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":47367920124042,"sku":"WIL-120-11137","price":264.9,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0706\/0619\/2778\/files\/0_5005b5ddd90ef109b9531b99ba7e5a8a_normalized.jpg?v=1776855941","url":"https:\/\/www.onlyinstock.com\/products\/wilwood-120-11137-caliper-forged-superlite-4-188-175in-pistons-81in-disc","provider":"Only In Stock","version":"1.0","type":"link"}
