This 4" Performance Suspension System is designed for 2011-19 Chevrolet Silverado 2500HD and GMC Sierra 2500HD 2WD/4WD models, providing a strong and reliable suspension upgrade using Fabtech’s proven heavy-duty engineering. The system delivers increased ground clearance while maintaining a clean, factory-style stance.
The front suspension features high-arched lower control arm crossmembers constructed from heavy-duty 1/4" thick steel for maximum strength and durability under demanding conditions. Fabtech ductile iron steering knuckles are engineered to retain a near-stock track width, keeping the tires properly positioned under the fenders for a clean appearance and correct suspension geometry.
A front differential skid plate is included to help 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 capacity, and overall suspension balance.
