Shock me - Eibach or Bilstein?

Hey folks, after doing a lot of research, I am looking for some advice on shocks.

A bit about my setup: 3-1/2" lift, 35" tires, modified "half cab" top, front and rear steel bumpers with front winch. Front springs are Deaver from JBG. Rear springs are Superlift that I got lightly used from a local member of this forum. Rancho 5000 shocks, one at each corner.

I live only a couple miles from Forest Service/BLM, so I am rarely on pavement. The vast majority of use is <30 MPH on rough roads, think potholes, washboards, ruts and rocky 'cobblestone' type of terrain. No rock crawling or high-speed running.

It made a huge difference when I switched out the old Rancho coils and stock rear leaves and blocks with my current setup, but I've never really been completely satisfied with the ride. To be honest, I only had the Bronco out once or twice this summer because I don't enjoy it as much as I should.

Hitting the easy button means going with Bilsteins, which many have done with good results. However I think a lot of these applications are on street rigs, so not sure if directly comparable with how my rig is set up and what I do with it.

I had intended to go with RS9000s. I run them on my Superduty and they work well. The adjustability is nice for when I load my slide-in camper. But after reading reviews, apparently not too popular for the EB crowd especially considering the price.

The main feedback I am looking for are the relatively new MS2020 Eibach shocks from Duffs. I have not been able to find much real world experience with them. Does anyone run these shocks under similar conditions and able to report? Are they really worth the extra dough compared to the Bilsteins?

BTW - I am not considering running reservoir or custom tuned shocks on this rig. My price point is only within what the vendor's are offering off the shelf.

I have Wild Horses 3.5" rock crawler coils up front and their 11 pack leafs in the rear and Bilsteins. The ride is extremely nice on road and in the terrain you described. WH sells the shock sets but you can also check with Bilstein tech 858-386 5900. They were very helpful when I was figuring out my set up. I have never run Eibachs on the Bronco, but have them on my superduty and they ride nice. Good luck, but my vote is Belstein.

I found the valving which is key:

Front Valving 360/80
Rear Valving 255/70

I use single duff 70/30 up front to allow the front shock to easily compress and then really slow the rebound due to the front coils. i run ranch 9000 in the rear because they are leif springs and need a different type shock control. with varying strengths needed when loaded down for camping or towing. there the adjustability is nice to have. try running your trails with 15 to 20 psi in your tires and you will like your rides much better as the tires are doing most of the work. I have never had bilstiens or eibachs so I cant compare.

I do run aired down, normally 20 in the front and 15 in the rear in the summer. I run 6-8 psi in the winter which is really nice for ride smoothness and snow wheeling but not so much for handling. ;D

I will say spend the money on custom shocks. Call Lee at raceshock.com and he will get you set-up. You will never look back once you go that route. But be prepared to spend $200 a shock maybe more.

I'm running Duff 70/30s and I find them OK for driving around. However after being offroad for longer than a couple hours they fade away and become negligible.

I just purchased a set of bilsteins to replace them with over the Eibach. Would have like to have gone FOX 2.0 IFPs but I eventually plan to be on Coilovers.

I have had one set of Superlift leaf springs and they rode rough so your problem may not be entirely with the shocks.
I have a 76 with a 3.5" WH lift on 33s that rides great. It has a full top, no rear seat, stock bumpers and a factory spare tire carrier.

^^^^This has a lot to do with your ride quality. I replaced my stiff 2.5” rears with an 11 leaf set and it no longer rides like a garbage truck. I also run Bilsteins
( installed prior to the springs) and they work well both on and off road.

Yeah, I realize the rear springs are probably not ideal. At the time I was running stock springs with blocks and broke a leaf on the LR. A member nearby had the Superlifts that were the wrong height after he installed them, so I got those basically for shipping price, so it was a good deal at that time.

What shocks do you run?

Depending on the vintage the old superlift springs had a nickname of superstiff.

They did change with the times and came out with a line of soft ride springs. That is the newer stuff. Don't remember the time they changed, but a fairly long time ago.

These were new in 2013 or thereabouts.

They're made in Canada...isn't everything kinder and gentler up there? :-*

Rancho's are very old technology and for the cost of them now, you can get a better shock.
I tell 99% of people that a standard Bilstein shock will fit your need just perfect, but if you're saying your rig lives mostly off road, I would step up to a remote reservoir bilstein shock. Fox / King / etc are all great shocks as well, but bilstein has a more attractive price point.

Well since Duffs put the Eibachs on their Black Friday sale, I pulled the trigger. Someone there must have been reading this thread. :p
