Rough Country 2-inch Lift Kit Installation Manual

Introduction

This manual provides comprehensive instructions for the proper installation, operation, and maintenance of the Rough Country 2-inch Lift Kit, Model 764. This kit is specifically designed for 2010-2024 Toyota 4Runner 4WD vehicles. Adherence to these instructions is crucial for ensuring the safety, performance, and longevity of your vehicle and the lift kit components. Please read this manual entirely before beginning any installation procedures.

Important Safety Information

Rough Country recommends that a certified technician install all lift systems. Knowledge of Rough Country instructions, proper suspension procedures, and post-installation checks are required. If a system is installed without the necessary knowledge and expertise, it may compromise the integrity and operating safety of the vehicle.

It is the buyer's responsibility to ensure all bolts and nuts are checked for tightness after the first 500 miles of operation, and subsequently every 1,000 miles. The wheel alignment, steering system, suspension, and driveline systems must be inspected by a qualified, professional mechanic at least every 3,000 miles.

Installation Instructions

Pre-Installation Checklist

1. Read all instructions thoroughly before beginning.
2. Ensure the vehicle is parked on a level, stable surface.
3. Engage the parking brake and chock the rear wheels.
4. Disconnect the negative terminal of the vehicle's battery.
5. Measure and record the vehicle's initial ride height from the ground to the fender lip at each wheel.

General Installation Steps (Front Suspension)

These steps provide a general overview. Refer to the detailed instructions provided with your kit for specific torque values and procedures.

1. Safely lift the front of the vehicle and support it with jack stands. Remove the front wheels.
2. Disconnect necessary components to allow for strut removal (e.g., sway bar links, brake lines, ABS wires).
3. Remove the lower strut bolts and the upper strut nuts. Carefully remove the strut assembly from the vehicle.
4. Install the provided strut extensions and/or coil spring spacers according to the kit's specific instructions. This may involve disassembling the strut or simply bolting the spacer to the top or bottom.
5. Reinstall the modified strut assembly into the vehicle, ensuring all bolts are hand-tightened initially.
6. Reconnect all previously disconnected components.
7. Torque all fasteners to the manufacturer's specified values.
8. Reinstall the front wheels and lower the vehicle.

General Installation Steps (Rear Suspension)

These steps provide a general overview. Refer to the detailed instructions provided with your kit for specific torque values and procedures.

1. Safely lift the rear of the vehicle and support it with jack stands. Remove the rear wheels.
2. Support the rear axle with a jack. Disconnect necessary components to allow for coil spring removal (e.g., sway bar links, brake lines).
3. Carefully lower the axle to allow the coil springs to be removed.
4. Install the provided coil spring spacers on top or bottom of the coil springs as per instructions.
5. Reinstall the coil springs with spacers and raise the axle.
6. Reconnect all previously disconnected components.
7. Torque all fasteners to the manufacturer's specified values.
8. Reinstall the rear wheels and lower the vehicle.

Operating Considerations

After installing the lift kit, the vehicle's center of gravity will be raised. This may result in changes to handling characteristics, particularly during cornering and braking. Drive cautiously until you become accustomed to the vehicle's new dynamics. Ensure adequate tire clearance for larger wheels and tires, if installed.

Maintenance

Regular maintenance is essential to ensure the continued safe operation of your lifted vehicle. Adhere to the following schedule:

• After 500 Miles: Re-check the tightness of all bolts and nuts associated with the lift kit installation.
• Every 1,000 Miles: Periodically inspect all fasteners for proper torque.
• Every 3,000 Miles: Have a qualified professional mechanic inspect the wheel alignment, steering system, suspension components, and driveline systems.
• Regularly inspect all suspension components for wear, damage, or corrosion.

Troubleshooting

Common Issues and Solutions

• Issue: Strut bolts are too long and prevent proper seating of spacers.
  Solution: On some Toyota 4Runner models, the original strut bolts may be longer than the height of the spacers. It may be necessary to carefully cut or grind a portion of the strut bolts to allow the spacers to fit flush. This modification should only be performed by a qualified individual with appropriate tools and safety precautions.
• Issue: "Clunking" noise from the front suspension after installation.
  Solution: This can indicate that the front shocks are bottoming out, especially with stock shocks. Ensure all components are correctly installed and torqued. If the issue persists, consider upgrading to extended-length shocks designed for lifted applications. Consult a professional mechanic for diagnosis.
• Issue: Vehicle pulls to one side or steering feels off.
  Solution: An alignment is absolutely critical after installing any lift kit. Have a professional alignment shop perform a full wheel alignment immediately after installation.
