Fabtech’s world renowned IFS suspension design for the GM 3500HD is engineered to deliver outstanding drivability both on the highway and in demanding offroad conditions. Precision suspension geometry eliminates bump steer throughout the entire suspension cycle, helping reduce driver fatigue while significantly improving overall control and stability.
The near stock track width keeps the tires properly positioned under the fenders for a clean, factory-style appearance. Fabtech’s proprietary steering knuckle geometry maintains an excellent lock-to-lock turning radius, allowing confident maneuverability in tight areas without sacrificing ride quality.
Heavy duty 1/4″ thick steel crossmembers feature eccentric-style alignment cams for easy adjustment and long-term reliability. Triple front differential mounts precisely reposition the differential to maintain proper CV and driveshaft angles, ensuring smooth, vibration-free high-speed 4WD operation.
This system is equipped with Fabtech’s top of the line Dirt Logic 2.25 shocks, constructed with stainless steel bodies and NitroSteel® piston rods for maximum corrosion resistance and durability. These premium shocks deliver a superior ride quality on the road while providing excellent damping and control in offroad terrain. Every component is designed to work together for proper wheel travel, precise steering response, and dependable performance. The system is backed by a free 5 year 60,000 mile Powertrain Warranty.
