Entering the clash at the Sultan Mohammad IV Stadium leading 2-1 from Saturday's first leg, Kelantan were left stunned as the visitors claimed a two-goal inside the opening 55 minutes, thanks to goals from Mickael-Antoine Curier and Farderin Kadir.
However, Norfarhan Mohammad pulled one back for the Red Warriors in the 72nd minute and the tie looked set to be heading for extra-time, until Lebanon international Mohammed Ghaddar netted in injury-time to send his side through.
Standing in the Kelantan's quest for a domestic treble, after victories in the Super League and FA Cup, are 32-time champions Selangor, who edged Johor FC 2-1 at the Shah Alam Stadium to progress 5-2 on aggregate.
S. Venood opened the scoring for the Red Giants on the half-hour mark when he raced in behind the opposition backline and skipped past Zamir Selamat before netting, although the hosts equalised through Fernando Augusto in the 65th minute to keep alive their slim hopes of making the semis.
Nonetheless, those were duly extinguished seven minutes from time when Fitri Shazwan scored with a delightful left-footed strike to wrap up Selangor's progress.
Big-spending ATM are also through after a 3-1 victory over defending champions Negri Sembilan at the Tuanku Abdul Rahman Stadium saw them progress 6-3 on aggregate.
The hosts got off to a dream start in the fourth minute when Alif Shamsudin scored with a well-placed header, but ex-Negri star Aidil Zafuan came back to haunt his former side when he made it 1-1 just five minutes after.
And from then on, there was only ever going to be one winner, with veteran striker Marlon Alex James netting in 44th and 58th minute to hand his side the win.
ATM will next meet LIONSXII, who overcame a 2-1 first-leg defeat to progress 3-2 on aggregate after a brace from Shahril Ishak handed them a 2-0 win at the Jalan Besar Stadium.
