Fitment & Compatibility

DS-1183 specifies the Magnum Force drop spindle and included aluminum wheel hubs. Match the exact spindle, bearing fit and selected 5 x 4.50 or 5 x 4.75-inch wheel pattern; no universal vehicle or ABS compatibility is implied. The specified studs use a 1/2-20 thread; the hat's 0.520-inch mounting holes are a separate dimension. Hydraulic hoses are separate and the 18-inch wheel guidance requires a template check.
