coil over suspension
if creating a coil over suspension like on the 05-06 superdutys eliminate the use of leaf springs? i usually never see a 99-04 superduty with coilover so i'm curious is to what is goign on with the use of these.
the reason why i'm asking is because my truck rides rough and any bump in the road makes my truck bounce somewhat and even on a straight road on cruise my truck seems to not take the bumps in the road smoothly so i'm thinking about switch shocks for now and then later going to a dual schock arrangement or even fabtech's coilover.

If you are thinking about doing Coilovers, then look at Full Traction, they have 6 and 8 inch systems. I'd love to have an 8 inch system. It lets you run of a tire as your fender will allow and still turn tight. There is no leaf springs to rub, and the way my truck is, it takes me at least a 40 acre field to turn it around. Do not confuse the stock 05+ front suspension as "coilover", as they are coil sprung, and have the shocks outside of the coil, behind the spring. A true "coil-over" spring has the shock inside the spring, like the Dirt Logic 4.0 from fabtech or the FT suspension. The only thing really holding people back is the cost of it. Way expensive.

Yeah, i've seen it done before on a Truck Toyz gallery. If you are interested in converting to coil springs, why not get a 4 link system instead of the inferior radius arm on the stock 05+ trucks? You'll need some custom bracketry, or a whole new super60 dana front axle out of a 05 + truck. Everything is different, including the riveted on upper mount that cages the spring and the shock mount. It's alot of work and a Rize 4 link system would be smarter.

I think (at least in the past) Skyjacker has a bolt on coil spring suspension.(edit... it's a z-link, I believe)
You would be very impressed with a good leaf spring suspension... if our not jumping and doing high speed desert chase truck stuff then you be happy with the Donahue Racing Deaver springs... they're about 400% nicer than stock.

The Skyjacker Z Link was reportedly a disaster. The Fabtech looks good. To be fair, I have not looked at Donahue's springs or Full Traction. I have the same problem. I am running a Skyjacker 4" lift and if I run over a quarter, I bang my head on the roof!

I'm not looking for a lift just a better ride. I checked the Donahoe Racing site for the "Deaver" springs but didn't see them. I just know my back end is very stiff. I may also try running about 5 psi less than the front. I just don't want to ruin a good set of tires doing it.

The Full Traction system is worthy of a look - especially with the 6" option. Instant Center Geometry feature will need to be investigated to figure out if this is just marketing. I did notice that the Full Traction Coil Over system uses DOM tubing and the FABTECH kit uses Chromium Malignium "chrome molly" solid rods

There is a product called Velvet Ride Shackles that replace the rear spring shackle. It pivots and allows a much softer ride, and when it's loaded down it expands fully and acts like a normal hard shackle. I have heard it compromises an inch or two of rear ride height. You may want to look into them.

We've done a few sets of the velvet rides, as noted you lose some height when loaded (and a little undoaded as well).
Donahoe doesn't sell seperate Deaver springs, Deaver makes all of Donahoes springs, and since Deaver is a bit harder to get that Donahoe you just but the DR kit.
