Why Choose the Jeep WJ 4-Inch Lift with 33s?
The Jeep Grand Cherokee WJ, produced from 1999 to 2004, has earned its place as a legendary SUV among off-road enthusiasts. Its sturdy unibody frame and reliable drivetrain make it an ideal platform for modifications. But what makes the 4-inch lift with 33s setup so appealing?
- Increased Ground Clearance
A 4-inch lift gives your WJ the clearance it needs to conquer steep inclines, rocky trails, and deep ruts without scraping the undercarriage. Pairing this lift with 33-inch tires further boosts the ride height for improved off-road capability. - Aggressive Look
There’s no denying that a lifted Jeep WJ running 33s looks bold and commanding. The combination gives your vehicle an aggressive stance that turns heads, whether on the trail or in a parking lot. - Improved Off-Road Performance
Larger tires and increased suspension travel allow your Jeep to handle rough terrain with ease. The added lift makes it easier to climb over obstacles, while the 33-inch tires provide better traction and stability. - Versatile Setup
The 4-inch lift is perfect for those looking for versatility. It strikes a balance between off-road performance and on-road drivability, making it an excellent option for daily drivers who also love hitting the trails.
Choosing the Right 4-Inch Lift Kit for Your WJ
Selecting the right lift kit is crucial for achieving the perfect Jeep WJ 4-inch lift with 33s setup. With several brands and options available, it’s important to choose a kit that matches your off-roading goals and budget.
1. Types of Lift Kits
- Short-Arm Lift Kits: These are more budget-friendly and easier to install. They maintain the factory control arms but use spacers and extended springs to lift the vehicle.
- Long-Arm Lift Kits: These provide better articulation, stability, and ride comfort on extreme trails. While they are more expensive and require more work to install, they’re the go-to for hardcore off-roaders.
2. Recommended Lift Kit Brands
- Rough Country 4-Inch Lift Kit: Known for affordability and durability, Rough Country kits offer a great entry point for beginners.
- Iron Rock Off-Road (IRO) 4-Inch Lift: IRO is popular among Jeep enthusiasts for its robust components and excellent articulation.
- Clayton Off-Road 4-Inch Long-Arm Kit: If you’re serious about off-roading, Clayton’s long-arm kits deliver unmatched performance and durability.
3. Lift Kit Components to Look For
A quality 4-inch lift kit typically includes:
- Lift springs
- Shocks or shock extensions
- Track bar relocation brackets
- Control arms (short or long)
- Brake line extensions
- Sway bar links
Make sure the kit you choose includes everything you need for a smooth installation and improved performance.
Installing 33-Inch Tires on a Jeep WJ
Once you’ve installed your 4-inch lift, the next step is fitting those 33-inch tires. This process is relatively straightforward, but there are a few important considerations to ensure proper fitment and performance.
1. Wheel Size and Backspacing
To fit 33-inch tires without major rubbing, you’ll need wheels with the proper backspacing. A backspacing of 3.75 to 4.5 inches is ideal for a Jeep WJ with a 4-inch lift. This provides the clearance needed for the tires to sit comfortably without rubbing on the suspension or fenders.
2. Trimming and Fender Clearance
Even with a 4-inch lift, you may experience minor rubbing at full suspension flex or when turning sharply. To prevent this:
- Trim the front fender liners slightly.
- Consider adding extended bump stops to limit upward tire travel.
- If you’re tackling aggressive trails, a little fender trimming will go a long way.
3. Choosing the Right Tires
- All-Terrain Tires: Perfect for drivers who split their time between on-road and off-road driving. They offer solid grip on trails without sacrificing comfort on pavement.
- Mud-Terrain Tires: Designed for extreme off-road use, these tires provide excellent traction in mud, sand, and rocks but can be noisier on the road.
Popular tire options for a WJ include the BFGoodrich KO2s, Nitto Ridge Grapplers, and Falken Wildpeak AT3Ws.
Suspension and Drivetrain Adjustments
Lifting your WJ and installing 33-inch tires will affect the suspension geometry and drivetrain. To maintain performance, safety, and durability, you’ll need to make a few additional adjustments.
1. Re-Gearing for Larger Tires
Larger tires can throw off your gear ratios, leading to decreased power, slower acceleration, and higher fuel consumption. Re-gearing your differentials to 4.10 or 4.56 ratios will restore lost performance and improve drivability.
2. Adjusting the Track Bar
A 4-inch lift will shift your axle slightly due to changes in suspension geometry. Installing an adjustable track bar will recenter the axle and prevent steering issues.
3. Upgrading Brakes
Larger, heavier tires increase stopping distances. Consider upgrading to high-performance brake pads and rotors to ensure your Jeep stops safely and effectively.
4. Correcting Driveshaft Angles
Lift kits can alter the angle of your driveshaft, leading to vibration at higher speeds. Installing a slip yoke eliminator (SYE) or adjustable control arms can help correct this issue.
Optimizing Ride Quality and Handling
A lifted Jeep WJ with 33s doesn’t mean sacrificing comfort and handling. Here’s how you can optimize your setup for both on-road and off-road driving:
- Quality Shocks
Invest in high-quality shocks like Bilstein 5100s or Fox 2.0 shocks. They provide excellent damping, ensuring a smoother ride over rough terrain. - Sway Bar Disconnects
Sway bar disconnects allow for maximum articulation when off-roading, while reconnecting them restores stability for highway driving. - Wheel Alignment
After lifting your Jeep, always get a professional alignment. Proper alignment prevents uneven tire wear and ensures predictable handling. - Tire Pressure Adjustments
Adjust tire pressure based on your driving needs. Lower pressures (20-25 PSI) improve traction off-road, while higher pressures (30-35 PSI) are ideal for on-road driving.
Benefits of the Jeep WJ 4-Inch Lift with 33s Setup
To summarize, here’s why this setup is a game-changer:
- Enhanced Off-Road Capability: Conquer tough trails with increased clearance and improved traction.
- Aggressive Aesthetic: Stand out with a bold, lifted look that complements the WJ’s design.
- Versatility: Enjoy a Jeep that’s equally capable on trails and comfortable on highways.
- Customizable: From lift kits to tires and drivetrain upgrades, you can fine-tune this setup to meet your needs.
Common Challenges and Solutions
