There is a plethora of aftermarket companies who cater to these vehicles and with them being designed very simple; it's not all that difficult to install most of the parts on offer yourself if you have a basic knowledge of mechanical practices.</p><p></p><p>A great way to get your Jeep looking the part and also increase its capabilities off-road is to install a suspension lift. When it comes to lifts there are a few different ways you can go to achieve that lifted look. But not all lifts are created equal. One of the easiest ways to lift a vehicle is with a body lift. Essentially what you're doing with a body lift is adding a number of spacers in between the body and the frame. This just makes the vehicle look bigger and will some times allow you to run a bigger tire, but a body lift does nothing in the area of increasing your suspension capabilities. Another type of lift is a coil spacer lift. This kind of lift adds a spacer in between the coil spring and the spring perch. As you can imagine, this adds lift to the suspension, which allows you to clear some bigger tires, but just like the body lift, doesn't really do much in adding any increase in suspension capability. In order to add an increase in suspension capability, you need to go with a lift that at the least, change out the coil springs with some extended coil springs. Going this route will increase wheel travel and also, just like the others, allow you to clear bigger tires. This is where lifts can really get crazy, especially if you decide to go with longer control arms and other more extreme suspension add-ons.</p><p></p><p>Today we're going to go over how to install a basic coil spring lift kit. This specific lift kit is a <a href="https://www.amazon.com/dp/B07L5Z6ZHX/?tag=jkforum-20" target="_blank">Rough Country 2.5 inches Suspension Lift Kit</a>. When it comes to suspension lift kits, this is about as simple as it gets. It's a very simple install and very budget-friendly. It will allow you to clear bigger tires and also increase your ground clearance. It also has the options of purchasing it with shocks, which I highly recommend. Any time you increase or decrease your ride height, you definitely want to swap your shocks with units that will match that newer suspension height.</p><p></p><p>[ATTACH=full]113265[/ATTACH]</p><p>Figure 1.Typical 2.5" lift kit.</p><p></p><p>[ATTACH=full]113266[/ATTACH]</p><p></p><p><strong>Materials Needed</strong></p><ul> <li data-xf-list-type="ul">Millimeter sockets sizes 10mm-22mm</li> <li data-xf-list-type="ul">Ratchet</li> <li data-xf-list-type="ul">Air impact wrench (if available)</li> <li data-xf-list-type="ul">Millimeter wrenches sizes 10mm-19mm</li> <li data-xf-list-type="ul">6" extension</li> <li data-xf-list-type="ul">12" extension</li> <li data-xf-list-type="ul">Pry bar</li> </ul><p>This install will be broken down into two sections: front and rear.
