# Super Junior-83z Extends Group’s 20th Anniversary Momentum with Leeteuk and Heechul’s First Unit Album

Super Junior members Leeteuk and Heechul are set to debut their new unit, Super Junior-83z, with a first mini album. Built around the pair’s shared birth year of 1983, the project expands the narrative of the veteran group as it continues celebrating its 20th anniversary.

Leeteuk and Heechul will release the debut mini album Promise under the new unit Super Junior-83z. According to official announcements, the album will be released on major music streaming platforms at 6 p.m. KST on July 13 and will also be available in physical format. The unit name reflects the fact that both artists were born in 1983.

More than a one-off collaboration, the project represents another chapter in Super Junior’s long history of unit activities. Over the years, the group has broadened its musical identity through various sub-units, and this time its longtime leader Leeteuk joins forces with Heechul, whose distinctive personality has made him one of the group's most recognizable members.

Having spent two decades together as teammates, the two artists are expected to showcase their chemistry from a fresh perspective through this release. Their longstanding friendship and experience have heightened anticipation among fans for the unit’s musical direction and on-stage dynamic.

The album, titled Promise, also carries symbolic weight as Super Junior continues commemorating its 20th anniversary. Rather than simply introducing another unit, the release highlights how the group continues to reinvent itself while building on the legacy it has established over the past two decades.

Industry observers expect the project to resonate with longtime fans while also offering newer audiences another entry point into Super Junior’s extensive catalog. Further details, including the track list and promotional schedule, are expected to be unveiled ahead of the album’s release.
