4. Operating Your Lifted Vehicle

After the Rough Country 6-inch Lift Kit is installed, your Ford F-150 will have increased ground clearance and the ability to accommodate larger tires. While the kit is designed to maintain factory-like angles and ride comfort, it is important to be aware of the changes to your vehicle's dynamics.

• Driving Dynamics: A lifted vehicle may exhibit different handling characteristics compared to a stock vehicle. Exercise caution, especially during turns and at higher speeds.
• Center of Gravity: The vehicle's center of gravity will be raised, which can affect stability. Drive responsibly and be mindful of this change.
• Off-Road Performance: The kit enhances off-road capability by increasing ground clearance. However, always assess terrain conditions and drive within your vehicle's and your own capabilities.
• Tire Pressure: Ensure proper tire pressure for your larger tires as recommended by the tire manufacturer, not necessarily the vehicle's original specifications.

5. Maintenance

Proper maintenance is crucial for the longevity and safe operation of your Rough Country 6-inch Lift Kit and your vehicle.

• Fastener Checks: Re-torque all suspension bolts and nuts after the first 500 miles of driving. Subsequently, check and re-torque every 1,000 miles. This prevents loosening due to settling and vibrations.
• Component Inspection: Every 3,000 miles, have a qualified mechanic inspect the wheel alignment, steering system, suspension components (struts, shocks, knuckles, crossmembers, brackets), and driveline systems for wear, damage, or proper function.
• Cleaning: Regularly clean suspension components, especially after off-road use, to prevent accumulation of dirt, mud, or salt that can lead to corrosion or premature wear.
• Alignment: Periodically check and adjust wheel alignment, especially if you notice uneven tire wear or changes in steering feel.

6. Troubleshooting

This section addresses common issues that may arise after installing a lift kit. For complex problems, always consult a professional mechanic.

• Uneven Ride Height: Ensure all components are installed correctly and fully seated. Verify that the vehicle is on a level surface when measuring. Re-check torque specifications on all fasteners.
• Unusual Noises (Clunking, Squeaking): Inspect all bolts and nuts for proper tightness. Check for any contact between suspension components or between suspension and chassis. Lubricate bushings if necessary.
• Poor Handling or Steering Issues: A professional wheel alignment is critical after installation. If issues persist, check for loose steering components, worn ball joints, or incorrect caster/camber settings.
• Vibrations: Check driveline angles. Ensure U-bolts are properly tightened. Verify tire balance and wheel runout.
• Premature Component Wear: Ensure regular maintenance checks are performed. Over-tightening or under-tightening fasteners can lead to premature wear.
