Finding the right jeep zj lift kits can be a bit of a headache if you don't know exactly how much ground clearance you actually need. The ZJ—that classic 1993 to 1998 Grand Cherokee—is arguably one of the best platforms Jeep ever built. It's got solid axles front and rear, it's relatively comfortable, and it's got just enough luxury to keep your back from hurting on the way to the trail. But stock? It sits way too low. If you want to run anything bigger than a mall-crawler tire, you're gonna need to lift it.
The thing about the ZJ is that it uses a coil-spring-around-all-four-corners suspension. This makes it ride way better than the leaf-sprung XJ Cherokee of the same era, but it also makes lifting it a little more complex. You aren't just tossing a block under a leaf pack. You've got to think about spring rates, control arm angles, and how your axles are going to shift side-to-side once you move everything away from the frame.
The "Budget Boost" Entry Level
If you're just looking to get an extra two inches of clearance so you can fit some 31-inch tires, you're probably looking at a budget boost. These are the most basic jeep zj lift kits you can find. Usually, they just consist of polyurethane spacers that sit on top of your factory coil springs.
It's a cheap way to get the look you want without ruining the factory ride quality. Since you're keeping the stock springs, the "feel" of the Jeep stays mostly the same. However, you'll still want to look into new shocks. Stock shocks are barely long enough for factory height; once you add two inches of lift, they'll top out and ride like garbage over every speed bump. If you're on a super tight budget, you can get away with it for a while, but it's not ideal.
Stepping Up to 3 or 3.5 Inches
This is where things start to get interesting. A 3-inch lift is often considered the "sweet spot" for many ZJ owners. At this height, you can comfortably run 31s with zero rubbing, or 32s if you're willing to do a little bit of bumper trimming.
Most 3-inch jeep zj lift kits come with four new coil springs. This is a massive upgrade over the spacer lift because you can get a spring rate designed for off-road use. If you have a heavy steel bumper or a winch on the front, you'll definitely want those stiffer aftermarket springs so the front end doesn't sag.
At 3 inches, you're also crossing into the territory where you need to worry about your track bars. Because of how the suspension is designed, as the Jeep goes up, the axles get pulled to the side. If you don't use an adjustable track bar or a relocation bracket, your front axle will stick out further on the driver's side, and your rear will stick out on the passenger's side. It looks weird, and it can make the Jeep handle like a wet noodle on the highway.
Going Big with 4.5 Inches and Beyond
Once you start looking at jeep zj lift kits in the 4.5-inch to 6-inch range, you're basically building a dedicated trail rig. At this height, the geometry of the factory short arms becomes a problem. The control arms sit at such a steep angle that every time you hit a bump, the force is sent straight into the unibody instead of into the spring.
This is why most people at this height switch to a "long arm" kit. Long arm kits involve cutting off the factory control arm mounts and welding or bolting on new ones further back on the frame. It levels out the arms, restores the ride quality, and gives you insane amounts of wheel travel.
But be warned: this is not a driveway job for a beginner. You're going to be doing some serious work, and your bank account is going to feel it. You'll need extended brake lines, a dropped pitman arm (usually), adjustable track bars, and maybe even a Slip Yoke Eliminator (SYE) for the transfer case to prevent driveshaft vibrations.
The Components That Make or Break a Kit
When you're shopping around, don't just look at the price tag. Some jeep zj lift kits are cheap because they leave out the stuff you actually need to make the Jeep drivable.
Shocks are the biggest variable. Cheap white-body shocks will get the job done, but they tend to be very stiff. If you use your ZJ as a daily driver, it might be worth spending the extra cash on some nitrogen-charged monotube shocks. Your spine will thank you after an hour on the freeway.
Control arms are another big one. Many mid-tier kits come with fixed-length lower control arms. These are better than stock because they're stronger, but adjustable arms are the gold standard. They let you fine-tune your caster angle, which is the secret to making a lifted Jeep actually stay in its lane without you having to fight the steering wheel constantly.
Dealing With the Dreaded Death Wobble
You can't talk about jeep zj lift kits without mentioning death wobble. If you've never experienced it, count yourself lucky. It's a violent shaking of the front end that feels like the Jeep is trying to disassemble itself at 45 mph.
Lifting a ZJ doesn't cause death wobble, but it definitely exposes the weaknesses that lead to it. When you change the suspension angles, any tiny bit of play in your tie rod ends, ball joints, or track bar bushings gets amplified. Before you even think about installing a lift, go through your front end and replace anything that's worn out. A steering stabilizer is not a fix for death wobble—it's just a band-aid that hides the real problem until it gets worse.
Tires, Gearing, and the "Hidden" Costs
So you've picked out one of the many jeep zj lift kits available. Now you need tires. 31s look great on a 2-inch lift. 33s usually require at least 3.5 to 4 inches of lift and some trimming of the front bumper and the "pinch weld" inside the wheel well. If you want 35s, you're looking at a 6-inch lift or some serious fender cutting.
But remember, bigger tires are heavy. If you have the 4.0L straight-six engine, 33-inch tires are going to make the Jeep feel pretty sluggish. You might find yourself wanting to re-gear the axles to 4.10 or 4.56 to get that lost power back. If you have the 5.2L or 5.9L V8, you've got more torque to play with, but your fuel economy is still going to take a nosedive.
Is It Worth Doing Yourself?
Most basic jeep zj lift kits can be installed in a weekend with a decent set of jack stands, a floor jack, and some basic hand tools. The ZJ is pretty easy to work on, though the rear upper control arm bolts are famously annoying to reach.
The biggest hurdle for ZJ owners is usually rust. These Jeeps are getting old, and the bolts that hold the shocks and control arms tend to seize inside the metal sleeves. You're going to want to start soaking everything in penetrating oil a week before you plan to start the install. Also, buy a blowtorch. You'll probably need it.
In the end, lifting a ZJ is one of the most rewarding things you can do for the platform. It transforms the look from a "grocery getter" to a legitimate off-road machine. Just make sure you're buying a kit that matches how you actually plan to use the vehicle. If it's 90% highway and 10% fire roads, a 2-inch spacer lift is plenty. But if you're planning on hitting the rocks, do it right the first time with a solid 3.5-inch or long-arm setup. Your ZJ has plenty of life left in it—it just needs a little bit of a lift to see over the tall grass.
