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