Product details

The rear axle bearing arrangement is the starting point for this conversion. This Forged Dynalite rear disc brake kit combines black powder-coated 4-piston calipers and 12.19-inch plain-face rotors. Founded in 1977 by Bill Wood and based in Camarillo, California, Wilwood Engineering designs and manufactures disc brake systems for motorsport, street-performance and specialized applications. Its range includes calipers, brake rotors, master cylinders, valves, fittings and brake lines, selected to work together as a complete brake system.

Technical Details

  • Manufacturer part number: 140-5591-B.
  • Rotor dimensions: 12.19 in; 309.63 mm diameter x 0.81 in; 20.57 mm thick.
  • Rotor construction: Iron; vented; Plain Face friction surface.
  • Calipers: 4 pistons; forged aluminum; stainless steel pistons.
  • Caliper attachment: lug mount; 1/8-27 NPT hydraulic inlet.
  • Caliper finish: Black Powder Coat.
  • Rotor/hat wheel-stud clearance patterns: 5 X 4.5 in; 5 X 114.3 mm; 5 X 4.75 in; 5 X 120.65 mm; 5 X 5 in; 5 X 127 mm.
  • Rotor/hat stud-hole clearance diameters: 0.520 in; 13.21 mm. These are hole sizes, not wheel-stud thread specifications.
  • The rotor/hat drilling does not change the vehicle hub or axle wheel bolt pattern.
  • Housing/flange arrangement: Mopar/Dana.
  • Axle flange offset: 2.36 in; 59.94 mm.
  • Wheel-size guide: 15 in; 381 mm minimum nominal diameter; verify actual template clearance.
  • Sold as one kit. Mounting hardware is included. Hubs are not included.
  • Brake pads are included; use the compound and installation instructions specified for this rotor package.
  • Spindles, master cylinder, brake booster and hydraulic brake lines are not included.

Fitment & Compatibility

This kit mounts to Mopar 8-3/4-inch or Dana 60 rear housing ends with a 2.36-inch axle offset and the specified non-adjustable snap-ring axle bearings. Wilwood identifies Green MO400, Strange A1022 and Moser 9400M bearing arrangements in the installation instructions. Identify the housing end and measure the axle offset before ordering; the differential name alone is insufficient.

Use the wheel-clearance drawing in the installation instructions before purchase. The catalog minimum diameter is a guide; barrel shape, spoke clearance and wheel offset still determine fit.

Package and installation requirements

  • No parking brake is included. Wilwood describes this package for applications that do not require a separate parking brake, including custom and competition installations.
