Plushest riding Spring...

[shekmark]

I agree, tuned shocks are subjective, but I think a lot of it comes down to experience and what the goal is. For example, I'm sure Falcon achieved their goal when they released their shocks, but not everyone has been happy with them. They sacrificed some comfort for ride stability. Fox went a slightly different direction with their Fox IFP's and they are comfortable but lack some control.

My only comment on "clicker" shocks is they use flow restrictors to change the damping characteristics (The Fox DSC's use pre-loaded shims as well). Usually, these are very narrow bands of adjustment and while they will make the shock feel different, they are only adjusting a single aspect of the shock's performance, usually high-speed compression, when some of the most significant improvements can be found in adjusting rebound, low-speed compression, and the mid-speed stack.

Chris Steimle, This may seem like an odd question, but I'm gonna ask it anyway. Considering that Synergy and some other lift kits make the JLU springs stiffer to acommodate heavier payloads ( gear, steel bumpers, winches etc) , would it work to use JL 2 door springs on a JLUR if the JLUR was a light payload/gear vehicle ( 33-35 inch tires, no extra weight etc), or would they be too soft. Or are they the same and just lift the 2 door more?

Soft spring I could find are Synergy springs, especially the 1" coils. Will be installing these coils to soften up my stiff shocks (Teraflex Falcon)

As shown in the table posted, we use the same springs for 2-doors and 4-doors, they just get different lift heights due to the weight differences.

The only springs I don't recommend for 4-doors are our -10 springs. They will give you 1" of lift but still require 2" of bump stop spacing, so you will end up with less up-travel.

Can you please expand on this? Is the additional 2" of bump stop due to extra articulation, or some other reason I'm not considering?

The only company I've ever seen publish spring rates for all their coils is ARB/Old Man Emu. With all the others, it's a crapshoot.

So does Rock Krawler have their spring rates on their website?

Clayton and Synergy post rates. Synergy springs look pretty soft.

I bought the -10 springs, (for the super plushness) before he mentioned this. Guess I will find out the hard way. One thing I noticed is that the 1” springs offer the same amount of articulation as the 2” springs. (Both 12”). It means that the 1” springs are the same length as the 2”, but softer, so they will compress more (at ride height) but offer the same amount of droop.

So I guess that means at max articulation, you will still need the same bump stop requirement as the 2”. But you sit 1” lower than 2” at ride height. So you theoretically lose about 1” of actual articulation, so 11”.
Hey, I can live with that. Since my shocks does 9” at most.

The required bump stop spacing is to prevent the coil springs from going into coil bind. When getting more travel out of the springs, the block height increases.

@AllJumpStyle

You will have the same amount of travel/articulation with both since the extended/collapsed lengths are the same. The difference is in ride height. You will have 1" more up travel and 1" less down travel with the 2" spring than with the 1" spring.

Just wanted to pipe in and say thanks to @AllJumpStyle for answering questions and being super transparent about Synergy's product and design ethos. Much appreciated. I've learned some things just by reading this thread.

@AllJumpStyle , have you tested your springs on a 2-door Rubicon? Something doesn't seem quite right about the data in the spring table, or maybe I'm missing something or making some bad assumptions. The weight difference is about 400 lbs between a 2-door and 4-door Rubicon. Since weight distribution is almost 50/50, that's about 100 lbs per corner. The ride rate for your front springs is 120 lbs/in and the ride rate for your rear springs is 175 lbs/in, so that's about 0.83" difference in front and 0.57" difference in back. This is not 1" and the height difference front to back is not the same. This could be part of the problem @SpookyXJ had.

Spring takes about 2 weeks to arrive, but I will install and measure when they do. I have a feeling it will lift more than 1” but we’ll see.

You are making bad assumptions.

Late to the party on this thread.

Accutune Comfort springs with Fox 2.0 LSC Adjusters.

This is my latest set up. It's pretty plush. As close to stock ride as I have tried.

You are making bad assumptions.

@AllJumpStyle , care to clarify what I'm missing for everyone's benefit?

Did you take account of the initial spring rate?
