Gaoranger, Hurricaneger, Abaranger, Dekaranger, Magiranger, Boukenger, Gekiranger, Go-Onger, Shinkenger, Goseiger, Gokaiger, Go-Busters.
Same thing can be done with Ultraman, Metal Heroes, and Godzilla, but I don't feel like typing that all out.

Metal Heroes isn't usually cut up into Showa/Heisei, though. Probably because the franchise was so random that you can't really define it by era. If anything, it's usually categorized by show themes: the Space Sheriff trilogy, the Rescue Hero trilogy, the B-Fighter shows, and the rest that just kind of fill in gaps between those.

Officially, though, they are classified as Showa. In this case I think it's less about when they were released and more about the tone and aesthetic of the films. Shin is an oddball, but ZO and J are very much Showa Riders in design and story. The stuff from Kuuga onwards is very much a different franchise in a lot of ways (serialized storylines, multiple heroes on each show, an abandonment of the reconstructed human/evil organization tropes, etc.).
