Hey guys, so you've got a classic 1999 Jeep Cherokee XJ, huh? Awesome! These things are legendary for a reason, and if you're looking to take your off-roading adventures to the next level or just want a tougher look, then a lift kit is definitely the way to go. But where do you even begin? Don't worry, I'm here to break down everything you need to know about getting the perfect lift kit for your XJ, from choosing the right height to understanding the different types and what you'll need to install it. Let's dive in!

Why Lift Your 1999 Jeep Cherokee XJ?

So, why bother lifting your trusty '99 XJ in the first place? Well, there are several compelling reasons. First and foremost, a lift kit dramatically increases your ground clearance. This means you can confidently tackle obstacles like rocks, logs, and deep ruts without scraping your undercarriage. It opens up a whole new world of off-road possibilities, allowing you to explore more challenging trails and terrain. Secondly, a lift kit provides better approach, departure, and breakover angles. This is crucial for navigating steep inclines and declines without getting stuck. It basically helps you to 'climb' over stuff easier. A lifted XJ just looks plain cool. It gives it a more aggressive, capable stance that turns heads. It's a statement. And hey, let's not forget the ability to run larger tires. Bigger tires mean even more ground clearance and improved traction, further enhancing your off-road capabilities. Finally, a lift kit can improve your overall ride quality. By upgrading your suspension components, you can often smooth out the ride, both on and off the road. It can absorb bumps and impacts more effectively, making for a more comfortable driving experience. So, whether you're a seasoned off-roader or just starting out, a lift kit can transform your XJ into a true adventure machine.

Types of Lift Kits for Your XJ

Alright, so you're sold on the idea of lifting your XJ, but now you're faced with a bunch of different options. Don't worry, it's not as confusing as it seems. Let's break down the main types of lift kits you'll encounter:

• Budget Boost: This is the most basic and affordable type of lift. It typically involves coil spring spacers for the front and add-a-leafs or shackles for the rear. Budget boosts provide a modest lift, usually around 1.5 to 2 inches. They're a good option if you're on a tight budget or just want a slight increase in ride height.
• Coil Spring Lift: This is the next step up. Coil spring lifts replace your existing coil springs with taller ones, providing more lift than a budget boost. They often include new shocks as well. Coil spring lifts are available in various heights, from around 2 to 6 inches, and offer a significant improvement in off-road performance.
• Long Arm Lift: This is a more advanced and comprehensive type of lift. Long arm kits replace your factory short control arms with longer arms that extend further down the chassis. This improves ride quality, articulation, and stability, especially at higher lift heights. Long arm kits are typically more expensive and require more extensive installation.
• Short Arm Lift: This is the most common type of lift. Short arm lifts include new coil springs, shocks, and often other components to lift your vehicle. They can be a great choice for those who want a quality lift without breaking the bank. These are a great entry point into the world of lifting your XJ. They are typically easier to install than long-arm kits, but they may not offer the same level of performance and ride quality.

Each type has its pros and cons, so consider your budget, intended use, and desired lift height when making your decision.

Choosing the Right Lift Height

One of the most crucial decisions you'll make is the lift height. This will determine how much ground clearance you gain and how your XJ will look and perform. Here's a general guide:

• 1.5-2 inches: This is a good starting point for mild off-roading and daily driving. It provides a noticeable increase in ground clearance and allows for slightly larger tires without extensive modifications. It's often the most practical choice for many XJ owners.
• 3-4 inches: This is a popular choice for more serious off-roading. It offers a significant increase in ground clearance and allows for larger tires. You'll likely need to make some modifications, such as trimming your fenders or installing extended bump stops.
• 5-6 inches: This is for those who want maximum off-road capability. It provides a massive increase in ground clearance and allows for the largest tires. However, you'll need to make significant modifications, including a slip yoke eliminator (SYE) kit, adjustable control arms, and potentially a new driveshaft.

Keep in mind that as you increase the lift height, you'll also increase the complexity of the installation and the potential for other issues, such as driveline vibrations or alignment problems. It's essential to balance your desired lift height with your budget, skill level, and intended use.

Essential Components of a Lift Kit

Okay, now let's talk about the key components that make up a typical lift kit. Understanding these parts will help you make an informed decision and ensure you get the right kit for your needs:

• Coil Springs: These are the primary component that provides lift in the front of your XJ. Taller coil springs replace your factory springs, raising the front end.
• Shocks: Shocks are essential for controlling the movement of your suspension. Lift kits include longer shocks to accommodate the increased ride height. Shocks play a vital role in ride quality and handling.
• Leaf Springs or Add-a-Leafs: In the rear, you'll either replace your leaf springs with taller ones or use add-a-leafs to gain lift. Add-a-leafs are extra leaf springs that you add to your existing leaf packs.
• Control Arms: Control arms connect your axles to the frame and control the movement of your suspension. At higher lift heights, you may need adjustable control arms to maintain proper alignment and caster.
• Track Bar: The track bar (also known as a panhard bar) helps to center the front axle under the vehicle. With a lift, you may need an adjustable track bar to recenter the axle. The track bar must be adjusted or replaced to match the new ride height.
• Bump Stops: Bump stops limit the upward travel of your suspension. With a lift, you'll likely need extended bump stops to prevent your tires from hitting your fenders. Ensure the bump stops match your lift height to prevent damage.
• Brake Line Extensions: Lifting your XJ stretches your brake lines. Brake line extensions or longer brake lines are often necessary to ensure proper braking performance.
• Sway Bar Links: The sway bar links connect the sway bar to the axles. They're often replaced with longer ones to maintain the sway bar's effectiveness.
• Other Optional Components: Depending on the lift height and kit, you may also need a slip yoke eliminator (SYE) kit, a new driveshaft, or other components to address driveline angles and vibrations.

Make sure to choose a kit that includes all the necessary components for your desired lift height and intended use. Don't cheap out on essential components, as this can affect your safety and performance.

Installation: DIY or Professional?

So, you've got your lift kit, and now it's time to install it. This is where you need to decide whether to tackle the job yourself or have it done professionally. Here's a breakdown of both options:

• DIY: If you're mechanically inclined, have the necessary tools, and are comfortable working on your XJ, then DIY is a great option. It can save you a significant amount of money and give you a better understanding of your vehicle. However, it requires time, patience, and attention to detail. Make sure you have a safe workspace and follow all instructions carefully. Watch videos, read forums, and don't be afraid to ask for help if you get stuck. Installing a lift kit is a rewarding experience, but don't rush the process.
• Professional Installation: If you're not comfortable working on your own vehicle or don't have the time or tools, then professional installation is the way to go. A professional mechanic will have the experience, expertise, and tools to install your lift kit correctly and efficiently. This will cost more but will save you time and ensure the job is done right. Make sure to choose a reputable shop with experience installing lift kits on XJs. Ask for references and read reviews to ensure they do quality work.
