{"product_id":"wilwood-120-16504","title":"Wilwood DynaPro-ST Caliper — Anodized, 1.75\/1.75-Inch Bore, Lug Attachment","description":"\u003cp\u003eWith 4 pistons and 1.75\/1.75-inch bore dimensions, the anodized Wilwood DynaPro-ST brake caliper must be matched to the brake system rather than selected by finish alone. Its 0.81-inch rotor-width specification is separate from rotor diameter. Thermlock pistons distinguish this DynaPro-ST from the stainless-piston DynaPro configurations. It uses the lug-mount arrangement and 7812 pad outline listed below; match rotor centering and hydraulic area before mixing caliper families. Based in Camarillo, California, Wilwood Engineering has its origins in the company Bill Wood founded in 1977. Its designs and manufactured disc brake products cover calipers and rotors alongside master cylinders, valves, fittings and lines. Motorsport, street-performance and specialized installations each require components selected for the complete system.\u003c\/p\u003e\u003ch3\u003eTechnical Details\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eManufacturer part number: 120-16504\u003c\/li\u003e\n\u003cli\u003eComponent: Dynapro Lug Mount-ST; one individual caliper\u003c\/li\u003e\n\u003cli\u003ePlacement: Universal mounting orientation; verify axle position\u003c\/li\u003e\n\u003cli\u003eConstruction and finish: Forged aluminum; Type III Anodize\u003c\/li\u003e\n\u003cli\u003eNominal rotor width: 0.81 inches\u003c\/li\u003e\n\u003cli\u003eRotor width range: 0.75–0.83 inches\u003c\/li\u003e\n\u003cli\u003eRotor diameter range: 10.00–13.06 inches\u003c\/li\u003e\n\u003cli\u003eCaliper weight reference: 4.0 lb\u003c\/li\u003e\n\u003cli\u003ePistons: 4; Thermlock insulated; bore dimensions 1.75\/1.75 inches\u003c\/li\u003e\n\u003cli\u003eHydraulic piston area: 4.80 square inches\u003c\/li\u003e\n\u003cli\u003eDust boots: No\u003c\/li\u003e\n\u003cli\u003eBrake pad shape: 7812; shape number does not specify a friction compound\u003c\/li\u003e\n\u003cli\u003eMounting interface: Lug; mounting centers 5.25 inches\u003c\/li\u003e\n\u003cli\u003eMounting-hole diameter: 0.39 inches\u003c\/li\u003e\n\u003cli\u003eMount height: 2.10 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\u003eVerify the lug mounting interface and the complete rotor-width range shown above.
