Despite losing the match to the South African Club 2-1 Kogalo are through to the Lucrative group stage of the competition on a way goal.
The match ended 2-2 on aggregate having beaten the South African side by a solitary goal in the first leg played in Kenya.
Francis Kahata scored the all important goal that sailed Gor through, just a minute after Harun Shakava had scored an own goal.
Kogalo joins other East African Clubs Al Hilal of Sudan, Rayon Sports of Rwanda and Young Africans of Tanzania who won CAF Confederation Cup playoffs on Wednesday, despite second-leg losses.
CAF club final victories by east African sides have been rare, with the last in 1989 when Al Merrikh of Sudan won the now defunct African Cup Winners Cup.
But the many heartbreaks of the past were forgotten in Khartoum, Nairobi, Kigali and Dar es Salaam as supporters celebrated aggregate victories.
Al Hilal fell 3-1 to Akwa United of Nigeria in Uyo, but squeezed through on away goals.
Rayon had the three-goal lead they built at home to thank for their survival after going down 2-0 to Costa do Sol of Mozambique in Maputo, where the home team missed a penalty.
