1. Introduction
This manual provides instructions for the Rough Country 1.5-2 inch Leveling Lift Kit, Model 28330. This kit is designed to adjust the vehicle's stance and accommodate larger tires. It is compatible with 1999-2006 Chevrolet Silverado 1500 and GMC Sierra 1500 trucks. This kit also fits 2007 "Classic" models but does NOT fit HD models or 1999 Classic (old body style) models.
The kit includes components to raise the front of the vehicle by 1.5 to 2.5 inches and the rear by 3 inches, allowing for up to 32-inch tires with factory backspacing.
2. Safety Information
It is the installer'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. Regular inspection of the wheel alignment, steering system, suspension, and driveline systems by a qualified professional mechanic is recommended at least every 3,000 miles.
Always use appropriate safety gear and follow all local safety regulations during installation and maintenance. If you are not confident in performing the installation, seek assistance from a certified professional.

3.2 Key Installation Steps (Overview)
- Front Lift: Install the forged torsion keys. These keys allow for fine-tuning of the torsion bar to achieve the desired front lift, ranging from 1.5 to 2.5 inches. The forged construction provides enhanced strength compared to cast iron alternatives.
- Rear Lift: Install the 3-inch rear lift blocks and shock spacers. These components work together to raise the rear of the vehicle and ensure proper shock function with the increased ride height.
- Shock Installation: Replace existing shocks with the included Premium N3 Shocks, designed to accommodate the new lift height and maintain ride quality.
- Hardware: Secure all components using the provided mounting hardware and U-bolts. Ensure all fasteners are torqued to manufacturer specifications.
After installation, a wheel alignment is required to ensure proper vehicle handling and tire wear.

4. Operating Considerations
After installing the leveling lift kit, the vehicle's center of gravity may be altered. Drivers should be aware of potential changes in handling characteristics, especially during cornering and braking. Always drive cautiously and familiarize yourself with the vehicle's new dynamics.
The kit allows for the use of tires up to 32 inches in diameter with factory backspacing. Ensure that any new tires and wheels are properly balanced and aligned to prevent premature wear and maintain safe operation.
5. Maintenance
Regular maintenance is crucial for the longevity and safe operation of your vehicle after installing the lift kit. Adhere to the following maintenance schedule:
- Initial Inspection (500 miles): Re-check the tightness of all bolts and nuts installed with the lift kit.
- Routine Inspection (Every 1,000 miles): Periodically check all bolts and nuts for tightness.
- Professional Inspection (Every 3,000 miles): Have a qualified mechanic inspect the wheel alignment, steering system, suspension, and driveline systems.
- Component Check: Regularly inspect shocks, torsion keys, and lift blocks for any signs of wear, damage, or corrosion.
6. Troubleshooting
This section addresses common issues that may arise after installing the leveling lift kit.
- Vehicle Pulling to One Side: This often indicates an alignment issue. A professional wheel alignment is critical after installation to correct toe-out conditions and ensure proper tracking.
- Stiffer Ride: The Premium N3 Shocks are designed for performance on and off-road. Some users may perceive a slightly firmer ride compared to factory suspension. This is generally normal for performance-oriented shocks.
- Unusual Noises: Check all mounting points for proper torque. Ensure no components are rubbing against each other or the vehicle frame. If torsion keys were difficult to remove during installation, ensure their replacements are seated correctly.
- Uneven Stance: Verify that the torsion keys have been adjusted correctly to achieve the desired front lift. The adjustable range allows for precise leveling.
If issues persist, consult a professional mechanic or contact Rough Country customer support.
