The ON3 Performance 7875 Replacement CHRA (Center Housing Rotating Assembly) is a fast, reliable, and cost-effective solution for refreshing your turbocharger without replacing the full unit.
This is a new 7875 turbo core assembly ONLY, and does not include the compressor housing or exhaust housing. Designed specifically for ON3 Performance 78mm turbochargers, this Journal Bearing CHRA allows you to reuse your existing housings while replacing the heart of the turbocharger.
If your turbo is showing signs of wear such as excessive shaft play, oil leakage past the seals, reduced efficiency, or internal damage, replacing the CHRA is often the quickest and simplest way to restore performance.
Rather than sending out an older turbo for rebuilding, balancing, or machine work, this complete replacement core assembly provides a fresh rotating center section—helping reduce downtime while restoring reliability and performance.
By replacing the CHRA, you avoid reusing worn internal components such as shafts, seals, bearings, and rotating hardware, essentially giving your turbocharger a new core assembly without replacing the complete turbo.
The ON3 Performance 7875 Journal Bearing CHRA is an excellent solution for builders wanting a reliable turbo refresh while keeping their existing housings and avoiding the cost and downtime of a full rebuild or replacement turbo.
