GMT800 Airbag kit
Hi all! I am considering taking the airbags off my 04 Sierra and was wondering if any member here might be interested in the whole kit. With my truck being lowered, the airbags have made the suspension extremely stiff. They have also caused a "stinkbug" stance that I can's stand. I could source...- INW-Iron-Steel

GMT800 Dilemma
Guys, I am seeking a little input from those who have been around the block a few more times than I have. My grandfather is in his 80s, and is not in the greatest health. He has a SWEET dodge that he has been telling me for the better part of 15 years that he is going to gift to me when he is...- INW-Iron-Steel

Bosch Alternator Good Buy
Hi all, Just thought I would share this in case anyone is in need of an alternator. The reman one made it 10 years or so, but it was on its last legs. These trucks mainly came with either an ad230 or ad244 alternator. The early year ad244 was rated at 130 amps while the later trucks got 145 amp...- INW-Iron-Steel

Oxygen Sensor Heater Codes
I changed the upstream O2 sensors on my 04 Sierra this last week and now I am getting P0135 and P0155 heater performance codes for the corresponding sensors. Two things I think are strange. 1- I didn't have either of these codes before starting. 2- It can take multiple days and many trips for...- INW-Iron-Steel

HVAC Controls
Does anyone know of a source other than Dorman to get HVAC controls from? Mine has been dying for a number of years, but it is getting worse now. A few years back my AC wasn't working. A friend of mine and I traced it back to the actual AC button/switch on the board in the HVAC control...- INW-Iron-Steel

FEDEX RANT
Just as the title says, this is going to be a rant. I need to get this off my chest. I ordered some parts last week from RA and paid extra for 2-day guaranteed shipping so they would be here when I finished my weekend shifts on Monday. Within a day box went from Colorado to Iowa, and then...- INW-Iron-Steel

Fuel Pump Replacement
My 04 Sierra currently has 265,000 miles on it. I am working on a set of custom leaf springs to replace the worn out, saggy springs in my truck. As the weather warms up I am going to be swapping them in. But, that brings me to my dilemma. To pull the front bolt on the driver side spring I must...- INW-Iron-Steel

2004 RCSB 4x4 - The Mail Truck
This is my much beloved 2004 Sierra 1500. I have modded this truck a lot over the years. I'll post the mods up in this build thread, as well as future modifications I have in mind.

New here, but not to the GMT800
Hi all, I am a recent convert from GMT400 forum. Had no idea the GMT800 forum was a thing until @ORVietVet enlightened me! Thanks for that! I have grown up working on the 800 platform as these were cheap and plentiful for my friends and I to wrench on in high-school. I turned all of my friends...- INW-Iron-Steel
