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.","brand":"Wilwood","offers":[{"title":"Default Title","offer_id":54788162715994,"sku":"WIL120-11332","price":622.07,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0950\/7441\/9034\/files\/6b7cf8db702c01198a7f82c7b4db4399.jpg?v=1789402869","url":"https:\/\/mprtruckparts.nl\/en\/products\/wilwood-caliper-forged-superlite-4-st-1-88-1-75in-pistons-1-25in-disc-1","provider":"MPRTruckParts","version":"1.0","type":"link"}
