Suspension Upgrade Questions?

I took my new truck camper for its maiden voyage this weekend. I weighed it at the cat scales. The unit weighs 3100# loaded.
The GAWR Rear of my truck is 6,100# and I'm right there.
The GAWR front is 4,600# and the front loaded weight is 4,100#

I have a 2004 GMC Sierra 2500HD with 66,000 miles.

This is my first truck camper.

It drives very wallowy. There is excessive body roll also in my opinion, or at least more than I am comfortable with.

The shocks definitely need more damping ability since the truck bounces up and down sometimes like it needs more compression and rebound damping. They are overloaded in my opinion.

I think air bags could help the body roll too.

So for shocks which brand should I get?

For air bags which brand should I get?

What other suspension components, upgrades, or adjustments will help the truck to drive more stable down the road?

Thanks.

  • IMO, I would get Bilstein shocks for dampening. Then I would get Supersprings to assist your 2500 and you will also notice an improvement in sway reduction.
  • You'll find a thousand and one opinions on this topic here for sure...the one constant theme you'll see over and again is the idea to upgrade gradually (one component at a time).

    I'd start with a set of stable loads from Tork Lift for sure...again a common first step, that you can install easily for very little investment. Then see how that goes.

    If you still aren't happy consider a set of Timbrens! These are airless airbags that are install an forget (like the stable loads), and you can install yourself for very little investment. My personnel opinion is that air bags is kind of the old way of doing things....there are better products out there now that make air bags obsolete.

    Once you've tested that you might want to consider rear sway bars, a leaf spring pack rebuild (best option but will run about $1400), new shocks...I like Bliesteins, 19.5 wheels and tires that are G or better rated! Certainly you should have E rated tires on your truck already at a minimum!

    Hope that helps...feel free to PM me too if you want!
  • This is a subject well covered many times, you could do a search and find many opinions. BUT you asked:

    I would try these things first one at a time till you feel comfortable:

    Stable Loads - By Torklift (I would have them but the dodge 1 ton SRW springs require drilling a hole through them, I am not up to it)

    If that is not enough:

    Bigwig Rear Sway Bar - By Hellwig(got one myself and it was a good investment, like the improved handling and less sway)

    If these two items do not help enough, many people go with Timbrens or added spring leafs. have no actual experience with either.

    If the truck is bouncing up and down and you determine yoou need shocks, I would look at either Bilsteins or Rancho's. I went with the Bilsteins, they did help the truck handle better but do not noticeable help with sway. The Ranchos have a huge following but cost more, both are very good.

    I have Firestone Airbags with individual control, they came on my 2010 that I bought preowned. they DO NOT help stop sway, they DO level the truck. If I was doing it from scratch, I would go Stable Loads, have heard so many good things, great company.

    If these things do not help- one ton dually, wish I went that way when purchasing my truck.
  • I have a Ford dually and haul a 3400# dry weight Lance 1121, about 4300#s locked and loaded. I've used Ride-Rite air bags and Rancho 9000s (shocks) with good success the past 9 years and over 200k miles.
