Kinugawa Billet Compressor Wheel For Holset Cummins H1C Turbo - 44/73mm 7+7 Blade | Replaces #3521863

Looking to upgrade or rebuild your Holset Cummins H1C turbocharger?

This Kinugawa billet compressor wheel is a top-tier performance part.

It's designed as a direct replacement for the stock wheel (OEM number 3521863), but it's made from forged aluminum using CNC machining for superior strength and precise balance.

The specs are 44mm inducer and 73mm exducer with a 7+7 blade configuration, and it's rated for high boost levels up to 5 bar (~70 PSI).

Why go billet?

Billet wheels are significantly stronger than traditional cast wheels, making them more resistant to damage from debris and better suited for high-horsepower or competition applications.

This wheel is balanced on a SCHENCK machine in Germany, ensuring smooth, vibration-free operation at high RPMs.

If you're building a performance diesel engine for your Cummins-powered truck and want reliability and power, this is a critical upgrade component.

Ensure it's compatible with your specific H1C turbo model and your performance goals before purchasing.
