This 4" Performance Suspension System is designed for 2011-19 Chevrolet Silverado 2500HD and GMC Sierra 2500HD 2WD/4WD models, delivering a robust suspension upgrade using Fabtech’s proven heavy-duty construction and engineering. The system provides increased ground clearance while maintaining a clean, factory-style appearance.
The front suspension features high-arched lower control arm crossmembers constructed from heavy-duty 1/4" thick steel to ensure maximum strength and long-term durability under demanding driving conditions. Fabtech ductile iron steering knuckles are engineered to retain a near-stock track width, keeping the tires properly positioned under the fenders.
A front differential skid plate is included to provide added protection against road debris and off-road obstacles, helping safeguard critical drivetrain components. Rear lift is achieved using a block and U-bolt configuration to maintain proper stance, load capacity, and ride quality.
