ATS Aurora 3000 VFR Variable Factory Replacement Turbocharger, 2011-2014 Ford 6.7L Powerstroke. This turbo has up-graded ball bearing packs that are far superior to the factory Ford bearings. The factory turbo charger fails prematurely because of the extra load exerted by the heavy double back compressor wheel. This failure has been eliminated with the upgrade of our HD bearing pack. This turbo is an excellent upgrade over stock when being used to simply replace your failed turbo charger or upgrade the power of your 6.7L Powerstroke Diesel.
