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\u003c\/div\u003e\u003c\/div\u003e\n\u003c\/div\u003e","brand":"Wilwood","offers":[{"title":"Default Title","offer_id":47276034293947,"sku":"CCP-WIL120-11137","price":278.03,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0637\/5230\/6875\/files\/5737988_0_102.jpg?v=1765476957","url":"https:\/\/motomentum.com\/products\/wilwood-caliper-forged-superlite-4-1-88-1-75in-pistons-81in-disc-mpn-120-11137","provider":"Motomentum","version":"1.0","type":"link"}
