So I am looking to install the Zone 6 inch lift kit on my wifes 2013 ram 1500 4x4 crew cab. Everyone I talk to says to go with the zone because of better warranty and parts. I know all about the ball joint issue that the 2013 and models seem to have if the front end geometry is out of wack, and I sure as hell don't want to install anything or combination that would be unsafe. So here is the question to current owners of 13 and up models. Is it safe to run the zone kit with the 5" coils in the rear and then incorporate the bilstein 5100's set at 2.1 on these particular models with no issues? If I need to run the 3 inch coils in the rear and use just zone front kit that is not an issue but of course we all like to go as high as possible haha. I will also be running mayhem rampage wheels 20x10 with -25 offset and atturo trail blade xt tires. Any help from current owners would be a huge help. Please also let me know how the ride quality is and how many miles you have on your rig.
