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.","brand":"Wilwood","offers":[{"title":"Default Title","offer_id":47641646137590,"sku":"WIL120-13828","price":440.69,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/2170\/2365\/files\/1b2adaec620f01eb0c9d7f7c06ec0b03.jpg?v=1735782610","url":"https:\/\/caliraisedoffroad.com\/products\/wilwood-caliper-forged-superlite-fsl4r-st-aluminum-1-88-1-75in-pistons-81in-disc-ano-right","provider":"Cali Raised Offroad","version":"1.0","type":"link"}
