This injector rebuild service is for the 2001-2004 model years for Chevrolet Duramax LB7 diesels.

This is a rebuild service for your eight (8) diesel injectors. Please read - For this service we will do the following:

- Completely disassemble and clean in our Vapor Honing machine

- All springs are replaced

- Ball bearings are replaced

- New bearing supports are installed

- New internal seals are installed

Please Note: 30% over stock flow nozzles will work on a stock truck. 60% over stock flow nozzles will require a tuner with custom tunes.

We absolutely recommend replacing high pressure fuel lines whenever you replace injectors. Doing so will help to extend the service life of your injectors and prevent contaminating your freshly built with particles from old lines.
