movable rear bearing hangers

[foreverfaster]

Who makes the chassis that has the rear bearing hangers on,.. what looks like a slide rail that pins in place.. appears you can change the overall wheel base of the kart a couple inches if needed.

George Barks GeForce has adjustable wheel base like that, think it’s nut and bolted though has like 8 sets of holes
