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":45106623512739,"sku":"WIL120-11329","price":240.82,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0656\/8430\/8131\/files\/91ab364fac7d5d1e627333af52a04bad.jpg?v=1723944119","url":"https:\/\/mo-moto.com\/products\/wilwood-caliper-forged-superlite-4-1-88-1-75in-pistons-1-25in-disc","provider":"Mo-Moto","version":"1.0","type":"link"}
