Restore reliable stock-level performance to your 2001–2004 6.6L LB7 Duramax with the Dynomite Diesel NLB7-STK brand-new injector.

This is a genuine new (not remanufactured) stock-horsepower replacement injector built with the latest design revisions for better reliability, consistent fueling, and long-term durability. It is a direct-fit replacement that installs without modifications and requires no core return.

Why Choose the NLB7-STK

LB7 injectors are a common failure point. The NLB7-STK gives you a factory-spec power level injector made from new components rather than a rebuilt unit. You get updated internals and the newest revisions Dynomite incorporates for improved performance and longevity compared with older-style injectors.

Sold individually so you can replace only the injector(s) you need.

Installation Note

The factory LB7 injector lines are prone to rust and internal restriction. If the lines have more than 40,000–50,000 miles, replacing them at the same time is strongly recommended to protect your new injectors.

The Dynomite Diesel NLB7-STK is the straightforward, no-core solution when you want a fresh stock injector with current revisions and a solid warranty.
