• Ensure the vehicle is securely supported on jack stands or a lift before beginning any work. Never rely solely on a jack.
• Refer to your vehicle's service manual for specific torque specifications and procedures.
• After installation, perform a thorough inspection of all fasteners and components.
• A professional alignment is required after installing new suspension components to ensure proper vehicle handling and tire wear.

Parts List

Verify all components are present before beginning installation.

Installation Instructions

Vehicle Preparation

1. Park the vehicle on a flat, level surface.
2. Engage the parking brake.
3. Chock the rear wheels to prevent movement.
4. Loosen the front lug nuts.
5. Raise the front of the vehicle using a suitable jack and support it securely with jack stands under the frame rails.
6. Remove the front wheels.

Removing Old Control Arms

1. Support the front axle with a floor jack to relieve tension on the control arms.
2. Locate the front lower control arms. Each arm is attached to the frame at one end and the axle at the other.
3. Using appropriate wrenches, remove the nuts and bolts securing the control arms to both the frame and the axle. Keep track of all hardware.
4. Carefully remove the old control arms from the vehicle. Note their orientation for comparison.

Installing New Control Arms

1. Position the new Superlift Lower Control Arm into place. Ensure the correct arm (driver or passenger side) is used.
2. Insert the new hardware (bolts, washers, nuts) through the mounting points. Do not fully tighten at this stage.
3. Repeat for the other lower control arm.
4. Once both new control arms are loosely installed, lower the axle slightly with the floor jack to allow the vehicle's weight to settle on the suspension. This helps in achieving proper bushing alignment before final tightening.
5. Tighten all control arm bolts to the manufacturer's specified torque. Refer to your Jeep Wrangler TJ service manual for exact torque values.

Final Steps

1. Reinstall the front wheels and tighten lug nuts to factory specifications.
2. Lower the vehicle completely to the ground.
3. Remove wheel chocks.
4. It is critical to have a professional wheel alignment performed immediately after installation to correct caster and ensure proper handling and tire wear.

Operating Considerations

After installing the Superlift Lower Control Arms, your vehicle's suspension geometry will be optimized for a 2-4 inch lift. This may result in a different driving feel, particularly in steering response and ride quality. Always drive responsibly and be aware of your vehicle's new capabilities and limitations, especially when off-roading.

• Initial Drive: Drive cautiously for the first few miles to familiarize yourself with the vehicle's altered handling characteristics.
• Off-Road Performance: These control arms are designed to improve articulation and durability for off-road use. However, always assess terrain and drive within your vehicle's and your own capabilities.
• Tire Clearance: Verify adequate tire clearance under full suspension compression and steering lock to avoid rubbing.

Maintenance

Regular inspection and maintenance will ensure the longevity and performance of your Superlift Lower Control Arms.

• Periodic Inspection: Every 3,000-5,000 miles, or after severe off-road use, inspect the control arms and all mounting hardware for signs of wear, damage, or looseness.
• Bushing Check: Examine the bushings for cracks, tears, or excessive play. Replace worn bushings as necessary.
• Hardware Torque: Re-torque all control arm bolts to factory specifications after the first 500 miles of driving and periodically thereafter.
• Cleaning: Keep the control arms free of excessive dirt and debris, especially around the bushings.
