I got 85k out of the sticks replaced by GM. Just put another 100k on the third set and they are coming out on Monday. Replacing the fuel lines from the rails to the injectors. Heard from several tech at the local GM shop that the old line are killing the newer injectors because they are breaking down inside. Need to make it to 500K.

I have 150k on my original injectors and they are all within spec. My friend has 240k on his original lb7 injectors, also all with spec.

According to carfax, mine were repalced at 156K. Truck now has 244K, but it has an engine from an 02, so no telling how long they've been in it. Injector 7 is out of whack by +-.02

I have 143k on my first original set. Buddy of mine has 291k on his lb7 as well on stock set of injectors. Its all how you maintain your truck. I'm hoping to get 250k+ on my stock set. I run additives, change fuel filter an do everything I can to make em last

Since this time (4th) I am replacing mine, along with the lines from the rails, I will be very interested to see how much longer they will last. I run additive, lift pump and CAT 2 micron, but all of that is useless if the inside of the lines are coming apart and killing the injectors. I've averaged less than 75k on the three replacement sets.

I think I am better off to sell my lb7 for a lbz or lmm. I love my truck and its never let me down, but I am not going to do injectors every 2 years. I had a cummins with 375k when I sold it and it never had one problem. This truck has 116k and it could need a 2nd set of injectors any day now! Thats fu4ked up! Its to bad because aside from the injectors the lb7 is the best truck made

That was a special policy on original LB7 injectors.
