Fits: 2001 thru 2004 Chevy Silverado/GMC Sierra 2500HD/3500HD LB7 Duramax Diesel 

The Industrial Injection 75% over R5 Injectors start out as a genuine stock remanufactured injector from the factory then have been extrude honed and balanced to a perfect matching set injectors that flow 35LPM. The R5 75% over injectors should be ran a single S400 or compound turbo setup to run more efficiently and to help reduce EGTs. Also recommend a CP3 upgrade like the 120% over Double Dragon Fire Pump or Dual CP3 Kit. We typically see a 1-3MPG increase in fuel economy. This is a 100% OEM Reman Injector directly from the factory themselves simply sold and modified by Industrial Injection. When replacing the injectors in your LB7 Duramax we highly recommend replacing the injector fuel lines to avoid new injector contamination. The most common failure of new injector installations is contamination and the problem that we see most on these comes from the fuel lines.
