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-QS 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 Quick-Silver Nickel 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":45681384259737,"sku":"WIL120-13575-N","price":452.17,"currency_code":"USD","in_stock":true}],"url":"https:\/\/battlebornoffroad.com\/products\/wilwood-caliper-forged-superlite-4r-st-r-h-nickel-1-25-1-25in-pistons-0-81in-disc","provider":"Battle Born Offroad","version":"1.0","type":"link"}
