Suspension

[swilhite70]

Need help to determine best shock/suspension set up on 3500 dually. Pull a lot of weight and have rear airbags. Even with no load front end bounces up and down going over road swoops.  Feel like it’s coming off the ground.  Any suggestions??

You posted in 1500 forum. I assume a moderator will move to 2500 3500 HD forum. 

 

I would start with a stiff quality aftermarket shock like bilstein

On the company's Sierra Denali 2500HD Duramax we installed a set of Bilstein 5100s. Completely eliminated the pogo effect going down the highway after hitting bumps/imperfections.  Ride is firmer than before but truck feels more controlled unloaded or pulling a 10,500 pound gooseneck trailer.  It is also equipped with rear airbags like your 3500HD.
