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":43622379978979,"sku":"WIL120-13266","price":468.61,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0630\/6607\/9459\/products\/ca5b0462d68aff2f0d6b58941f68f1d3.jpg?v=1672181244","url":"https:\/\/shop.middletonmotorsports.net\/products\/wilwood-caliper-forged-superlite-4r-st-l-h-1-88-1-62in-pistons-1-25in-disc","provider":"MM Parts","version":"1.0","type":"link"}
