This version requires non-adjustable snap-ring Green bearings: Mopar MO400, Strange A1022 or Moser 9400M. The RP400 bearing with a pressed-on five-hole retainer is not compatible. Verify bearing diameter, flange pattern, axle register and shock clearance against DS-532; relocation of shocks may be necessary. The maximum axle flange is 6.61 inches with the specified chamfer. Hydraulic hoses, fittings and parking cables are separate; the universal 330-9371 cable kit requires application-specific installation. Nominal minimum wheel diameter: 17 in; 431.8 mm. Compare the actual wheel barrel and spokes with the linked clearance drawing; diameter alone does not establish fit.\u003c\/p\u003e\u003ch3\u003eInstallation documents\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/www.wilwood.com\/PDF\/DataSheets\/ds532.pdf\"\u003eInstallation instructions\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/www.wilwood.com\/Images\/BrakeKits\/Axle-Offset-Worksheet-Wilwood.pdf\"\u003eTechnical bulletin\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eWARNING: This product can expose you to chemicals including Arsenic, Cadmium, Chromium (Hexavalent compounds), Lead, Nickel, Cobalt and Antimony Trioxide which are known to the State of California to cause cancer or other reproductive harm.
