Shocks for 2016 GMC 3500HD Denali Dually

2016 GMC Denali 3500 Dually, crew cab, long bed, duramax with 2017 Host Mammoth. Already has airbags and Stable loads (upper and lower). Air bags keep the rear sag to a minimum. The problem is expansion joints and the wonderful dips the “engineers” have left us. The truck seems to leap, so I’m assuming this is what is known as a rebound issue. I imagine that the truck is compressing into the overloads as designed, but hopping back out.

Do I need front and rear shocks? Bilsteins? Rancho? Some post seems to indicate that the nose (front shocks) may be issue ...

How does one learn the wheel weight capacity? My inner rears are steel (i think) and the fronts and outer rears are (what looks like) polished aluminum. Stock tires are little 17 inchers.
  • Bilsteien shocks have the best rebound dampening I have found. They settle a trailer that want's to pull upward on the truck or porpoise.
  • Shocks do nothing for ride height or loading. Their sole function is rebound. So do you need new shocks? Under thst load it sure would be a good idea. Unless someone has changed them you have 6 steel wheels. Your weakest link is tires. There is nothing you can do to alter or increase load carrying capacity. The weight sticker on the truck is a federaly mandated sticker that cannot be altered.
    Shock brand? Bilsteins seem to be one of the best. What ever brand you pick dont get the cheapest model.
