2003-2007 Cummins 5.9 Injector Rebuild Service

*** PLEASE READ THE ENTIRE DESCRIPTION ***

What is an Injector Rebuild Service?

YOU SEND US YOUR INJECTORS. We rebuild them, test them, and pay for the return shipping back to you. Purchase this service for us to rebuild your set of six (6) Cummins 5.9 fuel injectors.

Why Diesel Injectors So Cal?

Injectors are remanufactured in-house and flow-tested on a state-of-the-art bench to ensure they meet OEM specifications. Injectors for your 5.9 come ready to install with o-ring and copper washer included. We recommend replacing fuel tubes at the same time to avoid contaminants.

What are the Benefits?

You're saving big and receiving remanufactured injectors at a price point similar to the refurbished injectors offered by others. Enjoy smooth acceleration and fuel efficiency again. With the rebuild service, your injectors come with a 12-month, unlimited-mile warranty. Check out our warranty page for more information.

What are the Nozzle Options?

The 30% over stock flow nozzles will work on a stock truck without tuning. The 60% over stock flow nozzles will require a tuner with custom tunes.
