Introduction 2001 Jeep Grand Cherokee 6 Inch Lift Kit: The Ultimate Guide to Altitude
Why a 6-Inch Lift for Your 2001 Grand Cherokee?
A 6-inch lift kit for your 2001 Grand Cherokee isn’t just about looks (though the increased ride height certainly adds to the aggressive stance). It provides several functional advantages:
- Increased Ground Clearance: This is the primary benefit, allowing you to navigate larger obstacles, rocks, and uneven terrain without scraping the undercarriage.
- Larger Tire Fitment: A 6-inch lift provides ample room for larger, more aggressive tires, further enhancing off-road traction and performance. Think 32-33 inch tires, depending on your specific kit and wheel offset.
- Improved Approach and Departure Angles: Higher bumpers mean you can approach and depart obstacles at steeper angles without damaging your vehicle.
- Enhanced Off-Road Capability: Combined, these factors dramatically improve your Jeep’s ability to tackle challenging off-road trails.
However, be aware that a lift of this magnitude also introduces changes to your vehicle’s handling and geometry, which we’ll address in detail.
Key Components of a 6-Inch Lift Kit (and What to Look For)
A quality 6-inch lift kit will typically include the following:
- Coil Springs: Longer coil springs replace the factory springs to provide the lift. Look for progressive rate springs, which offer a smoother ride on the road and better articulation off-road.
- Control Arms: Longer or adjustable control arms (both upper and lower) are crucial to correct the axle position and pinion angle after the lift. Incorrect angles can lead to vibrations and premature wear on drivetrain components. Adjustable arms are highly recommended for fine-tuning.
- Track Bar (Front and/or Rear): The track bar centers the axle under the vehicle. Often, a new, longer track bar or a track bar relocation bracket is included to correct the axle’s lateral position. Adjustable track bars are a great option.
- Shocks: Longer shocks are necessary to accommodate the increased suspension travel. Choose shocks specifically designed for lifted vehicles, as they offer improved damping and control.
- Brake Line Extensions: The increased ride height stretches the brake lines. Extensions are vital for safe braking. Stainless steel braided lines are a good upgrade.
- Sway Bar Disconnects (Optional, but Recommended): Disconnecting the sway bars allows for greater axle articulation, improving off-road performance. Quick-disconnects make this process easy.
- Pitman Arm Drop Bracket or New Pitman Arm: This corrects the steering geometry to minimize bump steer.
- Transfer Case Drop Kit or Slip Yoke Eliminator (SYE): A lift of 6 inches can cause driveline vibrations. A transfer case drop kit lowers the transfer case to reduce the driveline angle. A Slip Yoke Eliminator is a more robust solution, replacing the slip yoke with a fixed yoke and a longer driveshaft. The SYE is highly recommended for this much lift.
- Bump Stops: Extended bump stops prevent the suspension from bottoming out and protect the shocks.
- Hardware: All necessary bolts, nuts, and washers for installation.
Choosing the Right Kit: Factors to Consider
Selecting the right 6-inch lift kit for your 2001 Grand Cherokee depends on several factors:
- Your Budget: Kits range in price from relatively affordable to quite expensive. Consider the quality of the components and the features offered.
- Your Intended Use: Are you primarily looking for improved off-road performance, or do you want a balance of on-road comfort and off-road capability?
- Your Mechanical Skill: Installing a 6-inch lift kit is a complex project. If you’re not comfortable with extensive mechanical work, consider having a professional install it.
- Kit Reputation and Reviews: Research different brands and read reviews from other Jeep owners. Look for kits with a proven track record of reliability and performance.
- Completeness of the Kit: Ensure the kit includes everything you need for a complete installation, including driveline solutions (SYE or transfer case drop), brake line extensions, and any necessary hardware.
Installation: A Step-by-Step Overview (Professional Installation Highly Recommended)
Disclaimer: This is a general overview. Always refer to the specific instructions provided with your chosen lift kit. This is a complex and potentially dangerous task. Professional installation is strongly recommended.
- Preparation:
- Gather all necessary tools: Jack stands, wrenches, sockets, torque wrench, impact wrench (helpful), spring compressors, hammer, penetrating oil, safety glasses, and gloves.

Important Considerations and Potential Challenges
- Driveline Vibrations: This is a common issue with lifts of this size. The SYE is the preferred solution, but a transfer case drop kit can help.
- Bump Steer: Incorrect steering geometry can cause bump steer, where the steering wheel jerks when hitting bumps. Correcting the steering geometry with a drop pitman arm is vital.
- Brake Line Length: Ensure the brake line extensions are long enough to accommodate the full suspension travel.
- ABS Sensor Wire Length: The ABS sensor wires may need to be extended.
- Wheel Alignment: A professional wheel alignment is essential after installing a lift kit.
- Tire Rubbing: Even with a 6-inch lift, larger tires can still rub, especially at full lock. Adjusting the steering stops can help.
- Increased Roll Over Risk: Raising the center of gravity increases the risk of rollover. Drive carefully, especially on uneven terrain.
- Legality: Check local laws regarding vehicle lift heights and tire sizes.
Troubleshooting Common Issues
- Driveline Vibrations: Re-check driveline angles. Ensure the SYE or transfer case drop is properly installed. Consider adjustable control arms to fine-tune the pinion angle.
- Bump Steer: Double-check the pitman arm installation. Ensure the track bar and pitman arm are properly aligned.
- Tire Rubbing: Adjust steering stops. Consider trimming the fenders if necessary.
- Uneven Ride Height: Ensure the coil springs are properly seated. Check for bent suspension components.
