Will the Super Pro frame kit swingarm fit my stock frame?
No, the Super Pro frame uses an entirely different upper shock mount. In addition, the shock is not the same as other CRF/XR50 shocks. We have a custom wound spring that handles that super high leverage ratio of the rear suspension. We only sell this frame as a set that includes the frame, subframe, shock, and swingarm ($1899.95). You will need your stock CRF/XR50 swingarm bolt, axle bolt, and chain adjusters (plus all the other parts).
