The SPOOLOGIC High & Low Pressure Stock Turbo Cartridges SL-200-034 is a matched pair of complete VSR-balanced turbocharger CHRA cartridges — both low-pressure (LP) and high-pressure (HP) center housing rotating assemblies pre-assembled with shaft, turbine wheel, compressor wheel, extreme duty journal bearings and spacer, 360° thrust bearing and collars, and a full set of seals — dynamically balanced for 6.4L Powerstroke applications. Covers the complete 2008–2010 6.4L Powerstroke variable-geometry compound turbo system — the LP CHRA uses the SPOOLOGIC SL-220-020 7+7 cast compressor wheel and the HP CHRA uses the SPOOLOGIC SL-220-021 7+7 cast compressor wheel. Ships with both CHRA cartridges (LP and HP) and one turbo install gasket kit covering the complete compound turbo assembly.

What’s Inside the CHRA

• Turbine shaft & wheel — balanced, high-nickel inconel turbine wheel welded to the shaft as a single rotating unit.
• Compressor wheels — matched LP + HP set for the 6.4L compound turbo system.
• Extreme duty journal bearings & bearing spacer — upgraded bearing material for improved thermal tolerance and longer service life.
• 360° thrust bearing & thrust collars — upgraded from OEM half-thrust design for better axial load capacity.
• Step gap seal rings — compressor and turbine side, replacing worn OE seals for tight oil control.
• Center housing — original SPOOLOGIC casting, machined and inspected before assembly.

VSR-Balanced as a Complete Assembly

Balancing a CHRA is not the same as balancing a bare wheel. This cartridge is dynamically balanced as a complete rotating assembly on a VSR (Vibration Sorting Rig) balancer — the industry standard for verifying that the shaft, turbine wheel, compressor wheel, and bearing system all spin true together at operating speed. A wheel that reads balanced on a static bench can still fail a VSR check once assembled — and a CHRA that fails VSR will not leave our facility.
