      2 2015 Wrangler - GoodisonJeep Installation Time: Shop Install

      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.

      Synergy Springs

      Got the clearance I needed, the looks I wanted, and the ride is smooth and controllable. Great investment into our JK.

      Nice springs

      As advertised the provide the among if lift I was looking for even with the rock bumper and winch. I haven't yet had a chance to get them Offroad but I think it will be a huge improvement over the older ones.

    1 Top Rated Question

    I was wondering the spring rating on these springs. 645 or 900. My jeep has a lot of body roll in the springs. I want stiffer springs to help with the added weight of my front bumper and winches and stuff. It rides better with just me. if I go anywhere with the wife and kids in the jeep it is bad thanks.

    • Thank you for your question. The Synergy 2-Door 4.0 In./ 4-Door 3.0 In. Rear Lift Springs are multi-rate coil springs.
