This professional TO4B rebuild kit will fix up your 6.9 or 7.3 093 late model ATS turbo, also known as the 1993-1994 7.3L IDI turbodiesel turbocharger. It comes with new seals, bolts, journal bearings, thrust bearing, rings and all necessary parts to do a standard proper rebuild. Please note, that if you have never rebuilt a turbocharger before, we strongly urge you to consider letting us do it. If you break off bolts that are siezed, damage the turbine shaft or wheel, or cause other problems, you may render the turbo un-rebuildable. Please note once the kit is opened, it cannot be returned, or refunded.
