The original actuator design can fail when internal pins separate from the printed circuit board, so this OE FIX version uses soldered compliant pins to create a more secure electrical connection. That design change helps reduce repeat failures caused by normal heat cycling and vibration.\u003c\/p\u003e\u003cp\u003eThis part cross-references Mopar R8481772AA for the same application. It is a direct-fit turbocharger actuator solution for Ram 2500 and Ram 3500 models, with additional fitment listed for Ram 4500, Ram 5500, and Ram 4000. The 668-100 is remanufactured in the USA and tested to help restore proper turbo boost control.\u003c\/p\u003e\u003ch2\u003eWhat It Helps Address\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eLoss of turbo boost control\u003c\/li\u003e\n\u003cli\u003eFaults caused by actuator electrical connection failure\u003c\/li\u003e\n\u003cli\u003eRepeat failures from heat and vibration exposure\u003c\/li\u003e\n\u003cli\u003eDriveability issues related to variable geometry turbo operation\u003c\/li\u003e\n\u003cli\u003eNeed for a remanufactured replacement actuator\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Notes and Tips\u003c\/h2\u003e\u003cp\u003eVerify fitment by year, make, model, and application notes before installation. This actuator uses an electronic activation type, a male connector, and blade terminals, so connector and terminal style should be matched to the original unit. Mounting hardware is listed in the product data, but confirm application-specific requirements during service.\u003c\/p\u003e\u003ch2\u003eQuality Assurance\u003c\/h2\u003e\u003cp\u003eDorman remanufactures this actuator to industry standards in the USA and tests it to help restore factory-spec turbo boost pressure. The upgraded internal connection design is intended to address the failure mode seen in the original actuator.\u003c\/p\u003e","brand":"Dorman","offers":[{"title":"Default Title","offer_id":53342670946485,"sku":"BKKY-668-100","price":852.42,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0628\/1442\/1173\/files\/RB_668100_Fro.jpg?v=1789796224","url":"https:\/\/www.partcatalog.com\/products\/dorman-668-100-turbocharger-actuator","provider":"PartCatalog","version":"1.0","type":"link"}
