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","brand":"Wilwood","offers":[{"title":"Default Title","offer_id":47367914487946,"sku":"WIL-120-13155","price":442.13,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0706\/0619\/2778\/files\/0_3245d3091bac8c6719f4fbc8ede68fee_normalized.jpg?v=1776855923","url":"https:\/\/www.onlyinstock.com\/products\/wilwood-120-13155","provider":"Only In Stock","version":"1.0","type":"link"}
