    Video Review & Installation

    I'm Ryan from extremeterrain.com and this is my review of the Rough Country three-and-a-half inch Series II lift kit with shocks. This kit is available for all 2007 to 2016 JKs, and there is a version for both the two-door and the four-door. Make sure you get the one that's right for your Wrangler. I recommend this lift kit for anyone who wants to run a 35-inch tire on their JK and doesn't want to break the bank with the lift kit. I like this kit because it's really complete. It has everything that you would need to get the Jeep lifted and back on the road again. It is actually pretty unique because it includes some components that aren't included in other lift kits of the same height.The two main components in a lift kit of this size are of course the springs and the shocks. The springs that are included in this lift will provide three-and-a-half inches of lift to clear 35 inch tires or even bigger depending on your driving situation. The shocks that are included are Rough Country's N2.0 nitrogen charged shocks, which should provide a more comfortable ride than the Performance 2.2s. Also included in this lift and most others of this size are a few other components. Rough Country includes new rear sway bar and links, which are of course longer for the lift. They have you move the factory rear sway bar and links to the front. Again, they're longer and they work better for these lifted springs. They also include bump stops for both the front and the rear, a rear track bar bracket, and brake line relocation brackets for both the front and rear of the Jeep. This lift kit does include some components that aren't included in all other three-and-a-half inch lift kits on the market. Any time you're lifting three-and-a-half inches or more, I always recommend that you do some caster angle and pinion angle correction on the front of the vehicle. The caster will keep you from having that flighty feel on the highway, and the pinion will ensure that you don't have any drive line vibrations in the front of the Jeep. There are a few different ways to accomplish caster and pinion angle correction on your Jeep. One of those being cam bolts, another would be geometry correction brackets, and finally completely replacing the control arms. This kit includes new front lower control arms that are going to give you back both caster and pinion angle. Now these control arms do have a factory style rubber joint on both ends instead of a spherical joint, so you're not going to gain a lot of articulation or movement off road. If that's a concern of yours, you can always upgrade to different control arms down the line. Another component that's included in this kit that's not included in all other kits on the market are these rear coil correction plates. Anytime you're lifting three-and-a-half inches or more without adding new rear control arms to the Jeep, you're going to get a little bit of a bow to the spring. These plates will help to straighten out the spring and make sure that you get a full three and a half inches of lift. The last components that are included in this kit that aren't included in every other kit on the market are this front track bar relocation bracket and drop Pitman arm. If you plan on running those two parts, there's a little bit more information that you should know. Bump steer is caused by having your drag link and track bar out of parallel. It'll show up when you're driving down the highway and you hit a dip or a pothole on the road, and your steering wheel turns all by itself. Running both of these components together will ensure that your drag link and track bar stay parallel and eliminate any chance of having bump steer. A lot of people, myself included, prefer not to run a drop Pitman arm. The drop Pitman arm provides additional leverage in the steering system, which can cause additional steering wheel feedback and wear and tear on steering components. If you decide to run the front track bar relocation bracket included in the kit but you don't want to run the drop Pitman arm, another way to get the drag link and track bar back into parallel is by raising the axle side of the drag link. This can be accomplished with the drag link flip kit available on the website. The installation for this lift kit is going to be similar to most other lift kit installs, but it's a little bit more involved because of some of the additional brackets and hardware that are included in this kit. To get this lift kit installed, you'll have to first support the Jeep from the frame and remove or disconnect everything that keeps the axles from completely drooping. That includes the track bars, sway bar links, brake lines and emergency brake lines, drive shafts and shocks. Once the axles are allowed to completely droop, you can pop out the old springs and shocks and put everything back together with the new components. There is some drilling involved in the installation of the front track bar bracket and the front bump stop extensions. Other than a drill, the only tools you'll need are a regular socket set and wrenches. The whole install should take about six hours, and while there aren't any specialty tools necessary, if you do have access to a lift or air tools, it'll definitely speed things up. If you have an older Jeep that has some rust, you might want to keep your penetrating spray or heat handy to help with those stubborn bolts. Rough Country is known to provide affordable parts and lift kits for your vehicle. While this is one of the less expensive lifts on the website, the components that are included are high quality. It actually has a lot of components that aren't included in other lift kits of the same size. I would say with this lift kit, you get a lot for your money. If you want to run 35 inch tires on your Jeep and you're looking for a complete lift kit at an affordable price, this would give you the lift height you're after and some additional components to correct suspension geometry that aren't included in every other lift kit on the market. That's my review of the Rough Country three-and-a-half inch Series II lift kit with shocks fitting all 2007 to 2016 JKs that you can find right here at extremeterrain.com.
