Differential piston bores compensate for leading-edge mechanical loading and temperature variances across the pad face to reduce pad taper wear in sustained high temperature applications. Thermlock® pistons in the ST models block heat transfer from the pads and reduce temperatures in the caliper, fluid, and seals by up to 25% over standard stainless steel pistons. These are the go-to calipers for all types sustained hard braking on dirt and asphalt ovals and a wide range of off-road, rally and road course applications.\u003c\/p\u003e\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cdl\u003e\n\u003cdt\u003eManufacturer part number\u003c\/dt\u003e\n\u003cdd\u003e120-11329\u003c\/dd\u003e\n\u003cdt\u003eUPC\u003c\/dt\u003e\n\u003cdd\u003e889545001365\u003c\/dd\u003e\n\u003cdt\u003eShipping weight \u0026amp; size\u003c\/dt\u003e\n\u003cdd\u003e5.40 lb, 11 × 6.1 × 4.8 in\u003c\/dd\u003e\n\u003c\/dl\u003e\n\u003ch3\u003eNotices\u003c\/h3\u003e\u003cul\u003e\u003cli\u003eSpecial order item — ships direct from the manufacturer; extended lead times may apply.\u003c\/li\u003e\u003c\/ul\u003e","brand":"Wilwood","offers":[{"title":"Default Title","offer_id":47474058264764,"sku":"120-11329","price":264.9,"currency_code":"USD","in_stock":false}],"url":"https:\/\/bpfauto.com\/products\/wilwood-caliper-forged-superlite-4-1-88-1-75in-pistons-1-25in-disc","provider":"Andrewtech Automotive","version":"1.0","type":"link"}
