A rebuild kit can delay, but is not a substitute for our fully remanufactured injectors. If you have high mileage injectors or a catastrophic injector failure we recommend our remanufactured injectors.

This is the #1 injector rebuild kit ever offered for the 1994-2003 7.3L Powerstroke Diesels. This kit contains everything needed to rebuild all 8 injectors. We source all of our injector parts from USA and Italy giving you the best combination of quality and price! Don't waste your time with cheap o-rings from China. This kit includes the best o-rings on the market. The external o-rings by Alliant Power, the OEM supplier for Powerstroke/International injectors are manufactured by Parker. We have included stainless steel poppet valve shims and solenoid shims. If the clearance between your armature plate and adapter plate is causing cold start issues you can use the supplied shims to increase the clearance near factory specification. This will fix the some of the issues caused by a worn poppet valve/poppet valve seat. Our rebuild kit is used all around the world to rebuild HEUI injectors. We have put together all of the normal wear items typically found in these injectors to save you time and money. We can help you replace other components if you find damage after tear down. There are many Youtube videos that can help you if you have not done this before. Combine this rebuild kit with our rebuild tool for a seamless rebuild.
