Lots of good thoughts in this thread.....and others of course. I recently got a '19 SR5 and initially thought to get Kings. I paused and realized that while I'm sure awesome, I probably would never utilize all its performance. I'm looking/trying to decide between Bilstein 6112/5160 set up, Dobinson, or Eibach. They all seem good, just different. Dobinson being a twin tube vs monotube is the biggest difference/pause to me
I have been in a similar boat.
Initially I was thinking 6112/5160. I have only driven the stock Pro setup once and it handled great in town but the ride was very firm over small bumps. Generally, I have come to think that it is a case of if everyone says the sky is blue maybe it is actually blue (so good, not great).
I like the Eibach over 5100s as everyone reports a much smoother ride. But it is still a basic monotube shock. What gives me pause is their "Stage 1" lift. It is a 2.75 or so to 1" leveling kit. This is obviously for looks. I can use the shocks and the rear springs with Dobinsons front coils and I am sure it will be fine for me
EXCEPT
We drive a lot of miles in the desert. This is not about obstacles, it is about constant dips, washes, erosion, water channels, whatever. The suspension has to work hard or you have to go seriously slow over what is otherwise easy terrain. But what is easy to drive is not necessarily easy on the suspension. By contrast, a trail that may be harder to drive, with obstacles, may actually be just fine on the stock shocks.
And so, Dobinsons Monotube with no RR in the front and RR in the rear is what I currently favor.
If you dont offroad all that much, or not doing anything super rough, a $2000+ lift is a waste..
I agree that it is the distances and speeds (not necessarily racing speeds) that have us look into something better.
After speaking to Bilstein direct, a few shops and vendors, i think im going with a 6112/5100 set up with OME springs in the back.
The 90 day warranty of the Bilstein 5160 threw me for a loop, especially after numerous shops noted leaking issues and failures. Multiple shops also sides with Bilstein over Dobinsons but i personally think thats simply due to them not being as popular in America (yet).
The 6112 and 5100 have a limited lifetime warranty which is a bonus as well.
Thank you to those that shared their 2 cents.
But the million dollar question is if that's true for people who remember that the 5160 is a shock of 0-1" lift and not more. The warranty is an issue and I wonder if it has something to do with Billstein realizing that people will use the 5160 just as they do the 5100, meaning more lift.
I don't see the point of the 6112/5100. The rear needs the better shock if anything due to the ride being worse in the backseat in the first place.
All in all, tons of people fall for the aftermarket nonsense: you need this and you need that even for "mild" or "occasional" offroading. LOL. You need nothing for serious and frequent offroading other than tires. The stock setup will get the job done. The question is HOW. And the answer is, not comfortably enough in bigger rocks due to clearance limitations and not comfortably enough on faster desert terrain due to suspension limitations. But can it do it? Sure. There are very few trails that a lifted 5th gen will do that a stock Trail/TRD series one won't. The difference will be in the how, not where.
As for Dobinsons twin tubes, if they are fine in Australia, they are fine for me. I don't care if monotube is a newer design, it does not mean it is always better for a specific use. But I think I could justify capable monotubes due to how we actually use the 4R.
