Specs At A Glance

Good To Know

Q: Do I need to rebalance the turbo after installing this CHRA core set? A: The rotating assembly comes as a matched unit, but many installers still have the completed turbo balanced and the oil feed cleaned before fitting. Confirm the procedure with your turbo rebuilder.

Q: Will this core set fit both turbos on the 4.0L? A: This is a set for the twin-turbo 4.0L layout, so check the listing specifics against your engine code and turbo positions before ordering. Fitment can vary by model year and serial number.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
