One of the best things about the Jeep Wrangler JK is its straightforward suspension system. With how straightforward it is, it’s one of the easiest to modify for off-road use. Not to mention, the modifications of the system are almost endless. However, if you are going to be installing a JK lift kit, there are a few things to note.
Jeep Wranglers come with fixed-length control arms. If you lift the Jeep without changing the control arms, the axles move towards the vehicle’s center. When installing any Jeep Wrangler JK lift kits, you want to switch to adjustable control arms, as they allow you to move the axles back out and help you fix any pinion angle issues. If you are going higher than four inches, it’s better to use eight adjustable control arms rather than just four.
Your cheaper lift kits use shocks that are manufactured for a variety of applications. Using these cheaper lift kits rather than a specialized JK lift kit causes your Jeep to handle more like a dump truck. Purchasing a lift kit made specifically for Jeep vehicles is the best choice because the shocks used in that kit are rated for a Jeep.
If you plan to lift your Jeep more than four inches, you want to invest in modified drive shafts. Doing this helps ensure that the universal joint angles are correct. Not modifying your driveshaft can result in damage to your differentials and your original driveshaft.
