softest suspension

Man I haven't posted on here in a long time but I am looking for a few answers and all help would be greatly appreciated.

First off, I own a 2008 f250 4x4 with the 6.4, it has a rough country 2.5" leveling kit with 20" wheels and 35" toyo mt's. The ride on this thing is absolutely awful. My last truck was a 7.3 with a 6" lift and 37's and it was a much softer ride along with the front springs being pro comps. Also, I was looking at it today while changing my oil and in the front the amount of travel I have is incredibly small... there might be 3" between the axle and bump stop but it's closer to 2".
As far as driving I don't go offroad much at all, but would probably be willing to more if it rode better, and I tow a 24' wakeboard boat about twice a week during the summer. Other than that it stays on concrete

So heres what I'm interested in hearing about:
Carli 2.5 pintop leveling kit- this is the most expensive but everyone raves about carli, and it has 9" of travel in the front. Much improved, but what does it? is it just the spring and shock combo? Could I not source out springs and shocks and maybe get the same ride quality for cheaper?

Pure performance has a few kits and I've heard good things about them so hows the ride quality?

Carli uses radius arms, but I would possibly be willing to go up to a 4.5" kit and put 37's on it at some point. How are the 4 link kits as far as ride quality and wheel travel?

And for the back, I have towing airbags now but don't use them even for the boat. Whats the best thing to do for the back? I've heard about the '11 spring swap? but does it make that big of a difference?
And for now I think thats it, any help or insight is greatly appreciated and I do understand its a large truck and wont ride like a lexus, but how it is now really needs improving.
Thanks

First thing to look at is your shocks, I have Rancho 9000 series and always have them set to 1. If they are large shocks they will stiffen up the ride.
I also had a Rough Country lift kit and it was ROUGH ! I did install some I-Con progressive coil springs for the front and there was a big difference. Now I am running a 6" lift so we are a bit apart here. There is one other thing that I did that made a big difference in the ride and that was: I pulled down my spare tire and drilled two 4" holes in the sidewall and poured in 400 lbs. of concrete inside the tire. I hung it back under the frame and it softened the ride a bunch. Of coarse I now have no spare but with 38" tires it would do me no good anyways.

Another option out there for coil springs are made by TopGunz and they claim they are the best riding springs made. But they never replied to any of my e-mails so I opted not to try them.

Soft progressive coils
Small piston shocks
Oil rear spring packs so the slip on each other smoother.
Dump the air bags.

Try buying some bags of sand from Home Depot and place them in the very back of bed against tail gate and see how the ride changes with the different amounts of sand. There are ways to put weight in the rear of the frame besides sacrificing the spare tire.

Good luck with it, it can be improved my truck rides really nice now and it too was horrible.
One more thing, try dropping down the air pressure in the tires. I have my tires at 30 psi instead of 50 psi and it helped a lot.
Good Luck on the task............

Ok thanks.
I'll start by getting rid of the air bags and possibly looking into new springs and shocks

Been doing a little more research, and it looks like on carli's leveling kits they all come with carli's coils and then the difference is in the shocks that come with each kit. So does anyone have opinions on the best riding coil and shock combo? Feel like I might be able to do better than the $2500 for carli's kit with a little research. And on their website it states that the leveling kit has 9" of travel in the front which is much more than I have now, is this just do to my rough country leveling kit?

I had just some pucks on my 2010 also and just switched to icon 2.5" coils and 5160s all around with 4.5" traction block and 3 link from Trevor at PMF the ride has improved greatly IMO. Very happy with it.

Holy CRAP,

Yea you can do better by a long shot !!! I paid $385.00 for the I-Con springs which are made by Donaldson Racing. Of coarse you can go with another spring manufacturer I would look for a progressive rate coil to get the softer ride.
Soft shocks are going to make a big difference so choose wisely.

This is where I meant for the holy crap go to $2500.00 LIFT KIT, COME ON!!!

Sorry Montana6.0, I too have the I-Con springs and what a difference. Like how my springs have the Donaldson Racing name painted on the coils. That guy is in prison for child pornography and I-Con took over his springs from what I have read. LOL

If you want to start over on a kit for your truck. This is what I would go with.

Icon 4.5" kit and get the One Up Offroad ALA arms. They will tighten up your steering, give you an improved tighter turning radius over stock since they are offset, also adjustable for different lift heights and plenty of caster adjustments. I would leave your stock rear springs and if you want to go wild then swap them for an Icon replacement or deaver. I like the factory springs that way you still retain the towing capacity of the truck. Then I would add some One Up Offroad traction bars to the rear. They are setup so you can still offroad and have rear travel and your suspension can work the way it was designed. Then if you want the rear of the truck to ride level you can add air bags if you want.

Don't fill your spare tire with concrete either. Honestly I have driven my truck with a stock spare tire on the front when I was running 40's. It looked real funny but I was still able to drive it to a place to swap it out.

I would give Marty at Truck Toyz Performance a call and talk to him about options for your truck. He will give you some good advice even if you don't buy anything from him.

Holy Crap, what?? Our spring are $315 for our linear rate leveling springs that ride softer than stock spring. Progressive rate doesn't mean softer, it just means differentiating rates in the coil. 8"-9" of front travel really isn't enough to justify a variable rate, plus you risk coil chatter being an issue in the tight-wind/soft rate given the small diameter of the Ford springs and tendency to bow a softer spring.

The ride quality comes from a combination of custom tuning in the shocks and our coil rates. Each kit with differentiating shock packages will ride different. For a slightly better than stock ride, grab a 2.5" starter system (much cheaper than a pintop system) and that will maintain your ability to tow and soften the ride. Grabbing a set of 17" wheels for the 35" tires will help too.

We use radius arms as they maintain a ton of control and deflect well when they need to. We've tested every configuration here and converting to a dual pivot point (4-link) free's up the front end too much for our liking. The added articulation is at the cost of stability and control so we elect to maintain the radius arm setup and have yet to find a downside. Added articulation is great on a 3,000lb. jeep but we prefer the stability of the radius arm on these trucks as the 8,000lb. truck will deflect the bushing enough to articulate and maintains amazing control.

As for the airbags, add our add-a-pack (comes with all but the leveling kit) and new shocks and remove the airbags, if you're not using them, for a way better ride.

Our kit rides, as stated above vary with shock package choice. The starter kit rides slightly better than stock with more control and added wheel travel while the pintop is a ride quality and performance transformation. All kits include the same coils and hard parts so if you want to upgrade in the future from the starter to the pintops, a shock change is all that's required.

The capability of the pintop extends past the pavement as well. Check out this thread I made that i will continue to update throughout the next couple days. We went for some testing and tuning in Baja and I'm documenting the trip and R&D session.

Baja 500 - 2013

As for your leveling kit. The rough country spaces you upward but doesn't add any actual travel.
