Synergy Springs

[stino]

Old part of the thread but out of curiosity, did y'all do the mode adjustment and still have the harsh ride? I am really looking into the Falcons.

Can't speak to the users you're referring to, but I have the 3" (on a 2 door) synergy coils and the 3.3 SP2s. I keep it on the softest setting pretty much any time I'm not bombing and bottoming out a little to much.

Its a great combination for me, very controlled, a bit firm but lots of suspension travel so none of its jarring.

I also have the JKS Flexconnect endlinks w the "trail springs" that take just a little bit of the "bite" out of bumps

Excuse me if this sounds like a stupid question. Currently I am running Teraflex 2.5 in lift on a 2020 JLUR with the .5 inch load level kit in the rear. I would be running it in the front but for some odd reason it didn't fit and TF was kind of crappy to me about it. Synergy advertising springs that are 2 inch and 3 inch lift intrigues me as mostly every other company advertises in half inch measurements. If anyone here has the knowledge to help me understand this what type of lift do you get in comparison to Teraflex 2.5 springs to synergy 3 inch springs?

Teraflex recently posted in a thread that their springs are 140/170
This would make a good sticky thread.

To help people make the best choice for what springs they need/want, this is the info we currently have on our springs.​

I have Synergy 2" coils in the front and 3" coils in the rear. I got EXACTLY 3" of lift front and rear.

It is within 1/16" of 3 inches of lift on all 4 corners.
This is exactly what I was hoping I'd get. I like the looks of the stock rake.

I did a lot of researching of photos online to try to get an idea what springs I needed to order. Synergy says you will get exactly what the advertised height is, if you have a fully loaded Rubicon and their springs retain the factory rake. In my research, I found neither of these statements to be the case. It seems that most manufacturers seem to lift the rear slightly less that the front and Synergy seems to be no different in that regard. Maybe because most people think they want to level their vehicle? Also, it seems to me that almost every lift gives you more than what's advertised. I get that. I wouldn't be happy if I bought 2" springs and only got 1". I could live with 3" though. (That's what she said.)

I measured the height before and after in the front by measuring from the top of the axle tube to the bottom edge of the upper spring pocket and in the rear by measuring from the bottom edge of the frame to the top edge of the rear bump stop pad.

I have a JLUR with the factory steel bumpers and also a Warn Zeon 10S winch and my spare tire/wheel weighs 104 lbs.

I got lucky the first time ordering because of my research and I am extremely happy with the end result. The springs are nice and soft just like I have read. I am just temporarily running Rancho RS5000X shocks until I figure out what I'm going to get. The shocks seem a little stiff for the springs, but it still rides nice enough for now, but I know it can be MUCH better. I'm almost 100% certain I am going to get some Fox 2.0 remote reservoirs from Accutune. Then down the road, maybe 2.5's with DSC, or maybe even internal bypass coilovers. Who knows, maybe the 2.0 RR's will be all I feel I need?

I don't know if any of this info helps, but hopefully it will help someone down the road who reads this in the future.

What shocks did you go with and at what length?
