{"product_id":"holset-wastegate-actuator-kit","title":"Holset Wastegate Actuator Kit","description":"Holset 4030720 Pneumatic Wastegate Actuator Kit. The pneumatic actuator uses boost pressure against a spring-loaded diaphragm to crack the wastegate open once target boost is reached, capping boost and protecting the engine. A ruptured diaphragm or seized rod causes overboost, underboost, boost fault codes and elevated drive pressure. Holset has been the original-equipment turbocharger supplier to Cummins and other heavy-duty diesel manufacturers since the 1950s, and genuine Holset units are built to the same drawing, materials and balance specification as the turbocharger the engine left the factory with.","brand":"Holset","offers":[{"title":"Default Title","offer_id":47134035673261,"sku":"HL-4030720","price":120.59,"currency_code":"USD","in_stock":true}],"url":"https:\/\/www.dfispdx.com\/products\/holset-wastegate-actuator-kit","provider":"Diesel Fuel Injection Service","version":"1.0","type":"link"}
