Hello, I have a 16' Jeep Wrangler black bear edition which is currently stock but I'm currently looking into the Jks jspec 3.5 lift kit and putting some 35s on http://www.extremeterrain.com/jks-js...-jku-108k.html I've heard a lot of good things on this lift. I'm wondering if this kit includes everything I would need for me jeep and if there's any other additional parts I would have get and replace when adding this lift to my jeep. I also would like to know if any part of the jeep can be damaged by adding the 3.5" lift and or any handling issues?
How difficult is the instillation? Any welding or drilling need?
