Wilwood Red Dynalite Parking Kit for 2.36-inch New-Style Ford — Rear Drilled/Slotted Rotors, 12.19-inch

Red SRP brakes share the compact parking-brake mechanism within these Ford drum/rotors. At the rear axle, this kit pairs red powder-coated 4-piston calipers and 12.19-inch SRP drilled-and-slotted rotors with the mounting hardware for Big Ford New Style, 2.36-inch offset. Based in Camarillo, California, Wilwood Engineering was founded by Bill Wood in 1977. It designs and manufactures disc brake systems for motorsport, street-performance and specialized applications, with a range including calipers, rotors, master cylinders, valves, fittings and brake lines. Selecting the mounting and hydraulic components together is part of building the complete brake system.

Technical Details

• Manufacturer part number: 140-7582-DR.
• Rotor dimensions: 12.19 in; 309.63 mm diameter x 0.81 in; 20.57 mm thick.
• Rotor construction: Iron; vented; SRP Drilled & Slotted friction surface.
• Housing/flange arrangement: Big Ford New Style.
• Axle flange offset: 2.36 in; 59.94 mm.
• Wheel-size guide: 15 in; 381 mm minimum nominal diameter; verify actual template clearance.
• Calipers: 4 pistons; forged aluminum; stainless steel pistons.
• Caliper attachment: lug mount; 1/8-27 NPT hydraulic inlet.
• Caliper finish: Red 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: 0.52 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.
• 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.

Package and installation requirements

• Mechanical parking is provided by shoes within the rotor’s integral drum. The 12.19-inch disc surfaces are operated by the service calipers, so cable adjustment does not replace hydraulic brake setup.
• This kit supplies no parking cable or flexline set. Wilwood identifies universal cable kit 330-9371; confirm the required routing and any installation modifications.

Fitment & Compatibility

Although this package uses the Big Ford new-style/Torino flange, its required axle offset is 2.36 inches. That dimension differentiates it from the commonly encountered 2.50-inch version with a similar housing-end description. Check the actual shaft and housing combination against DS498 and the offset worksheet rather than inferring the offset from the flange name. The 1990 Lincoln Town Car row below does not override those measurements. The one-piece drum/rotor houses an internal parking-brake shoe assembly, while the four-piston caliper operates the service brake. Before fitting the system, establish how the parking cables will attach and release, select the hydraulic lines, and check the complete wheel profile. The nominal 15-inch wheel guide is not a promise that every 15-inch wheel clears.

The listed applications below retain their equipment qualifiers. Check the matching row and each referenced note before selecting the kit.
