Fits: 2007.5 thru 2010 Chevy Silverado/GMC Sierra 2500HD/3500HD LMM Duramax Diesel 

The 60% over-injectors are available new or remanufactured and then honed and balanced to the desirable flow rate. These 60% over injectors work great in trucks with turbo and tuning upgrades. At this level of Injection, it is required to upgrade to a higher flowing fuel pump or a dual CP3 setup, both with a lift pump.

Once the nozzles are opened up to the desired flow percentage, then the injector is reassembled and the set is balanced to within +/- 5%.
