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. Featuring a wear resistant Type III hard anodize finish, 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":46962850758823,"sku":"WIL120-13828","price":486.79,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0555\/8344\/1063\/files\/1b2adaec620f01eb0c9d7f7c06ec0b03.jpg?v=1755489553","url":"https:\/\/www.straightsiximports.com\/en-us\/products\/wilwood-caliper-forged-superlite-fsl4r-st-aluminum-1-88-1-75in-pistons-81in-disc-ano-right","provider":"Straight Six Imports","version":"1.0","type":"link"}
