  • Reliability and repair costs
  • Availability of parts and customization options
  • And more to help you decide which Jeep best fits your needs!

Let’s start with a brief background on each of these classic SUVs.

Brief Histories of the XJ and ZJ Models

The Jeep Cherokee XJ was introduced in 1984 as a more daily driver friendly version of the boxy, rugged Cherokee SJ model. It remained largely unchanged all the way up until its discontinuation in 2001.

The XJ Cherokee helped cement Jeep as a mainstream brand beyond just hardcore off-roading. It provided impressive capability combined with a more comfortable on-road driving experience.

The Jeep Grand Cherokee ZJ followed nearly a decade later in 1993, aiming to push Jeep further into the luxury SUV segment. It offered a sleeker, more modern and car-like design compared to past Jeeps.

The ZJ was discontinued in 1998 and replaced by the next generation WJ Grand Cherokee. But it still built upon Jeep’s reputation for combining ruggedness with more amenities and features.

Now let’s take a closer look at how these two iconic Jeep models compare across different categories.

Jeep XJ Overview and Background

The Jeep Cherokee XJ was introduced for the 1984 model year and remained in production through 2001, with only minor changes over its long production run. Here are some key details on the XJ Cherokee:

  • Body Style: Originally only available as a 2-door, a 4-door version was added in 1987. The boxy, slab-sided design provided excellent interior space utilization.
  • Engines: Early models had a 2.5L AMC 150 I4, later replaced by the 4.0L AMC Straight 6, renowned for its durability and performance.
  • Transmission: Standard 5-speed manual or optional 3-speed automatic.
  • Drivetrain: Part-time Command-Trac or full-time Selec-Trac 4WD systems. Solid front and rear axles for rugged off-road capability.
  • Suspension: Coil spring suspension all around, unlike the leaf springs on older Jeeps. This provided a smoother on-road ride.
  • Trim Levels: Base, Sport, Laredo, Limited and 60th Anniversary Edition. Offered an affordable range of options.

The XJ Cherokee was highly customizable and became popular in off-roading culture, with many owners modifying them with lift kits, larger tires, skid plates and more. Its simple, rugged design also makes it relatively easy to repair and maintain even today.

Jeep ZJ Overview and Background

As a response to the midsize SUV boom of the 1990s, Jeep introduced the Grand Cherokee ZJ for the 1993 model year. It appealed to buyers who wanted a more luxurious and car-like Jeep:

  • Body Style: Only offered as a 4-door with a rounded, aerodynamic exterior design. Less rugged than traditional boxy Jeeps.
  • Engines: Three engine options – the 4.0L AMC I6, 5.2L V8, and 5.9L V8. The V8 offered more power for towing and off-roading.
  • Transmission: 4-speed automatic standard across all models. No manual transmission option.
  • Drivetrain: Selec-Trac full-time 4WD or part-time Command-Trac 4WD. Coil spring suspension all around like the XJ.
  • Trim Levels: Base SE, Laredo, Limited. Higher trims offered more luxury features and styling.
  • Passenger/Cargo Room: More interior room than the XJ, with an optional 3rd row seat. Expansive rear cargo area.

The ZJ delivered more refinement and comfort for highway driving, though still retained solid off-road credentials. But this came at the cost of some simplicity and ruggedness.

How They Compare for Off-Roading Ability?

While both Jeeps offer respectable off-road capability, there are some key differences that give the XJ Cherokee an edge for serious off-road use:

  • Suspension Geometry: The XJ has better approach and departure angles, allowing it to clear steep obstacles without scraping its bumpers. The shorter wheelbase also improves breakover angle.
  • Ground Clearance: The ZJ offers up to 8.3 inches of ground clearance, vs. up to 8.6 inches for the XJ Cherokee depending on model year and suspension options.
  • Weight and Size: At 3,220 – 3,785 lbs, the XJ is lighter and more maneuverable than the ZJ which weighs 3,925 – 4,700 lbs. The 2-door XJ is especially nimble on tight trails.
  • Locking Differentials: The ZJ has no factory selectable lockers, while some XJ models came with locking differentials from the factory. Aftermarket lockers are readily available for both models however.
  • Engine Choices: The stout 4.0L AMC straight 6 could be found in most XJ models, while the ZJ offered more powerful yet more complex V8 options. For heavy off-road use, the simple and reliable AMC 6 is hard to beat.
  • Aftermarket Support: The XJ has a massive aftermarket selection of lift kits, armor, wheels, tires, etc catered specifically to off-road use. ZJ off-road parts exist but are less prevalent.

For difficult trails, rock crawling and other extreme off-road driving, the Cherokee XJ is better suited to handle abuse and modifications. But the Grand Cherokee ZJ is no slouch off-road either, offering great capability right from the factory.

How They Compare for On-Road Driving Dynamics?

As you’d expect from a more luxury-focused SUV, the Jeep Grand Cherokee ZJ shines as a comfortable daily driver:

  • Cargo and Passenger Room: The ZJ has over 10 cubic ft more cargo capacity, and roomier second and optional third row seating for up to 7 passengers.
  • Ride Comfort: With its coil spring suspension, longer wheelbase and unibody design, the ZJ generally delivers a smoother on-road ride quality. The XJ is more truck-like.
  • Luxury Features: Leather seats, power accessories, automatic climate control and an improved stereo system added everyday comfort. The spartan XJ interior doesn’t compare.
  • Handling: The ZJ uses a tighter turning radius and car-based chassis to feel more nimble around turns and on the highway. The XJ leans more in corners.
  • Engine Performance: The optional 5.2L and 5.9L V8s in the ZJ offer substantially more power and acceleration for merging and passing compared to the XJ’s 6-cylinder.
  • Safety Features: Dual front airbags, 3-point seatbelts and anti-lock brakes brought the ZJ up to modern safety standards of the ’90s. The XJ lagged behind in this area.

As an overall daily driver and family vehicle, the ZJ hits a nice balance between comfort and capability that the admittedly more outdated XJ can’t match. But it comes at the cost of higher complexity and repair costs.

Passenger and Cargo Capacity Comparison

On paper, the Jeep Grand Cherokee ZJ looks noticeably roomier:

  • Seating for up to 7 with optional 3rd row, compared to 5 seats maximum for the XJ.
  • Legroom is similar or slightly better in the ZJ, while front and rear headroom are increased noticeably.
  • Rear cargo capacity goes from 29.2 cubic ft for the XJ to 36.7 cubes for the ZJ with the second row up.
  • With the rear seats folded down, maximum cargo volume is 69.5 cubic ft for the XJ vs 79.7 cubic ft for the ZJ.

However, the boxy XJ can often feel nearly as roomy as its interior dimensions are maximized by its straight walls and slab sides. There’s also greater flexibility to haul especially long items due to the fold-flat second row.

So while by the numbers the ZJ offers noticeably more passenger and cargo room, clever packaging means the XJ isn’t far behind in usable space. Unless 7 seats or maximum cargo utility are needed, the XJ can work almost as well.

Reliability and Repair Costs

Both the Cherokee XJ and Grand Cherokee ZJ offer the durability and longevity expected from Jeep:

  • The rugged AMC 4.0 straight 6 engine used in most XJ and some ZJ models is known for reliability with proper maintenance. These engines can readily exceed 200k+ miles.
  • The XJ’s simplicity, lightweight body-on-frame design, and huge aftermarket for replacement parts makes DIY repairs very feasible.
  • Common problem areas for the XJ are cracked exhaust manifolds, rust in salt-heavy regions, and some minor electrical gremlins.
  • The ZJ’s more complex unibody design and greater reliance on electronics can make some repairs more challenging and costly. The lower intake manifold gasket is a notable weak point.
  • Issues with the ZJ V8 models include failed cylinder heads, radiator transmission cooler leaks, and evap leaks. Repairs tend to be pricier.
  • Front end suspension components like ball joints and steering linkages are prone to wear on both models after very high mileages.

In terms of longevity and DIY serviceability, the straightforward XJ Cherokee usually wins out. But properly maintained examples of both models can provide years of reliable service.

Aftermarket Support and Customization

A major advantage of the Jeep Cherokee XJ’s long production run is the enormous aftermarket for replacement and upgrade parts:

  • Everything from suspension, armor, wheels and tires to engine components and interior accessories is readily available from multiple manufacturers.
  • The XJ lends itself extremely well to lift kits, larger/aggressive tires, light bars and other off-road modifications. Its simple design makes customization more straightforward.
  • ZJ off-road modifications definitely exist, but far less variety is offered and some combinations may be harder to implement.
  • Want an XJ Cherokee on 37″ tires, with a 6″ lift kit, upgraded Dana 44 axles, custom bumpers, winch and onboard air? No problem! Doing the same with a ZJ is far less common.
  • The wider availability of interior parts also makes it easier to repair or upgrade worn out seats, switches and trim in the XJ. Used parts are also abundant in junkyards.

The Jeep aftermarket scene is centered around the Cherokee XJ. So if you plan to build a highly customized rig, the options are far greater compared to the ZJ.

Which Jeep Is Right for You?

So given everything we’ve compared between these two classic Jeep SUVs, which one is the better choice?

If your top priorities are serious off-roading, ease of modification, and maintaining costs down, the XJ Cherokee is likely the best option.

The Cherokee’s rugged simplicity, timeless styling, huge aftermarket support and proven reliability are ideal for the weekend wheeler or overland rig. Just be prepared for a relatively basic and noisy daily driving experience.

On the other hand, if you want a solid blend of off-road credibility with more on-road comforts and luxury, the ZJ Grand Cherokee deserves a look.

The additional passenger and cargo room, plush interior appointments, and choice of refined V8 engines make the ZJ a great compromise for a family that still wants Jeep’s heritage of capability. Just know repairs may be pricier down the line.

For serious rock crawling and high degree of customization, you can’t go wrong with a Cherokee XJ. But some buyers will appreciate the balance the Grand Cherokee ZJ offers instead. Be honest with your needs and you’ll know which of these Jeep legends is best for you!

In Summary

  • The Jeep Cherokee XJ prioritizes ruggedness and simplicity for easier off-road modifications, while the Grand Cherokee ZJ leans more towards luxury and comfort.
  • For off-road use, the XJ’s shorter length, better clearance, lighter weight and massive aftermarket support give it an edge.
  • As a daily driver and family vehicle, the ZJ offers greater interior room, more amenities and a smoother on-road ride.
  • Reliability and service costs tend to favor the simpler XJ, but both models can easily exceed 200k miles if properly maintained.
  • If you plan heavy customization or extreme terrain use, the immense aftermarket for the XJ is hard to beat.
  • Choose based on your priorities – overland rig or family hauler? – and either of these Jeep legends can make an excellent vehicle.

So there you have it – a detailed comparison overview of the iconic Jeep Cherokee XJ and Grand Cherokee ZJ SUVs. Hopefully this breakdown helps you pick the right classic Jeep for your needs. Happy wheeling!
