Looking to build your own X3 chassis? Metalwerx has the answer.   We got rid of the weak single shear mounts and thin walled tubing and designed the strongest chassis base available for your machine.  All bulkheads are constructed from 10 gauge steel with overlays on all bolt locations to make the lightest and strongest suspension mounts possible while all tubing is 1.75" DOM .120" wall for additional strength and rigidity. We then MIG weld everything together in a jig to ensure proper fitment and geometry. The massive 4" boatside gives the perfect amount of extra clearance whether youre building an Ultra4 machine, trail chassis, or rock bouncer.  Our chassis lower includes mounts for a arms, trailing arms, steering rack, front differential, front shocks, carrier bearing, and engine/trans.  As the rear shock mounts are mounted in the upper part of the chassis, we provide you with mesaurements to locate them properly as you finish out the construction.  We can provide you with pickup points for use in CAD/Bendtech as well.  UHMW skid plates are available for this chassis through Factory UTV.   Custom wheelbase, 4130 , and single seat lower options are available upon request, please call for more info.    All chassis lowers have to be shipped freight or picked up at our location in Wheeling, WV.  Freight charges will be invoiced seperately once fabrication has been completed.
