Fits: 2006 thru 2007 Chevy Silverado/GMC Sierra 2500HD/3500HD LBZ 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 are great on trucks with an upgraded turb and tuning, however, at this level of injection we recommend upgrading to a higher flowing injection pump or a dual CP3 set up, bot 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 +/- 4%.
