On my 93, should the front leafs have a slight negative arch, or is that just sagging? It is a 4x4 and those are obviously some pretty beefy springs but I would do just about anything to improve the ride, even a little. If they are indeed sagging, seems to me this would 'eat up' what little working range these stiff springs had, like when they were new!

mine dont have a negitive arch on them but they are flat. Change the amount of air in your air shocks to change the ride.

I would, but I don't actually air shocks.:(

mine came stock with front air shocks, guess I was lucky. LOL:D

OE shocks were not air shocks. My springs did have a negative arch, and I know of 2 other dodges out there with negative arch, because they have sagged. This engine is really really heavy. Now you can see I have the skyjacker 2.5in lift springs ride is much better and they actually have positive arch. There is also about 3 more inches between the bump stop and spring now than there was before.

The plate in the door says that it has air shocks, it gives the amount of air to put in and everything.

wow, that must have been a very very special option, thats the only one i've ever heard of!

I was thinking of putting 2.5 skyjacker springs on the front. Figured it would about bring the front up even with the rear, or maybe a touch higher, which would be ok with me.
How much did you pay for the skyjacker fronts?

Front OEM air shocks..mmmmm;)

I got the set and new bushings, you have to use the skyjacker bushings, for like 350 I think maybe a little less. wasn't too bad.

I want and looked at the vin tag and I will correct my self, they were not stock. The sticker is above the vin tag.

Air shocks are pretty cheap. I have them all the way around on my Blazer. I run 25psi around town, and 135psi off road. It gives me just over 2" more clearance and takes the big bumps better without bottoming out as much.

I full set on the Cummins might be a good idea.:cool:

The air shocks were part of the Plow Prep Package. I would guess that is what your truck has, Mainer.

Mine is a plow truck, but doesnt have air shocks.

yeah but did it come from the dealer with a plow?

ummm, i dont think it did.

I put the skyjacker 2.5" springs on that I bought from summit racing and it did not quite level it out. I have heard of people using the 4" which more than levels it. Then they shim the rear, any of you out there? The ride is noticably better with the 2.5", good investment, but wish I had gone with the 4".

if you went with the 4" springs you would need to get a longer drive shaft and longer brake line, and possibly tie rod. When I got mine they accidently gave me the 4" instead of 2.5" and I didn't notice untill I went to put them on and I couldn't get the axle low enough, with the driveshaft still hooked up to get them into the spring mounts. So your looking at a lot more than just springs if you want 4" lift.

The ride is noticably better with these springs though. Mine rides a lot better than other trucks with stock springs.
