What did you do to your NNBS GMT900 Tahoe/Yukon Today?

OK when the driveshaft fails on these big vehicles all kinds of bad $hit can happen , fragmentation can puncture a fuel line or tank.....

I have had good luck with odyssey 34/78 I use the DT (dual terminal),

I forgot about a sidepost connection

I hear the dual posts are hard to keep track of.

yaaa.... lol I felt pretty stupid after I posted that, lol the issue was I have insulators wrapped around the battery's so it was out of sight out of mind.

Are the driveshafts in the NNBS even good for that?

On the GM TRUCK board there was a guy who juiced his Dmax so much and wanted to hit 140. We pointed out to him the OEM driveshafts typically fail 117 mph. The truck had a 105 limiter in the ecm- ithink.....

I suppose it could happen I had my nbs up at 137 numerous extended times, this one the most I have had it up to was 132 but I hit 120 pretty easily often

I can't imagine what a driveshaft coming loose at that speed would do. My front u-joints broke at about 40 on the first run with my supercharger and it just about took out the pan. Oil filter was toast for sure and it dumped oil all over the road. It was pretty damn loud.

what part broke the u-joint?

what part broke the u-joint?

I installed it wrong, over tightened the girdles and they broke. I guess I was in a hurry- installed supercharger, broke trans, installed new trans, broke u-joint. Or else eliminating weak points I guess.

Rain -X is great at anything over 40. I don’t use my wipers much lol. At 80 with Rain-X you’ll never even know it’s raining.

I’ve been using Aquapel the last several years. Usually only have to apply 1 a year

I might have to try it. I apply Rain -X about 4 times a year.

Got under it to brainstorm on how to mount some new driving lights. I think it'd be easier with the bumper cover off, so I'll plan to do the driving lights and LED headlights at the same time. They're driving lights from a 2017 Muffstain GT, taken off when brand new. They're LED and look similar to Morimotos, but I doubt they have anything like the output. I just wanted black LED projector driving lights to forward my un-blinging process. They have four mounting ears in a symmetrical pattern and all on a single plane, so making mounting brackets should be fairly easy. The stock ones are 4" wide, these are 3 5/8". The 3/16" gap won't be noticeable.

Came with the Ford factory mounting brackets and screws. I doubt I'll have any use for the brackets:





The width difference is only 3/8", but it looks like more when comparing side by side:




Stock:




Muffstain:




I think they go better with the factory headlights and will fit in quite nicely.
