Adapting your UI to work with C.H.A.S.E.R

By default, most user interfaces scripts, should work with C.H.A.S.E.R, how ever a slight modification is necessary. Most of the speedometers, will read the current gear from the GetVehicleCurrentGear() native

How ever, C.H.A.S.E.R does not utilize GTA default gearbox, and instead simulate it's own, where the current gear can be accessed by simply using a statebag. You can learn more about the statebag here:
