I am looking to purchase some 2" front Skyjacker leaf springs from Summit, to fix the front end sag on my 93 W250. For those of you who installed the 2" Skyjacker front leaf springs, after a year or so of use, are the springs sagging at all? I would hate to install new leafs only to have them sag after a few years

 

Not sure exactly how long the ones I'm using have been there, just bought the truck in May or June, as I recall. But they are 2" Skyjackers and the PO said he put them on "last winter" which if true, would make them around a year old. Probably about right, because the bushings look new and the labels are or were mostly still there.

The driver's side did have some issue (sag?), sitting about a half inch lower than the passenger side. Overweight driver? Too many batteries? Dunno. Might have been that way to start with, for all I know. I just swapped the 1st big leaf and then swapped the entire pack side-to-side. Sits level now and they seem to be holding up just fine.

 

Broncobilly:

Have you considered changing the shocks before going to the trouble of changing springs? Pro-Comp makes an adjustable monotube and mine probably added an inch of lift even on the softest valve setting. (Monotubes contain nitrogen compressed to about 300psi that cause them to exhibit some spring-like behavior.) Pro-Comp doesn't list our first gen trucks in its applications list, but after multiple e-mails with their technicians, I determined that the MX6085 will fit the front of a W250 by simply removing the metal bushing inside the rubber bushing at both ends of the shock. Just an idea.

 

Great idea James 1, I think I may consider those shocks, maybe they will keep the springs woking more in the sweet spot rather than bottoming out?
I am on the fence with the Skyjackers...... Are the Skyjackers designed for the weight of our engines..... If not, they may be more prone to early sag??? (Speaking out of ignorance here as I haven't checked with Skyjacker)

 

All I can add to this is I ought the 1" lift ones and it sets just a fraction of an inch higher now than it did witht he origional ones. It rides a bit smother, but the rear bounces off the pavement on big bumps so it can only help so much

 

I've had mine about a year and a half now and haven't noticed any significant sag. I didn't take any hard measurements and write them down so its all relative really. My truck does ride much better than my dad's, which is stock.
I have stock shocks also that came with the truck when I got it. Might have to look into a set of those shocks.


I'm thinking about some timbrens for the front though, just to help out for the long run.

 

I've had mine on for quite some time now I guess 2 years or so at least close to 70,000 miles or so. I have a slide in camper that I use about 10 times a year too. The truck otherwise is loaded with a full toll box and 100 gallon fuel tank. The ride is much better than stock springs. I have not noticed any sag at all. The Softride springs have a special spring just for the diesel trucks make sure you order the correct one. I wish I had went with the 1 inch now since I am running smaller tires but I still like the look and ride. I have had the Rancho rs9000 shocks ever since I bought the truck and they are a very good shock. I ran them on my 94 for nearly 150k miles with great luck.

 

Did Skyjacker come out with a diesel specific front spring? There is a noted application that claims a 2" lift for a diesel. In reality, it is in fact a 4" spring for a gas application AND there is an unresolved issue with the spring eye bushing size. Gas truck applications and '91-earlier diesel have 1/2 inch spring eye bushings whereas 92 & 93 diesels have an upgraded FRONT spring eye bushing that takes a 5/8 inch bolt in the front and the original 1/2 in the rear. This has caused heated discussions in the past regarding the elimination of the steel sleeve from the bushing so the 5/8 bolt will fit the front spring eye. I am currently running a set of Skyjacker 2" front springs WITHOUT the steel sleeve in the front portion but I will be changing it. As soon as time and money permits, I am rearching the stock top spring leaf with the correct eye bushing sizes for my year and adding the lower packs of Skyjacker leaves. The front eye on the '92 & '93 diesels are rolled larger to accomodate the larger front bushing.

 

The first part of your statement is wrong, the 2inch lift springs for diesels is not the 4in spring for gas engines. 4 wheel parts accidentely gave me the 4in lift springs and when I tried to install with my driveshaft still hooked up and I couldn't drop the axle far enough to get the springs in. So I took them back and exchanged for the correct 2in springs specifically for a diesel. There are different part numbers for which amount of lift and for which engine. The 2in springs and the 4in springs have different amounts of static arch.

I don't know if they have rolled the ends larger so that you can use the steel sleeve insert. I don't remember any issues with installing my stock bolts. You can't use the factory spring bushings, you have to buy the skyjacker bushings, so maybe they came out with different bushings that are thinner to allow for use of the steel sleeve, and the 5/8" bolt.

 

My 2"ers have 5/8 front bolts and steel sleeves.

 

I'm pretty sure mine did also.

 

I have a 4 inch skyjaker lift 4 inch on front and 6 on the back eliminates the fac 2 inch blocks. They been on for a year now no problems yet and they were for diesel trucks. They also came with 2 diff sets of bushings with metal sleeves.

 

There is a seperate part # for the diesel springs at least there was when I ordered mine. I have the 5/8 bolt and steel sleeves.

 

Apwatson50,

Thanks for that info. I was told the aforementioned by a spring shop here in Hawaii. I bought my 2" Skyjacker front springs from 4 Wheel Parts here and the part numbers did indicate for a diesel application however, I could not use the steel sleeve for the front spring eye because the Skyjacker bushings are 1/2" all around and after calling Skyjacker, the tech told me to simply eliminate the sleeve so the 5/8 bolt will fit through. The guy at the local spring shop told me his son runs a similar shop on another island and specializes in rearching 4x4 springs and that's when he gave me the whole run down on the Skyjacker fronts for Dodges. We have had lengthy discussions on other forums regarding this issue. Is there a bushing for my application? 4 Wheel Parts told me the only bushings from Skyjacker for my application are the ones I currently have, which are 1/2 front and rear spring eyes. I wasn't too thrilled about removing bushing material so a 5/8 sleeve would fit. Any part numbers available?

 

That can't be right. The person you spoke to at Skyjacker either didn't understand what you were asking or didn't know what they were talking about.
