So, you're thinking about throwing a lift kit on your Jeep Grand Cherokee ZJ? Awesome! You're in for a treat. A lift kit can seriously transform your ZJ, both in terms of its looks and its off-road capabilities. But before you dive in, it's important to know what you're getting into. This guide will walk you through everything you need to know about lift kits for your ZJ, from the different types available to the installation process and everything in between.

Why Lift Your Jeep Grand Cherokee ZJ?

Before we get into the nitty-gritty, let's talk about why you might want to lift your ZJ in the first place. There are several compelling reasons, and they usually boil down to a combination of aesthetics and functionality. If you have a lifted Jeep Grand Cherokee ZJ, you know the importance and value of it. Here are the main benefits:

Enhanced Off-Road Capability

This is the big one for most ZJ owners. A lift kit increases your ground clearance, allowing you to tackle larger obstacles on the trail. It also improves your approach, departure, and breakover angles, which are crucial for navigating challenging terrain. With a lifted Jeep Grand Cherokee ZJ, you'll be able to crawl over rocks, ford streams, and generally go places that a stock ZJ simply can't. The added clearance minimizes the risk of scraping the undercarriage or getting hung up on obstacles. For off-road enthusiasts, a lift kit is often the first and most important modification.

Improved Aesthetics

Let's be honest, a lifted ZJ just looks cool. It gives your Jeep a more aggressive and commanding presence on the road. The added height and larger tires make your ZJ stand out from the crowd. If you're looking to give your Jeep a more personalized and rugged look, a lift kit is a great way to do it. Many owners appreciate the visual transformation, as it gives their ZJ a unique and customized appearance. The lifted stance also allows for larger, more aggressive tires, further enhancing the overall look.

Increased Tire Clearance

Larger tires not only look great, but they also provide better traction and floatation in off-road conditions. A lift kit creates the necessary space to run larger tires without rubbing or damaging your fenders. This is especially important if you plan on doing any serious off-roading. The ability to run larger tires provides a significant advantage in various terrains, including mud, sand, and snow. The increased contact patch improves grip and stability, allowing you to confidently tackle challenging trails. Choosing the right tire size in conjunction with your lift kit can greatly enhance your ZJ's performance.

Types of Lift Kits for Jeep Grand Cherokee ZJ

Okay, so you're sold on the idea of lifting your ZJ. Now, you need to choose the right type of lift kit. There are several options available, each with its own pros and cons. Here's a breakdown of the most common types:

Budget Boost (Spacer Lift)

This is the most affordable and simplest type of lift kit. It typically consists of polyurethane or aluminum spacers that are installed on top of your existing coil springs. Budget boosts provide a small lift, usually between 1.5 and 2 inches. They're a good option if you're on a tight budget and just want a little extra clearance for slightly larger tires. The installation is relatively straightforward and can often be done at home with basic tools. However, budget boosts don't improve ride quality and can actually make it worse if the spacers are too thick. They also don't address any worn-out suspension components, so if your ZJ's suspension is already tired, a budget boost might not be the best solution.

Coil Spring Lift

A coil spring lift replaces your factory coil springs with taller, heavier-duty springs. This provides a more significant lift, typically between 2 and 4 inches. Coil spring lifts offer improved ride quality and handling compared to budget boosts. They also allow for larger tires and better off-road performance. These kits often include longer shocks to accommodate the increased ride height. The installation is more involved than a budget boost, but it's still manageable for experienced DIYers. Coil spring lifts are a good all-around option for ZJ owners who want a balance of affordability, performance, and ride quality. They provide a noticeable improvement in both on-road and off-road capabilities.

Long Arm Lift

This is the most comprehensive and expensive type of lift kit. Long arm kits replace your factory control arms with longer, adjustable arms. This improves suspension articulation and allows for even greater lift heights, typically 4 inches or more. Long arm lifts offer the best possible off-road performance and ride quality. They also provide more control over your ZJ's suspension geometry, allowing you to fine-tune the handling to your liking. However, long arm kits are the most difficult to install, often requiring welding and fabrication skills. They're also the most expensive option. Long arm lifts are best suited for serious off-roaders who demand the ultimate in performance and are willing to invest the time and money to do it right. The improved articulation and control make a significant difference in challenging terrain.

Choosing the Right Lift Kit for Your Needs

So, how do you choose the right lift kit for your ZJ? Here are a few factors to consider:

Budget

This is the most obvious factor. Budget boosts are the cheapest, followed by coil spring lifts, and then long arm kits. Determine how much you're willing to spend before you start shopping.

Intended Use

How do you plan to use your ZJ? If you're primarily a street driver who occasionally hits a dirt road, a budget boost or coil spring lift might be sufficient. If you're a serious off-roader who tackles challenging trails, a long arm kit might be a better choice.

Tire Size

What size tires do you want to run? This will help determine how much lift you need. Generally, you'll need at least 2 inches of lift to clear 31-inch tires, and 3-4 inches of lift to clear 33-inch tires.

Installation Skills

How comfortable are you with working on your ZJ? Budget boosts are the easiest to install, followed by coil spring lifts, and then long arm kits. If you're not confident in your abilities, it's best to have a professional install the lift kit for you.

Installation: Doing It Yourself vs. Professional Installation

Speaking of installation, you have two options: do it yourself or have a professional do it. Each has its own advantages and disadvantages.

DIY Installation

  • Pros: Saves money, allows you to learn more about your ZJ, and gives you a sense of accomplishment.
  • Cons: Can be time-consuming, requires specialized tools, and can be dangerous if not done properly.

Professional Installation

  • Pros: Ensures the job is done correctly, saves you time and hassle, and provides peace of mind.
  • Cons: Can be expensive.

If you're a seasoned mechanic with plenty of experience working on Jeeps, you might be comfortable tackling the installation yourself. However, if you're a novice, it's best to leave it to the professionals. A botched lift kit installation can lead to serious safety issues and damage to your ZJ.

Things to Consider Before and After Lifting

Before you lift your ZJ, there are a few things you should keep in mind:

  • Driveline Angles: Lifting your ZJ can change your driveline angles, which can lead to vibrations and premature wear on your U-joints. To correct this, you might need to install a transfer case drop kit or adjustable control arms.
  • Brake Lines: Make sure your brake lines are long enough to accommodate the increased ride height. You might need to install longer brake lines to prevent them from being stretched or damaged.
  • Steering: Lifting your ZJ can affect your steering geometry. You might need to install a dropped pitman arm or adjustable track bar to correct this.

After you lift your ZJ, it's important to have it properly aligned. This will ensure that your tires wear evenly and that your ZJ handles properly. You should also check all of your suspension components regularly to make sure they're in good condition.
