They are slightly stiffer. They ride very well. I am pleased with them. I don't think you could go wrong with either. If MC made a 3" I would have bought them but they don't. I'm trying to keep this thing in my garage and was afraid the 3.5" would be too much. I've heard of people having issues with their mc coils but I never did. Thought they were great. I do prefer these synergy coils to the RK and teraflex I've had before. Certainly better than the RC I took out. I bet they will be very comparable to the mc once I get the bumpers, winch and 37" spare on it like I had with the mc.

Good to hear,how much lift did you actually get? I'm not trying to be too tall either.

mattgt5

right at about 3.5". Just a tip, if you want it level, but the 4" for the front. They are designed to keep the rake. I'm running a 1" spacer in the front because I didn't know. The mc 3.5" netted me 3.75" loaded down with armor and stuff.

Looks great! I run the synergy coils and love them. I am sure you'll feel the same. They're super long and I've been postponing putting new front bumpstops in because it was such a pain to get the coils in. Should be awesome on 37s.

That is exactly where I am now. Bout killed me getting them in and now I need to add a 3" puck on the perch. Have to have them since I'm doing a drag link flip.

I see an LS swap coming.

Same with my 2.5" Metal Cloak coils, 6 ton jacks nearly maxed out, axle almost on the ground, track bar disconnected, exhaust crossover skid bar unbolted since the driveshaft was hanging on it. Luckily with MC bump stops I can swap sizes without pulling the coil.

I'd still go 3" all around since only the 4 door 3" rear are progressive, the rest are linear. I originally wanted to go Synergy coils but that setup is a bit taller than I wanted.

Do you still have your blue JKU?

mattgt5

I had to do the same thing with the skid. When I called synergy, they told me all the sizes were progressive. My fronts are definately progressive. No I sold the blue one to another forum member who lives in Alabama. I think his wife drives it.

Synergy 4 door front 1"-3" coils are progressive, 4.5" and 6.0" are linear. Only the 4 door rear 3.0" is progressive, rest are linear. If you go with the front 4.5" and rear 3.0" to get rid of rake, you'd be running linear front, progressive rear. With 3.0" all around and 1" spacer in the front (the combo you're running), you're progressive all around. I'm a bit OCD so I'd have to have them match all progressive or all linear. I've read 0 complaints for any and all Synergy coil combos though.
