Default Help to upgrade Suspension of 2005 Chevrolet 2500

So earlier this year I bought a 2005 Chevrolet 2500 6.0L Gas 4x4. Use of the truck is only pulling the boat. The ride is terrible. It's not normal 3/4 terrible, it needs work. It also sits pretty low with the boat attached.

Does being lifted have anything to do with the terrible ride? Where do I start? What parts do I need to look for?

Here is a bad picture of it.

I'm guessing torsion axles have been cranked to get front end up. That will definitely make it ride like hell. I have 2003 2500. 5100's on it and michilens made it ride alot better than stock, but it still rides like a brick compared to my half ton.

Doesn't appear to be lifted much. Check the torsion bar bolts, if they are bottomed out, the "pork chop" is cranked beyond were it should be, a cheap mans "lift"

bilstein shocks all the way around and air tires down a notch as mentioned before. also tires that are a few years old will stiffen and make the ride a little rougher.

other than that, its a 3/4 tun suspension so it will not be great by any means

I have done all the normal mods to 2500 and 3500 chevy's with the same result....a shit ride.

Until I learned about Norcal Nick and Cognito suspension for these trucks I thought I knew it all.

I would seriously consider putting a Cognito kit on the front. The change in the ride is just amazing. People can't believe how well my '16 one ton crew cab long bed rides.

Also, if you're running 80 psi in the front tires, it WILL ride like shit. Rattle your teeth out. It's supposed to be 50 psi in front, 80 in rear. Check sticker inside of door.

Thanks everybody. Will check the tires and torsion bars.

How hard of a job is changing shocks?

A little harder than brushing your teeth.

My preference for a leveling kit is BDS with the Fox 2.0 shocks. From memory the 2006 range of those trucks need the airbags just like most 1/2 truck to tow.

Best thing I did to get a better ride out if the 2500 is park a half ton next to it and drive that when 3/4 ain't needed.

The 2500's that I've owned, all stock trucks with no suspension mods, need at least 750 lbs. in the bed to smooth the ride. They're made to carry weight, and they just don't ride well empty.

As suggested, lowering the tire pressures will help also. No need to run 80 psi in the rear unless you're loaded.

But they still don't ride like a 1500.

I had my tire pressure monitor reset to 40#'s...huge difference in ride, tire wear is even.

Soak the shock nouts in PB blaster for a couple days, should be fairly straightforward.

An impact wrench (electric or pneumatic) with a deep well socket is the ONLY way to do those top nuts on the shocks. They come off is seconds. Doing them by hand is a real PITA.

I am in the process of doing this.... Actually going Yukon XL with a hefty pickup next to it...

May even go 350/3500...

When I add 500 pounds in the far rear of the bed to aid plowing in the winter, it transforms the ride but I don't feel that a solution for the other 9 months of the year. I have also aired down and bought 5100 bilsteins this week but have yet to install them. I've read good things about Solastic shackles but have not ridden in a vehicle equipped with them.

That seems a little low for a 2500, I run 50 in the front and 60 in the back of mine. It rides pretty good but hates the brick streets they have in the Tampa/ St Pete area.
