Duff MS2020 shocks?

[the74bronco]

Has anyone ran the Duff MS2020 shocks? I was going to order Blistein 5100/7100 shocks, but I stumbled across them.

There was a pretty good write-up about Duff's new Eibach shocks on this site a couple weeks ago.

It's a monotube like Bilstein.
But they added more pressure and valved it for an eb. Tough to do better without custom valved Bilsteins, Fox or King.

Other than optional lengths to choose from, is the Eibach valving the same front and rear?

The recommended Bilstein set (5100s vehicle specific) for a Bronco lifted 2-3 inches has different valving front and rear.

Bilstein has 3-4 different valving options and various lengths to choose from. Their 5125s, 5165s and 7100s are for custom installs.

All around best is custom valved for your application. Raceshock.com can set you up with the valving you need based on what you have. Now its not cheap but well worth it. I bought used Bilstein 7100's from them valved to my specs and they were just over $200 each shock.

I had this exact question. I was looking at 360/80 blisteins for the front and the 255/70 for the rear.

Do you know what they are valved at? I was hoping someone had taken the plunge and to get some real world driving reviews.

This is great! Thank you! I kept searching ms2020 and could not find anything.

I'd have to look up part numbers to be 100% sure but I'm 95% sure that is the valving I am running right now. I have 3.5" deavers in the front and bronco graveyard deaver copys in the rear. It's pretty decent, I originally had the 255/70 in the front with some old junk doestch tech shocks in the rear, that was to light of valving for the front so I moved those to the rear and went with the 360/80 in the front. The front valving could stand to be slightly stiffer in compression for use at the dunes but the only way I think I can do that is with two lighter valved shocks at each wheel, I'd rather put the money I'd spend on 4 new shocks toward a set of coilovers.

That is a question for Monster Mike.

He indicated that the off the shelf Bilsteins that we buy are close but not perfect valving for our eb's. I think I have heard they (the off the shelf not custom valved Bilsteins) are a little soft for spirited off roading.
Unlike the off the shelf Bilsteins these off the shelf Eibachs were designed for an eb. I do not know the specific valving only that it is closer to what your typical eb owner wants. They kept the monotube design, increased the pressure and used a larger and stronger shaft.
For those of us that will not likely ever get custom valved shocks these are about as close as we will get.
I think they are about $120 bucks a piece.
As long as Bilsteins are $79 bucks and RS 9000's are $109 bucks a piece, I think these new Eibachs are "price pointed" perfectly.

I think I am going to order a set of Duff's. I will email and ask about valving. Not worried about the valving as I sit now, but once I get my bumper, winch and tires, I want to make sure I have the right setup.

Looks like these shocks are what we've been waiting for. Good job JD. I'm sure the other vendors will be following your lead. Again!
Now, if we could get real rear bumpers without the bumperette holes...
