Construction & Design

The Fabtech 4-inch Performance System features meticulously engineered components crafted from high-quality materials. The high arched lower control arm crossmembers are made from 1/4-inch thick steel, providing exceptional strength to handle off-road impacts and heavy loads. The OE forged steel upper control arms utilize ductile iron steering knuckles, which are designed to retain the stock track width, preserving factory handling and steering feel.

The system's design emphasizes durability and precise fitment, with components engineered through CAD development and manufactured to strict tolerances. The use of heavy-duty steel and robust welds ensures the suspension can withstand rigorous off-road conditions while maintaining alignment integrity. The rear lift blocks and u-bolts are engineered for strength and stability, completing a balanced suspension upgrade.

Performance & Sound

This lift system enhances your vehicle's off-road capability by increasing ground clearance and allowing for larger tires, which improves approach, departure, and break-over angles. The upgraded suspension components help support increased wheel travel and better handling over rough terrain. While specific horsepower or torque gains are not claimed, the system's improved airflow and suspension geometry contribute to a more responsive and confident driving experience. The kit maintains a factory-like ride quality, ensuring comfort during daily driving while providing the durability needed for off-road adventures.

Installation & Fitment

The Fabtech 4-inch Performance System is designed as a bolt-on upgrade, making installation straightforward for experienced DIY enthusiasts or professional installers. The kit retains the factory track width, so no additional wheel spacers or modifications are necessary to achieve a balanced stance. The installation involves replacing the factory control arms, crossmembers, and rear blocks, with all hardware included for a complete setup.

No cutting, drilling, or complex modifications are required, and the system is engineered to fit seamlessly with your vehicle's existing components. Proper alignment is recommended after installation to ensure optimal handling and tire wear.
