what is the best bang for the buck on lb7 injectors? my truck has 225k and i love it. i do not want to change these again. and this will be the first set. i have read a lot of negativity about reman injectors. does anyone warranty them past 1 year?

 

You can get new ones from Dynomite Diesel.

 

Duramax LB7 Fuel Injector<link to merchants site

Merchant sells NEW BOSCH injectors if you want OEM tips, these also use the revised body to help eliminate cracking

The DDP injectors will be good if you want more fuel than stock, but they are really only needed if you plan on going into the 600rwhp+ range

 

Just bought and installed a full set straight thru my GMC dealer. Remans---$250.00 each, plus $100 core. Be prepared to get the install kit too--includes lower valve cover gaskets. I put them in, fired it up, then drove 1000 miles round trip to Bristol for the NASCAR race. Runs like new and my smoke problem is long gone!

 

Is the fix for the lb7 injector saga, or just keep changing injectors. Mine has the third set starting to smoke again at 175k miles.
