Is anyone running Synergy progressive springs? Actual lift heights?

[KG4NEL]

Hello!

I'm strongly considering a new set of springs this fall, as the ARB bumpers and Warn have taken a toll on my ride height - I'm down about an inch overall. As I'd like to go to 33x10s when I get new tires, I'm looking at a mild lift to get back what I lost, as well as gain a little over factory. The rig is a '12 JKUR, hardtop, IIRC already on the stiffest springs possible from Jeep (and with the Gobi going on next year, just going to get heavier).

Synergy's 1" progressive springs look perfect for this - no new bumpstops or end links required - but I'm wondering about real-world use. Did you actually get 1" of lift over stock out of them, and how heavily loaded? It seems like a lot of shocks are sized for either 0-1" or 1.5" and higher, so I'd hate to buy the smaller shock and end up with one that's too short for the application.

Thanks!

No experience with the synergy but I have a 17 jeep and added a lot of weight in the rear when I got it bumper, gobi rack, goose gear floor plate and cubbies and arb fridge. I lost about 2 inches of height. I added the rock krawler 1.5 inch triple rate coils and it brought the rear of my jeep back up to stock height maybe a tad higher. Hope that may give you some help. You can see what I did in my thread on here. Good luck.

I have those springs on a 2015 JKUR, LOD Bumpers and a UMV J30 top on stock tires. Note that only the front springs are progressive. The rear springs are linear.

After the top was installed I lost a little over an inch in height and the Synergy 1" rear spring raised the rear about 2" if I remember correctly. But after a while when fully loaded I still sag a bit and had to put airbags in them to level out the headlights when loaded. The rear bumper is full width with a swing out tire carrier, no gas cans or rack.

Up front all I have is the LOD midwidth bumper, no winch and the springs raised the front about 2 1/2", basically it leveled the Jeep. The top most coils are fully compressed and are basically acting as a puck so I am not sure what the point of a progressive spring is. Because of the height I had to change the swaybar links to maintain the correct angle for them. I should change out the rears but haven't gotten to them yet. Also I am still running stock shocks

When going over speed bumps I can feel the front body move to the left, it's a funny feeling and sometimes I can feel the rear move.

I have about 30,000 miles of them and they still ride good, I think the rears have softened up some from the daily weight. I drive a lot of washboard dirt roads and it's hard to tell how they do since the stock shocks aren't very good for that kind of road.

Would I do it again? Yes the improvement in handling was worth it. I'd also look at the 1 1/2" springs from Rock Krawler or Metal Cloak if you want to run 33" tires.

Edited it.

I am running the 1" springs on the '17, they netted me about 3" of lift. I have a light rig. It sits about 6'6" overall on 37s with a hardtop. The antenna hits the 6'8" parking garage warning sign.

I tried the 3" springs first and they were way to high. I tried the OME springs as well, they were more like the 3" synergy springs. What I like about the synergy springs is the rear springs are a constant shape and do not rub on the tank, while the OME springs have the egg shape'd spring. One day I will sell both the sets I tried but didn't like.

I also had the 2" springs on my old '11, also a light rig. Overall, IMHO, they net more lift than advertised. At least with my light rigs.
