    Hey guys, I need help trouble shooting my duramax. I was driving today and when I tried to get above 2300ish RPM, it jerked down to maybe 1800 and just bounced around like it’s hitting a low, slow 2 step. It will do it fairly consistently and now the idle surges. Not enough to pick up on the...

    I just recently bought my truck and it’s my first dip into diesel but it just broke down and I know I got something going on with my head gasket possibly looking at other posts.

  13. 2001 - 2007 (GMT800) Non Powertrain
    While I’m driving I can turn one way and it seems my passenger side tire will pull hard whichever way I turned. So with one tire on the ground (driver) I’m able to turn the passenger wheel with my hands back and forth. I replaced my tie rods with ppe stage 3s a while ago and I had no steering...

    I've been rebuilding an 08 LMM with low mileage and we're finally getting into the upkeep and backlog of maintenance on the drivetrain after replacing/repairing/painting panels and other bodywork. It was mentioned to me that I should look into an EGR Delete/Chip setup. I did some searching...

    I ended up purchasing an lbz with a 6" lift and running 38s and was quoted $1500 for removing the lift and return to stock height to its not worth it to me personally, so my question is has anyone lowered the front to 4" or less and if so what was done, I'd like to get down to 4" lift and some...
