2011-2016 Duramax CP4 to CP3 Conversion Kit w/ Pump (436403)
Description
Description
Don't let an unreliable stock CP4 injection pump end the day. The Industrial Injection 436403 CP4-to-CP3 Conversion Kit ditches the CP4 entirely and drops in a proven CP3 pump for the 2011-2016 6.6L Duramax LML, eliminating the catastrophic-failure mode that takes out injectors, rails, and lines downstream.
The CP3 has a long track record for longevity and performance reliability — and it's offered in multiple flow levels so the kit can scale from stock to 900+HP builds. Part Number: 436403
