SWorkz S350 & MBX7 steel skid plate
New from SWorkz and made to fit the S350 EvoII, FCSS chassis converted standard S350’s as well as Mugen’s MBX7 is a stainless steel skid plate. The plate protects the rear end of the chassis on abrasive surfaces from excessive wear while the slightly wider design keeps harm away from the rear suspension hanger. Countersunk holes allow for precise positioning of the plate on new or nearly new chassis plates.
