Thanks to Teraflex for getting this product out in perfect time for my 2015 Rubicon project!! I had already installed Teraflex 3"lift and long arm kits; then installed a Gobi rack and a Tepui tent: too much weight for my standard Teraflex shocks. Called and got a recommendation for these new Falcon Shocks... and managed to get in on some of the first shipped out.. what an incredible difference they made! Onroad handling is the best I have ever experienced in the two Jeep builds I have done: I mean, Awesome! Recently had to do a long drive with the addition of an inflatable boat, 9.9 outboard, fuel tanks etc onboard.... was amazed at the amount of sway control these shocks added: and I pushed it hard on a very windy back mountain road w/5mph turns... so much fun! As much as I have enjoyed Teraflex suspensions since 2001, I cannot find any reason to buy or change this set up now: its better than hoped for, dialed in to near perfection... Thanks again Teraflex! You Rock.. and I'm Rolling!!

I installed these on my 2010 4dr JK with a 3in lift already on jeep. They are off the hook. I had pro comp shocks on there before and they hit so hard. These shocks are way softer on the street , they are Exactly what i was looking for in a shock. Now the awesome part about these shocks are the handling. My jeep turns on a dime now they take away all the body roll when you turn sharp.This is the closet you are going to make your Jeep turn like a car. I am so happy with the way my jeep handles now it really is a night and day difference, I also did install the new 2.1 steering stabilizer I could not be more pleased with my purchase.
