Awesome! Hopefully others with the same issue will find this post.

Yeah its crazy. I have another vehicle with a 7-8 year old Walmart battery that is still going strong. I can't believe GM is so cheap they went with an even cheaper battery than Walmart brand!

Hey all. I had this resolved. I know its been a while but I wanted to get a driving test in before replying and haven't really drove the truck at night all summer! Anyway, when I brought it in for maintenance they did a load test on the battery and pulled some codes from the truck, (I didn't have any error lights on). Apparently there were several codes for low voltage. Also the battery test came back as "flooded". They replaced the battery and all was well. Hope this helps.

Yes, the transfer case shaft to the front differential.

Yeah I am hoping the rear is fine because its only 1" and the blocks were tapered. Its the front 4x4 I am mostly worried about since the front is up 1.85".

I'm not but didn't want to prematurely wear out anything without noticing symptoms.

Hey all, I didn't really think about this when installed but had a friend ask me if I did anything about the new driveshaft angle for the 4X4 and main shaft. I installed the 5100's on max setting and added a 1" raise in the the back. The Motofab blocks had a taper to maintain the angle, (I think) but now I am worried about it being correct and if I need to do a transfer case drop? Do you think that it is lifted enough to worry about? I cant really tell by looking.

What does tow mode actually do other than run the gears out longer. I tow a 3000lb camper and never put it in tow mode because I hate seeing the engine rev that high.

I did get an update that increased the voltage, (supposedly). I think it made no difference. I will most likely take it in under warranty too. Just hate to if it is something that I can fix in the driveway like a loose wire. Battery cables seem fine.

Hey all. 2015 Sierra SLE. I have searched a bit for this issue but haven't really found the same symptoms. I only notice it at night of course. When I am on the brakes, the headlights dim a bit. Then if the fog lights are on, it is even more noticeable. If I have the stock radio playing and there is a decent amount of base, I can see the headlights flicker to the tune, (fine if I was at a club). Also if I turn a blinker on, you can see the lights dim on and off. I saw some posts about G218 but they seemed more related to internal stuff. I only notice this in the exterior lights. Any ideas? I suspect maybe a weak ground connection somewhere? Thanks for any input.

Yes they can. No you wouldn't need one since you are not changing the angle. If you added a block, (even +1") you would need an alignment. Somehow that changes the front angles enough to require one. Or so I am told from the guy that aligned mine.

If everything is torqued, I would also suspect the link. Maybe remove it and check for play.

Just added the 5100's all the way around. Front is at max setting and I added a Motofab 1" block in the rear. I have to say that I am ok with the front ride but the ass end of the truck seems to bounce or "skitter" over bumps. It did this with the Rancho's as well. I was hoping that replacing with the 5100's would stop this. I torqued all the nuts on the U bolts to 60 lbs and verified the shocks were mounted correctly, (boots down) and functional. With some weight in the back, it rides fine. I understand its a truck and will ride like one but I am disappointed in what I expected of the upgrade. My father and brother both have Tundra's and man do they ride great. Its a nice solid bump and then done. Not a skitter like my Sierra. Has anyone else noticed this and have recommendations? Or am I expecting too much?

I have them set on the top notch and the ride is great. Better than the Rancho's for sure. I also added a 1" lift in the back to keep the rake since I haul a travel trailer. Next is to replace the rears with 5100's too. You wont be disappointed if you go to the 4th notch. It basically put my nose up almost 2" and left me with about .5" rake, (then I added the rear block).

Crap! Good catch.
