The 16" wide center case is CNC laser cut, formed, robot welded and has a CNC machined center out of .188 4130 chrome moly steel. Housing fill sleeve and drain plug boss are factory welded in the center case.

The center case has internal axle tube gussets for added rigidity and axle tube stability. Axle tubes are made of 3-1/2x.250" 4130 tubing. The 3/8-24" 12-point 3rd member studs thread into the housing face from the inside. This weld-up kit will make a housing 61" wide with 1" of pinion offset to the passenger side.
