{"product_id":"wilwood-120-11332","title":"Wilwood FSLI4-ST Left Four-Piston Caliper, Thermlock \/ 1.88\/1.75-Inch Bores \/ 1.25-inch Rotor Width","description":"\u003cp\u003eThe left FSLI4-ST uses Thermlock pistons in a differential four-piston forged housing. A nominal 1.25-inch rotor-width channel and 1.88\/1.75-inch bore combination define this 5.18-square-inch configuration. For motorsport, street-performance and specialized braking applications, Wilwood Engineering designs and manufactures calipers, brake rotors, master cylinders, valves, fittings and brake lines. The disc brake company was founded by Bill Wood in 1977 and is based in Camarillo, California.\u003c\/p\u003e\u003ch3\u003eTechnical Details\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eManufacturer part number: 120-11332. Component: Forged Superlite Internal 4 ST caliper.\u003c\/li\u003e\n\u003cli\u003eSupply: one brake caliper, not a complete axle brake kit. Match the mating rotor, pads, bracket and connection hardware to the installation.\u003c\/li\u003e\n\u003cli\u003eBore configuration 1.88\/1.75 inches across 4 pistons; piston material: Thermlock. Hydraulic effective area: 5.18 square inches.\u003c\/li\u003e\n\u003cli\u003eConstruction and surface: forged aluminum housing finished in Type III anodize.\u003c\/li\u003e\n\u003cli\u003eBracket interface: 3.50-inch lug centers with 0.45-inch holes. Specified mount height: 2.85 inches; orientation: left hand.\u003c\/li\u003e\n\u003cli\u003eCaliper weight: approximately 5.2 lb.\u003c\/li\u003e\n\u003cli\u003eNominal rotor width 1.25 inch; compatible outside diameter from 11.75 through 13.06 inches. Specified rotor-width limits: 1.19–1.38 inch.\u003c\/li\u003e\n\u003cli\u003ePiston dust boots: not fitted.\u003c\/li\u003e\n\u003cli\u003ePad fit is type 7420. Match the pad dimensions and compound to the rotor and intended braking conditions.\u003c\/li\u003e\n\u003cli\u003eHydraulic inlet thread: 1\/8-27 NPT. Use a fitting with the correct thread and sealing seat.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment \u0026amp; Compatibility\u003c\/h3\u003e\u003cp\u003eCheck the left-hand body against the bracket and rotor before fitting. The ST piston construction should be identified explicitly when replacing a standard FSLI4 that shares its external mounting format.\u003c\/p\u003e\u003cp\u003ePMB Performance has worked with brake components for over 20 years. Share the required piston sizing, rotor measurements and bracket drawing for help checking the match.\u003c\/p\u003e","brand":"Wilwood","offers":[{"title":"Default Title","offer_id":67764006191282,"sku":"120-11332","price":457.6,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0521\/8792\/2610\/files\/Forged_Superlite_Internal_4_ST-xl_e0df38c4-a654-421e-9112-d66e8bad4e98.jpg?v=1792508569","url":"https:\/\/pmbperformance.com\/products\/wilwood-120-11332","provider":"PMB Performance","version":"1.0","type":"link"}
