Upgrade truck suspension
Hi all, Just on the shakedown trip with the new rig, a NL 8-11 and a 2019 Chevy 3500HD Duramax. Over all I am happy with most of the handling, certainly the acceleration and pulling power is fine....

If the shocks made no difference, it sounds more like death wobble not porposing. That would mean your suspension parts could be worn, out of alignment, or stabilizer worn out or all. You can read about death wobble on Ford trucks at the Ford-trucks.com site.
The bandaid is adding a double shock steering stabilizer in addition to your stock one.
Porpoising is an out of balance issue. The front and rear are responding at dramatically different rates which cause the rocking. If you changed your shocks on the rear to 1 for example, you should see a different behavior. That being said, I ran 6 in front and 9 in back with my 9000s when I had a SRW, so those numbers are what I would expect.
If shocks were going to help, you should have already seen the benefit.
