{"product_id":"wilwood-140-7146-dr","title":"Wilwood Ford 8.8 Red Dynalite Parking-Brake Kit — Rear 12.19-inch Drilled\/Slotted Rotors, Five-Lug Axles","description":"\u003cp\u003eA red-caliper and SRP-disc combination completes the specified Ford 8.8 rear mounting arrangement. 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 Ford 8.8 five-lug, 2.50-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.\u003c\/p\u003e\u003ch3\u003eTechnical Details\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eManufacturer part number: 140-7146-DR.\u003c\/li\u003e\n\u003cli\u003eRotor dimensions: 12.19 in; 309.63 mm diameter x 0.81 in; 20.57 mm thick.\u003c\/li\u003e\n\u003cli\u003eRotor construction: Iron; vented; SRP Drilled \u0026amp; Slotted friction surface.\u003c\/li\u003e\n\u003cli\u003eHousing\/flange arrangement: 8.8 Ford.\u003c\/li\u003e\n\u003cli\u003eAxle flange offset: 2.50 in; 63.5 mm.\u003c\/li\u003e\n\u003cli\u003eWheel-size guide: 15 in; 381 mm minimum nominal diameter; verify actual template clearance.\u003c\/li\u003e\n\u003cli\u003eCalipers: 4 pistons; forged aluminum; stainless steel pistons.\u003c\/li\u003e\n\u003cli\u003eCaliper attachment: lug mount; 1\/8-27 NPT hydraulic inlet.\u003c\/li\u003e\n\u003cli\u003eCaliper finish: Red Powder Coat.\u003c\/li\u003e\n\u003cli\u003eRotor\/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.\u003c\/li\u003e\n\u003cli\u003eRotor\/hat stud-hole clearance diameters: 0.52 in; 13.21 mm.

A four-lug axle or an assembly with different shafts and offset must not be assumed compatible. Use DS426 together with the axle worksheet to identify what is actually installed. The kit combines four-piston service braking with internal shoes in the parking-brake drums; the hydraulic calipers do not perform the mechanical parking function. Provide the housing and axle measurements when requesting assistance; the installed hardware determines compatibility. Check wheel bolt-circle compatibility, parking-cable attachment and the flexline route before assembly. Each of those checks matters independently of the Ford 8.8 differential designation.\u003c\/p\u003e\u003cp\u003eWheel selection requires the complete clearance profile in the instructions. Confirm radial and spoke clearance; do not rely on the minimum diameter alone.\u003c\/p\u003e\u003ch3\u003eManufacturer references\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/www.wilwood.com\/Search\/PartNoSearch?q=140-7146-DR\"\u003eWilwood product and configuration information\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/www.wilwood.com\/PDF\/DataSheets\/ds426.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\u003ePMB Performance has more than 20 years of experience helping customers select brake components.
