Specs At A Glance

Good To Know

Q: Do I need to rebalance the assembly after installation? A: The cartridge comes as a balanced unit, but many shops still verify balance and clearances during a rebuild. Follow your service manual for the exact procedure.

Q: Can I install this without removing the whole turbo? A: The CHRA is typically fitted with the turbo off the vehicle and the housings separated. Installing it on the bench is the standard method.

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