At the end of each City Kings fight, the winning gang receives an ultimate box containing one ultimate part and gains control of one City District. To capture the entire city, the gang needs to conquer 10 districts. If successful, all gang members will be rewarded with an ultimate toolbox - a temporary upgrade for the car that improves either its health or damage power.

PLEASE NOTE: unlike regular toolboxes, ultimate toolboxes have a TEMPORARY effect. There’s a timer next to it that shows how much time is left before toolbox loses its effect.
