Description

The Industrial Injection 436406 is a CP4 to CP3 Injection Pump Conversion Kit for 2011-2016 6.6L GM Duramax LML engines. It replaces the stock CP4 pump with a more reliable, higher-output CP3 pump. The kit includes a 120% over CP3 Double Dragon Pump, supporting over 900 horsepower. This conversion enhances reliability and prevents damage from CP4 failures. Custom tuning (EFILive or EZ Lynk) is required. Designed for competition use, not legal for sale/use in California for "On-Road," "Off-Road," or "Dual-Use" vehicles.
