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":67637533212985,"sku":"WILW_120-13264","price":485.59,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0276\/3318\/8950\/files\/wilwood-logo-square_543bab0f-7ada-497d-9860-f84911c19a35.jpg?v=1791740315","url":"https:\/\/roco4x4.com\/products\/wilwood-st-fsl4r-caliper-1-88-1-75-1-25-rotor-120-13264","provider":"ROCO 4X4","version":"1.0","type":"link"}
