Short aluminum gas pedal assembly features a splined shaft supported by dual needle bearings and a knurled aluminum roller foot pedal. The double roller bearing pivot shaft allows smooth acceleration off the corners. The nylon roller foot pedal allows you to feel the throttle without drag and disconnect that is common with round tube or flat steel pedals. The pedal and linkage arm can also be adjusted from side to side for precise alignment to your chassis. The short throttle shaft support is 3-1/8″. NOTE: A solid throttle stop mounted under the pedal should be used with this throttle.
