I'm thinking the springs will soften up, with more miles and with some crawling.
Shackle angles and length have a huge impact on suspension feel. How do they compare between two Jeeps?
That is what he is hoping, but the springs are going to have to soften up quite a bit for the rear shackles to tip out.
That's the difference I am talking about. I was able to build in some shackle angle and room for an increase in shackle length if necessary. The Rocky Road shackles are 3.5" on center. After 10 months, the rear's are still pointing forward and the fronts are about straight up and down. Hopefully the upcoming rubicon trip will help. If not we will be moving his mounts to the same measurements as mine.
Did he go with the 3-3.5" heavy or the 4-4.5" heavy? In your opinion, would the medium have gotten what he was looking for? Which springs do you have on yours?
And, did you get it up on the trails yet?
It just ran the Rubicon (in mostly 2 wheel drive from what I here). Look at this thread
Steve went with the 3-3.5" heavy which uses the CSO36R springs.
On my jeep I bought the CSO36R springs, ruff stuff brackets and assembled the suspension myself. The only suspension issue I had on the trip was my front shackles inverting when hitting the front shackles on rocks, driving the spring backwards. I will weld a cross bar into the shackles to prevent this. 33" tires would have helped too.
Steve had to drive very aggressive after breaking his front drive shaft. Getting towed up the hills ripped off 1 rear shock mount, bending 1 front shock shaft into a banana shape and putting a dent so big in the other front that it was basically not functional.... He pretty much finished the trip on 1 rear shock. It took a lot of momentum for Jonah to tug him up the hills.
Just my thoughts...guessing Steve's suspension/spring stiffness is fine. Would focus more on positioning the spring eye mounts on the frame to get the shackle to help flex. I know Steve kept talking about shock position as well, but I would guess that is secondary to getting the spring and shackle geometry correct. As the Rubicon showed on your jeep, those springs will flex a ton, especially with the shock mount extension. When you guys get this set up dialed, its gonna be unbelievable.
One last question, with the 3-3.5" would there be sufficient clearance for 35" tires?
Steve is running 33’s and he has the 3” kit. 33’s are the perfect size with his height.
If your putting this on your new 6 I would assume that it’s going to end up heavier than a 5 so with the spring sag the 4” is probably needed for 35’s.
Personally if I were going to go with 35’s I’d go spring over and flat springs; but I don’t want to encourage you to get too deep into this and not be ready to go to the rubicon next year with us.
I am really, not a SOA guy. I don't want to run 35's but, the Sierra Trek requires 35" or better, much to my dismay. The 34" I have now I like.
And, that is my plan, to be Rubi Ready next year!!!!
I think with the 20 extra inches on a 6, 35s would be nice. Probably comparable to the 5s with 33s?
