The Garrett G25-550-RR CHRA is a purpose-built center housing rotating assembly engineered for builders who need reverse-rotation geometry without sacrificing the performance pedigree of the G-Series lineup. This configuration is built for platforms where standard turbine and compressor orientation won’t work, giving tuners and fabricators the flexibility to package boost exactly where it’s needed. It’s the choice for enthusiasts who demand proven Garrett engineering combined with non-standard mounting versatility.

Performance & Application
This CHRA is designed for high-boost applications where power output up to the rated capacity is the goal. The ball-bearing core delivers the fast-spooling response and durability Garrett’s G-Series is known for, while the reverse-rotation layout opens up mounting solutions not possible with standard-rotation hardware. It’s built for enthusiasts and shops tackling custom turbo system layouts that demand non-standard geometry. Applications requiring this specific rotation configuration will find this CHRA purpose-matched to that need.
