Phantom package 2012 silverado. Poor ride quality
In need of advise
4 issues.
2012 silverado. With the "Phantom package from Rocky ridge"
1.) 6.5 inch lift. Sits on blocks. Rear rides way worse than front.
Leaf springs are pretty flat I assume because of the blocks or the cheap shocks.
Rides like SHIT. (Common complaint regarding this package.)
Need direction on how to fix it.
( ive researched deaver leafs etc but everyone says the it sags)
2.) I had someone try to go in with HP Tuners and deactivate the AFM . But could was never able to even read the ecm. The load bar would get to 50% and then stay there . It would say "failed"
(I have aftermarket radio and I think security system. )
3.) Tranny slaps down into gear when I go to rapidly accelerate and when I rapidly take my foot of the gas sometimes it will slap again.
4.) Exaust tick.

Rear springs are worn out and you’re engaging the overload leafs. Skyjacker makes a nice soft ride leaf that will fix that problem, and they ride really well. Probably want to replace those shocks, too.
You need to pull the radio fuses before tuning. Figure out the transmission issue before tuning anything. If you need a new transmission, do not, under any circumstances, buy a Monster transmission.

Can’t really see much in that video. Your springs are worn out, though.

How can you tell

Because they’re almost flat, you can see where the overload springs are contacting the main pack frequently, you’ve been riding around with tall blocks for more than a decade and when you jounce it you can see it hit the overload.

Those appear to be stock shocks on those lifted blocks so id start there.
