Hey guys, I have a 4.5 inch synergy long arm on my 2015 unlimited and it's incredible, I love it, but as many complain about the stance is definately leaning forward a bit. Who has leveled theirs out? Did you just go 3.5" springs in the rear or does that make the rear sag? Pics and advice much appreciated.

Like Teraflex & RK, Synergy retains the stock rake. It's intended to accommodate heavy rear bumpers, spare tires and cargo loads. You can adjust in a number of ways using spring spacers in front or shorter springs in the rear. Be sure you got the correct front & rear springs in the kit before you change anything.

It's all correct, I'm not disappointed by it I was expecting it, almost installed 3.5 in the rear from the beginning. I would rather not have to use spacers I want to try and just go straight to 3.5" in rear and call it a day just trying to get some pics

Synergy coils have rake built in unless you go 1" higher front or 1" lower rear (choosing coils)
I would just add spacers and be done.

Are you planning on adding a rear bumper / tire carrier? If so that'll likely level things out.

I already have a 10a rear bumper, an AEV carrier, and a 37" spare

???? My RK kit leveled my Jeep perfectly. The front fenders actually measure an inch higher than the rears, although the rock rails are level.

And I understand about accommodating for added rear loads, but what about accommodating for a heavy front bumper and winch?

Spacers get the job done, although Synergy claims they design their springs to compensate. I measured my 4" lift without the bumper & winch, then again after they were reinstalled. Difference was 5/16". Added an extra 1/2" of spacer (by swapping out the standard 1/2" with a 1") and called it good.
