My opinion is that 2 shocks in the rear is not adequate for a excursion. I think it's a reason the factory springs go saggy. I had one rear shock bracket get loose and the rear bounced 4 or 5 times going over bumps. Tightened it up and greatly improved the bouncing, but these excursions are super heavy in rear and need really good rear shocks or duals to preserve springs.
Maybe I will try blistin 5100 shocks to see if maybe they can handle it.
If you're off roading and feel the need for more shocks, you may want to call someone like fox and ask about a remote reservoir model or an adjustable one.
I'm not sure there is room to mount a remote reservoir so I'd ask for a long hose.
Which brings me to my next point. Where the heck would you mount dual shocks under an excursion?
An f250 kit will not work. The excursion uses bespoke upper mounts.
Seen a F350 at pick and pull. The rear shock mounts to axle same as excursion, but top mounts to frame on side. Maybe a second shock could mount there.
My opinion on rear shocks is based on how C code DRW springs reacted to one of my rear shocks being loose. It bounced all over the place. It's my opinion a stiffer shock or more shocks in rear would help springs last longer. I think if I were to remove both rear shocks the springs would wear out rather fast. Expecially since I have to go over speed bumps to get to work. Just an example...I would not do that.
A loose shock doesn't mean they're inadequate, it means that it wasn't able to do its job of dampening the spring movement... That or a blown shock will increase spring wear, but there's thousands of trucks rolling around with hundreds of thousands of miles on them with stock springs.
I also don't know how you'd mount the passenger side shock... Personally I have a diesel and 4" exhaust. The exhaust was a tight fit due to Excursions having a tank whereas the truck cousins have a substantially smaller spare. There's very little clearance between the shock, exhaust, and tank.
So what shock would provide the best spring dampening affect? I have the yellow blistin now. They work great up front, one bounce over speed bump. Rears bounce 2 times over speed bump.
Better springs and aftermarket shocks with adjustable or custom settings. Sway a way, Fox, king, etc.
The rear has stiffer springs and less weight so it's not gonna be the same... You can tell if a shock is working by how many bounces it takes over a speed bump.
The front weighs more, so if you're happy with the front with a single shock, you don't need two in the back.
Personally I run a single Bilstein 5100 on each corner and love them, not sure of the exact model number for my application but someone here should be able to chime in.
I run the 5100's myself. But these are all pretty inexpensive options compared to a real adjustable shock. If you're that picky I still recommend calling a shock company and getting their recommendation. Or call someone like Carli.
I think I will just get a set of air bags for the rear. That way I can adjust with psi instead of hoping a new shock will work.
Thoughts?
My thoughts, air bags and shocks don't do the same work.
Exactly what wheel are you trying to re-invent here? You started out talking about shocks and now suggest using air bags to adjust something, what?. The subject of EX rear springs has been pretty well discussed here and many of the various popular solutions have been documented here as well. What is the condition that you are hoping to adjust with either shocks or air bags, they both are great at what they do but they do different things.
