INDUSTRIAL INJECTION 43A603 GM DUAL CP3 MACHINED WHEEL FOR 01-10 6.6L DURAMAX

The INDUSTRIAL INJECTION 43A603 GM DUAL CP3 MACHINED WHEEL FOR 01-10 6.6L DURAMAX is a precision-machined, direct-bolt replacement CP3 cam gear wheel designed for owners of 2001–2010 6.6L Duramax engines. This wheel allows you to convert a single-plunger CP3 pump into a dual CP3 setup, improving flow, reducing pressure pulses, and enabling higher injector/demand capability.

Manufactured from high-grade billet stainless steel, this machined wheel is engineered for exact OEM mounting tolerances and superior reliability. It’s ideal for high horsepower builds, severe duty trucks, or anyone upgrading to dual CP3 pump configurations. It retains OEM bolt patterns, fits standard input shafts, and uses factory hardware (or recommended upgraded bolts) for secure installation.

Key Features & Benefits:

• Direct-fit for 2001–2010 6.6L Duramax (LB7, LLY, LBZ, LMM, etc.)
• Milled to tight tolerances to maintain factory timing and alignment
• Fits both OEM and aftermarket dual CP3 layouts
• Supports higher flow rates and reduces pulsation in high-demand applications
• Compatible with standard CP3 pumps and injector rails

With this wheel, you maintain the factory geometry and alignment of your CP3 setup while unlocking elevated fuel delivery for performance builds. It’s the perfect companion to upgraded dual CP3 pump systems.

Frequently Asked Questions (FAQ)

Is this wheel compatible with all 6.6L Duramax models from 2001 to 2010?

Yes — this wheel is designed to replace the factory CP3 drive wheel on LB7, LLY, LBZ, and LMM Duramax engines (2001-2010). Ensure your CP3 pump location and spacing match standard layout.

Can I reuse my factory mounting bolts?

We recommend using high-strength bolts rated for performance use — stock hardware may not be sufficient under high boost or high duty cycling. Consider our reinforced bolt set.

Does this wheel change injector timing or require retiming?

No — it is precisely machined to maintain OEM alignment and timing geometry. When installed correctly, no timing adjustment is required.

Will this wheel support flows for extreme horsepower (e.g. 1,000+ hp)?

Yes — when combined with dual CP3 pumps and proper supporting fuel system components, this wheel is suitable for very high flow demands.
