What is a CHRA cartridge?

CHRA stands for Center Housing Rotating Assembly. It's the core of the turbocharger, containing the shaft, compressor wheel, turbine wheel, and the bearings that allow them to spin at high speeds. Replacing the CHRA is a common way to repair a failing turbocharger.

Why is the dual ball bearing system important?

The dual ball bearing system significantly reduces friction compared to traditional journal bearings. This leads to faster turbo spool-up, meaning the engine reaches boost pressure more quickly, and also offers greater durability and longevity, especially under high-stress conditions.

What does 'Not CARB approved' mean?

CARB (California Air Resources Board) approval means a part meets strict emissions standards for use in California. If a part is not CARB approved, it cannot be legally installed on a vehicle registered in California due to emissions regulations.

BorgWarner is a well-known name in turbocharger technology, and this cartridge reflects their commitment to providing reliable, high-performance parts. When rebuilding or repairing your turbo, using a quality CHRA like this one is essential for achieving optimal boost levels and maintaining engine power.

If you're experiencing issues with your current turbocharger, such as reduced power, excessive smoke, or unusual noises, replacing the CHRA is often a cost-effective solution compared to a complete turbo unit replacement.
