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":40142105346147,"sku":"WIL120-11331","price":461.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0078\/3122\/4409\/products\/e2f1b906f7759ffafaa2c7f6de201339_fc44ecb9-5094-41bd-8d3e-72ac00515ede.jpg?v=1667079056","url":"https:\/\/honeycombmotorsports.com\/products\/wilwood-caliper-forged-superlite-4-st-1-88-1-75in-pistons-1-25in-disc-2","provider":"HoneyComb Motorsports Inc","version":"1.0","type":"link"}
