Specs At A Glance

Good To Know

Q: Does this CHRA core include the compressor and turbine housings? A: No, this is the center housing rotating assembly only, so your existing housings are reused during the rebuild. Inspect housings for cracks or scoring before assembly, as damaged housings will cause the new core to fail.

Q: Why choose a CHRA core over a complete turbocharger? A: A CHRA core is a lower-cost option when the housings on your 4.0L turbo are still serviceable. Professional balancing and clean oil lines are essential to protect the new rotating assembly after installation.

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