Suggestions on Progressive front shocks needed

Looking for a set of Progressive front shocks. Adjustable would be good, but not necessary.

Can either be just shocks and I'll pick out my own coils are assembled coilovers.

I read about every manufacturers website and almost none make it clear which models are Progressive and which are Digressive.

Not looking to spend a couple thousand on Kings. I picked up a jeep to a use off-road so this one won't be seeing as many trails as before

Thanks!

 

AFAIK, Not a single shock manufacturer publishes a damping curve or any other metrics. I think you need to get tunable shocks and get them tuned if you want to know anything. And my experience is doesn’t matter whatsoever for a daily driver.

 

2" Bilstein 5100 for the win. Bilstein recommends you keep the oem coils....

 

5100's are digressive

 

Aren't Eibach Progressive? it's the only ones that I've found so far on a quick search.

Also, @jboudreaux1965 , why do you want progressive? Digressive is usually better on the street as it gives a stiffer ride/less body roll.

 

What are you basing that fact on?

 

Bilstein says so on their own website. Don't think there is any question on that.

 

The above snip was for the 5100, here's a snip for the 6112.

 

Agree Bilstein is known for digressive valving.

 

And here is the 4600, too.

 

That sounds like sales/marketing language which might or not mean anything in an engineering sense.

Have you seen the patent?

 

I suspect you guys reading too much into sales/marketing mumbo jumbo.

 

Well, as someone who works with a manufacturing and design engineer whose last job was working at Bilstein... he says digressive means digressive.

 

He says digressive is a description, not a marketing feature. lol.

 

Ok, but as an engineer myself, if it isn’t defined quantitatively it means little or nothing to me.

 

Digressive, linear, or progressive are different valving types though. The OP doesn't want digressive. That rules out off the shelf Tacoma Bilstein shocks.

 

If you or your engineer friend could send me a quantitative description of those terms specific to a set of real world shocks (eg a graph of the damping force as a function of shock velocity), I would find it interesting. I’ve never seen any published data on popular shock absorbers.

 

Not that I was involved in this but I read a thing or two. This might help- https://accutuneoffroad.com/article...OUajV4nMsoKSsl15FWB9aT-dCBivXm_SKPvHVl253a5To

 

Dobinsons MRA are 3 way adjustable and said by @Crikeymike (in another forum but probably in TW somewhere) to be progressive valved.

 

I understand the concepts surrounding shock absorbers. What I don’t know of is quantitative information on the actual performance of shock absorbers sold on the market.
