{"product_id":"wilwood-120-16970","title":"Wilwood AeroDM Brake Caliper — Front Left, Anodized, 5.04-Inch Lug Mount for Toyota 4Runner (2015–2021)","description":"\u003cp\u003eThe 5.04-inch lug attachment distinguishes this front left Wilwood AeroDM brake caliper for Toyota 4Runner. This individual anodized unit is built for the 1.25-inch-wide rotor configuration and requires accurate alignment with the mating rotor and bracket. Calipers, brake rotors, master cylinders, valves, fittings and brake lines are among the disc brake components designed and manufactured by Wilwood Engineering. Bill Wood founded the company in 1977; it is based in Camarillo, California. The range serves motorsport, street-performance and specialized systems, with component selection determined by the full brake arrangement. AeroDM is a forged six-piston caliper using a vehicle-specific direct lug mount. It is intended for the matching Wilwood rotor and conversion geometry, rather than the stock rotor by itself. Verify the package, side and lug offset before ordering a replacement.\u003c\/p\u003e\u003ch3\u003eTechnical Details\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eManufacturer part number: 120-16970\u003c\/li\u003e\n\u003cli\u003eComponent: AeroDM Lug Mount; one individual caliper\u003c\/li\u003e\n\u003cli\u003ePlacement: Front Left\u003c\/li\u003e\n\u003cli\u003eConstruction and finish: Forged aluminum; Type III Anodize\u003c\/li\u003e\n\u003cli\u003eNominal rotor width: 1.25 inches\u003c\/li\u003e\n\u003cli\u003eRotor width range: 1.10–1.28 inches\u003c\/li\u003e\n\u003cli\u003eRotor diameter range: 12.19–13.38 inches\u003c\/li\u003e\n\u003cli\u003eCaliper weight reference: 8.9 lb\u003c\/li\u003e\n\u003cli\u003ePistons: 6; stainless steel; bore dimensions 1.75\/1.50\/1.50 inches\u003c\/li\u003e\n\u003cli\u003eHydraulic piston area: 5.94 square inches\u003c\/li\u003e\n\u003cli\u003eDust boots: No\u003c\/li\u003e\n\u003cli\u003eBrake pad shape: 6617; shape number does not specify a friction compound\u003c\/li\u003e\n\u003cli\u003eMounting interface: Lug; mounting centers 5.04 inches\u003c\/li\u003e\n\u003cli\u003eMounting-hole diameter: 0.59 inches\u003c\/li\u003e\n\u003cli\u003eHydraulic inlet thread: 1\/8-27 NPT\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment \u0026amp; Compatibility\u003c\/h3\u003e\u003cp\u003eReplacement caliper for the Wilwood AeroDM front conversion on Toyota 4Runner (2015–2021).
