Yep. Viking... I had to modify the atomic brackets at the bottom to fit my newer stamped lower control arms, but other than that, It was a piece of cake. I think I should have gotten the shocks with the higher dampening, since I like it tight, and it appears that having the vikings at nealy the max setting, you could hear them squeaking a bit. I believe I'm hearing the oil pushing around the orifices. I may be wrong, but I'm not sure yet. I might see what I can do to change the vavling and get back with results.

I installed Rancho 9000s just to help with the bounce since the stock shocks were marginal when unloaded. It vibrated unloaded or loaded before and still does so no answers here. I have a daily weight of 5900-6000lbs loaded and with the weight it is level front to rear. Thinking Ill do axle mods and driveshaft balance at some point.
you can test the axles without any hard work , ds should be the first to test

I put the coilovers back on, which reduced the shake again considerably.... If you're happy with your ride height and would like to retain most of your stock suspension, I'd look for a factory replacement strut with adjustable dampening. I'm switching my whole setup again, going to try Bilstein 5100 struts with stock springs. They're not adjustable as far as compression and rebound, but I've had a lot of good luck with them in the past. I should have it all by next week, and I'll let you know if that strut helps with the issue as well.

6.2L/L86, 8L90e, extended cab standard box... NHT truck. 1 piece aluminum driveshaft. No lift block in the rear.
It shakes from ~65-90. Goes away at 88-92.
I had the torque converter, lines, filter, radiator, AC condenser, and trans cooler replaced under warranty. The radiator is pissing coolant again but I digress
Two sets of tires, same shake, different speed (slightly different size). That means it is driveline related. It didn't start doing it until ~38k miles (after the new torque converter). It has 53k on it now.
My cousin works for a GM dealership. He says there is a TSB for ring/pinion issues.
Contemplating just getting the driveshaft rebalanced or retubed. Or a new one made. What do you guys think?

IMO kind of hard to say what may or may not work. In my case i had a nice dennys driveshaft made good to 10000 rpm. To my disappointment still had the shake. On the other hand guys like 07softail had his checked balance was good run out was high. said he got that fixed and was 90 percent better. I think another guy found out of round axle flanges. Just BS these trucks are so nice but gm cant fix this issue. I really liked my truck ,but the shake would enrage me every time i drove it, Sadly i got rid of it because of that issue and i was tired of throwing money and parts at it. Wrath not trying to be the "negative Nancy". I hope you are able to resolve your shake
