SUPER JUNIOR-83z Ultimate Guide: Leeteuk & Heechul's New Unit

Who Are SUPER JUNIOR-83z?

SUPER JUNIOR-83z is the newest unit from Super Junior, pairing Leeteuk and Kim Heechul — and the name is the story: both were born in 1983, making this the ‘83-liners’ unit. Announced at midnight on July 1 and debuted on July 13, 2026 at 6 PM KST with the mini album 너를 위한 약속 (Promise), it’s a unit two decades of E.L.F. (Super Junior’s fandom) have been waiting for.

The response was immediate: within a day, Promise hit No. 1 on iTunes Top Albums charts in 10 regions — including Hong Kong, Indonesia, Taiwan, Thailand, Singapore, the Philippines, Vietnam, Malaysia, Macau, and Paraguay.

The Album: Promise Track by Track

Six tracks that split the difference between “unit” and “two soloists”:

“너를 위한 약속 (Promise)” — the title: a bright, 1990s–2000s band-sound track. The MV is a mini-drama built around a fictional “Bus 83” — friendship as a route you keep riding
“SOLOVE” — unit track
“온새미로 (ONSAEMIRO)” — unit track
“More Than Love” — unit track
“Bad Name” — Leeteuk solo
“GODOGNAM” — Heechul solo

Their debut music show stage was set for July 18 on MBC’s Show! Music Core.

The Unit Tradition They’re Joining

Super Junior practically invented the K-pop sub-unit playbook (what’s a sub-unit?):

SUPER JUNIOR-K.R.Y. (2006) — widely considered K-pop’s first official sub-unit
SUPER JUNIOR-T (2007), -M (2008), -Happy (2008)
SUPER JUNIOR-D&E (Donghae & Eunhyuk, 2011)
SUPER JUNIOR-L.S.S. (Leeteuk, Shindong, Siwon — 2023 Japan, 2024 Korea)
SUPER JUNIOR-83z (2026) — the latest chapter

Two members debuting a new unit in their 21st year as a group is rare air in K-pop — and part of why the debut made headlines beyond the fandom.
