Product details

A fixed-bearing Special housing end separates this kit from an ordinary C-clip Chevrolet rear axle. 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: 140-5746-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: 12 Bolt Special.
  • Axle offset: confirm with Wilwood; the current product page specifies 2.91 inches and the installation cover specifies 2.81 inches.
  • 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

Use this package only with the Chevrolet 12-bolt Special housing-end arrangement and its 3.15-inch fixed axle bearing. The listed modified GM applications still require that rear axle hardware; a vehicle name or front spindle conversion does not establish rear-kit fit. Wilwood currently lists a 2.91-inch axle offset, while the DS293 instruction cover specifies 2.81 inches. Measure your axle and have Wilwood confirm the correct kit before ordering.

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.

The application table below identifies the model-year and factory-equipment combinations. Match the entire row, including its numbered notes.

Package and installation requirements

  • No parking-brake mechanism is supplied. Confirm that this arrangement meets the requirements of the vehicle and its intended use.
  • Axle offset requires confirmation: current product page 2.91 inches; DS293 instruction cover 2.81 inches.
