      Too tall

      I have the JKU and these are advertised to add 3”. However it seems more like 4.5”. As a result I needed to make further adjustments with adjustable track bars and sway bar links. The roll center still seems out of whack. Also, I’m not sure I have the right shocks now. I bought the Fox shocks for a 3.5 lift but it seems like I really need the longer shocks. Really disappointed.

      New Springs

      Had 3” spacers on top of stock springs until I could afford new ones. WOW !! What a difference!! Even my Wife was impressed ! No more Top Heavy feel while cornering, and a much smoother ride, On and Off the pavement.

      Quality Springs!

      I bought the Synergy 3 inch rear lift springs for my JKU to get back the rake I lost from my original lift (different manufacturer). Synergy coils are designed to maintain the factory rake of the vehicle, which I like. No longer does my Jeep squat when loaded up for a trip. I also noticed that on road ride quality also improved over my last set of springs. Small bumps like cracks in the road are absorbed more gracefully and with less of a shudder from the Jeep. Washboard roads are also more comfortable now. There must be something to the dual rate hype because I've noticed absolutely no performance compromises off road. I gave these springs 4/5 for value because there are so many other springs out there for the same price. I do think these are among the best coils out there, though. I also gave a 4/5 for appearance because almost all coils are powdercoated black. I'll admit that I prefer the silver/grey of my old springs. However, the finish on these seems to be high quality and has held up very well to the past several months of snow, ice, salt, dirt, mud, and water. If you're looking for a comfortable rear coil that actually provides the same lift front and rear, I'd highly recommend these.

      Worth it

      I have the aluminum steering box still (got the run around from several dealerships that wouldn't replace it per the recall and TSB)...looked into this bracket and one other one. Went with synergy because I have their adjustable track bar and was impressed with that. This bracket fixed 90-95%% of the wander and play in the steering wheel. Highly recommend.

      Synergy Lower Shock Mount

      After relocating my rear upper shock mounts up 2” I also needed to move the lower rear shock mounts up 2”. The Synergy lower mounts allowed me to do that. Besides being a well known brand this kit is easy to install and allows plenty of flexibility depending on your preferences. I recommend.

      Synergy track bar stabilizer mount

      Pretty simple install and overall it seems like a pretty good product so far. My only concerns with it and we'll see how it goes, are The extra amount of torque and vibration now being put into that already questionable track bar bolt. The axle and frame side track bar bolts are prone to working loose and causing death wobble and to address that I did add some orange loctite to these threads. Another thing I think is worth noting is that because this bolt is horizontal, you kind of need to put the bracket on the tie. Rod end slightly horizontal as well so you don't have an extreme angle on this bolt. Depending on your suspension setup, this can cause clearance issues but if you have a skinnier track bar or a lift it should be fine. I have a steersmarts pro series track bar on mine and no lift and the stabilizer will touch the track bar at full right hand steering Lock. I had to throw a couple of washers on the steering stop bolt to limit the steering range. Overall though, it is a solid product and it's affordable and it gets the job done.

      Good cam bolts with large round washers

      The round washers on either side help to maintain the setting you want for caster. Much better than the typical oval shape which shift around a lot more easily.
