The TJ Generation: A Pivotal Leap for the Wrangler

The Jeep Wrangler TJ, introduced in 1997, marked a significant departure from its YJ predecessor while simultaneously paying homage to the classic CJ Jeeps. The most notable and celebrated change was the return of the iconic round headlights, a beloved feature absent from the square-headlight YJ. However, the true revolution lay beneath the surface: the TJ abandoned the YJ’s leaf spring suspension in favor of a modern coil spring setup on all four corners. This was a game-changer, dramatically improving ride quality on paved roads, enhancing articulation for superior off-road capability, and offering a smoother, more controlled driving experience.

The 1998 model year falls squarely in the early-to-mid period of the TJ’s production run (1997-2006), benefiting from the initial design improvements while preceding some of the later, more complex electronic additions. It retained the simplicity and robustness that Jeep enthusiasts cherished, making it a highly desirable vintage. Its compact two-door configuration, removable doors, fold-down windshield, and various soft and hard top options cemented its reputation as the quintessential open-air adventure vehicle. The TJ’s design philosophy was clear: build a vehicle that could tackle the toughest trails with ease, yet still be enjoyable enough for daily commutes, embodying the spirit of freedom and exploration that defines the Jeep brand.

Under the Hood: Engine and Drivetrain Options

The 1998 Jeep Wrangler 2 Door offered a choice of two robust engines, each with its own characteristics, paired with reliable transmission and transfer case options.

Engines:

• 2.5L AMC Inline-4 (I4): This standard engine produced approximately 120 horsepower and 140 lb-ft of torque. Known for its simplicity, reliability, and ease of maintenance, the 2.5L is a capable engine for light off-roading and general use, particularly if not burdened by heavy modifications or large tires. It’s often praised for its ability to crawl slowly over obstacles without stalling, but it can feel underpowered on highways, especially when climbing grades or fully loaded.



• 4.0L AMC Inline-6 (I6): The undisputed king of TJ engines, this legendary powerplant delivered around 181 horsepower and a robust 222 lb-ft of torque. The 4.0L is celebrated for its incredible durability, ample low-end torque (perfect for off-roading), and overall performance. It’s widely considered one of the most reliable and long-lasting engines ever produced by Jeep, making it the preferred choice for most enthusiasts and those planning significant modifications or serious off-road excursions.

Transmissions:

• Manual: A 5-speed manual transmission was available for both engines: the Aisin AX-5 for the 2.5L and the heavier-duty Aisin AX-15 for the 4.0L. Both are known for their ruggedness and direct control.



• Automatic: A 3-speed automatic transmission was an option: the 30RH for the 2.5L and the more robust 32RH for the 4.0L. While lacking the modern efficiency of more gears, these automatics are incredibly durable and simple, making them popular for rock crawling due to their smooth power delivery.

Transfer Cases:

• NP231 Command-Trac: Standard on most Wranglers, this part-time transfer case offers 2WD high, 4WD high, and 4WD low. It’s a proven, reliable unit, ideal for most off-road scenarios.



• NP242 Selec-Trac: Less common on the 2-door TJ but occasionally found, this full-time transfer case adds a "Full-Time 4WD" option, allowing the vehicle to be driven on pavement in 4WD without driveline binding, making it more versatile for varied weather conditions.

Axles:

• Front: Dana 30 (standard for all TJs).
• Rear: Dana 35 (standard for most TJs). The Dana 35 is adequate for stock applications but can be a weak point under heavy off-road abuse or with larger tires. A highly sought-after upgrade was the Dana 44 rear axle, which was optional on some Sport and Sahara models and is significantly stronger, making it a major selling point for any used 1998 TJ.

Beyond the Pavement: Off-Road Prowess and Capabilities

The 1998 Jeep Wrangler 2 Door TJ was engineered from the ground up for off-road dominance, a reputation it effortlessly lives up to. Its combination of a short wheelbase, high ground clearance, solid axles, and exceptional approach, departure, and breakover angles makes it incredibly agile and capable on challenging terrain.

Key Off-Road Advantages:

• Coil Spring Suspension: This was the TJ’s defining feature. It allowed for significantly greater wheel articulation compared to leaf springs, keeping tires in contact with the ground over uneven terrain and improving traction. The coil springs also provided a more compliant ride, absorbing bumps and impacts more effectively, reducing driver fatigue on long trails.
• Solid Axles: Both front and rear solid axles contribute to the Wrangler’s ruggedness and predictable handling in off-road conditions, allowing for maximum articulation and durability under stress.
• Compact Dimensions: The 2-door’s short wheelbase makes it highly maneuverable in tight spaces, allowing it to navigate narrow trails, switchbacks, and crowded rock gardens with ease.
• Low Range Gearing: The NP231 transfer case’s 2.72:1 low range ratio, combined with appropriate axle gearing, provides immense torque multiplication, allowing the TJ to crawl slowly and powerfully over obstacles without relying on momentum.

Practical Off-Road Advice for TJ Owners:

• Tire Pressure: Airing down tires (to 10-15 PSI, depending on terrain and tire size) dramatically increases traction, improves ride comfort, and reduces the risk of punctures off-road.
• Choose Your Line: Before tackling an obstacle, visually scout the best path, considering tire placement, ground clearance, and potential hazards.
• Use 4WD Low: For serious off-roading, engage 4WD Low. This provides maximum torque and control, reducing strain on the drivetrain and improving safety.
• Spotting: When possible, have a spotter guide you through difficult sections. Their external perspective can prevent costly damage.
• Recovery Gear: Always carry essential recovery gear: a tow strap, shackles, a shovel, and ideally a winch or a Hi-Lift jack. Never venture off-road alone.

The Modder’s Dream: Customization and Upgrades

The 1998 Jeep Wrangler TJ is arguably one of the most customizable vehicles ever made, earning it the moniker "the Modder’s Dream." Its relatively simple mechanical design, vast aftermarket support, and a passionate community make it an ideal platform for personalization and performance enhancement.

Common Upgrades and Considerations:

• Lift Kits: The most common modification, lift kits increase ground clearance and allow for larger tires. Options range from simple budget boosts (spacer lifts) to comprehensive suspension lifts (short arm, long arm).
  • Considerations: Lifting requires careful attention to driveline angles, steering geometry, and brake line extensions. A 2-3 inch lift is generally achievable without major modifications, while higher lifts require more extensive changes (e.g., slip yoke eliminator, CV driveshaft).
• Larger Tires: Crucial for off-road performance, larger tires improve ground clearance and traction.
  • Considerations: Larger tires put more strain on axles, steering components, and the engine. Re-gearing the axles is often necessary to restore power and drivability, especially with the 2.5L engine or tires over 33 inches.
• Bumpers and Armor: Aftermarket steel bumpers offer better protection, recovery points, and winch mounting options. Skid plates protect vital underbody components.
• Winches: An essential recovery tool for serious off-roaders.
• Lighting: Auxiliary LED light bars and spotlights improve visibility on trails.
• Axle Upgrades: For heavy off-roading with larger tires, upgrading the Dana 35 rear axle to a Dana 44 or even a stronger aftermarket axle is a common and highly recommended modification. Locking differentials (lockers) significantly enhance traction.

The TJ’s design encourages a DIY approach, and countless online forums, videos, and dedicated shops exist to support owners in their modification journeys. This vast ecosystem makes it easy to find parts, advice, and assistance, further cementing the 1998 TJ’s status as a timeless canvas for off-road enthusiasts.
