Fabcraft in Florence,MT also still makes tunnels, trailing arms, skids, and a few other goodies for the ZX chassis. Saw one of their tunnels and skids on an Apex last week up in Cooke City last weedend, looked good, lots of clearance and grating running boards look really good for droping snow out. A guy over in in neighboring ND had 2 or 3 sleds done by them, saw the Rev and the ZX chassis, nice work also.
