Fitment & Compatibility
Match DS-126, which identifies the press-on five-hole flange bearing as Mopar RP400. Do not substitute the separate snap-ring-bearing kit solely because its nominal offset is also 2.36 inches. Verify housing-end dimensions, axle offset, wheel drilling and flexible-line routing.
