Hi Everyone,
I very pleased to see that this post still "has legs". Occasionally, I'll get a PM from one of you asking for details. I would love to help but at this point I haven't owned that particular Explorer (or any Explorer for that matter) for six years. I simply don't recall much of what I did anymore (old and feeble now...). I apologize.
What I do suggest is to re-read my original post and then read all of the Comments that came thereafter. There are some follow-up posts, from me, as well as some posts from others that either did the swap or did research regarding the swap. As Silver X recently posted, he sourced leaf packs directly from Eaton Detroit Spring (instead of scouring junk yards). That worked out great for him. I would hope EDS is still willing to help out but they may not be "into" it anymore. You will have to check with them.
As I mentioned in my original post, I believe the F150 leaves that I used came from a late 80's truck. What's more important is the width of the leaves and the load rating of the spring packs. You can easily measure the leaf width. Load data should be available on the VIN sticker in the driver's side door jamb.
I have seen local Explorers with a suspension lift as well as shackles. In my research, I determined that shackles only
add to the instability that's already inherent in the rear suspension (remember the Firestone tire fiasco?). Adding the F150 leaf pack gives you lift AND stability. If you need more lift, contact a leaf spring supplier regarding custom arched leaves. I know that's not cheap but it's better than the distinct possibility of flipping over due to shackles.
This is my opinion and I'm not here to start a flame war. I don't frequent these forums anymore so replying with a rant, aimed at me, won't have much effect. If you choose to install shackles, that's your choice. I'm not suggesting you're an idiot for doing so. All I'm saying is that, in my opinion, it's not the right way to gain lift. Off my soap box now.
I originally posted to help other "cheap a$$ bastids" get some suspension lift while curing the instability. I still enjoy "junkyarding" very much and thought this was a fun/cheap way to get more out of my (ex) Ex. As you can see, there's quite a bit of physics and engineering in suspension systems. I'm not an engineer. I do have access to two; my brother-in-law (a PE in Colorado) and my best friend (an ME with a Masters degree in Massachusetts). Both are enthusiasts and know of which they speak. They also provide the same responses when I ask them questions (in other words, they confirm each other with respect to engineering data/questions). So, while I've really only "scratched the surface" there is some validity to what's been presented here. However, you're on your own when it comes to what you choose to do to your own vehicle. If you have any question about any of this, I would suggest you contact a profession engineer or not make the modification. Just because a bunch of us have done this modification, and had success, doesn't mean we're not crazy....
To those who choose to make the mod, I hope it works as well, for you, as it did for me. Cheers - Dave.
