Fabtech’s world-renowned IFS suspension system for the GM 2500HD is engineered to deliver exceptional on-road comfort and offroad capability without compromise. Designed with precision geometry and premium components, this system eliminates bump steer throughout the entire suspension cycle, reducing driver fatigue while greatly improving overall stability and steering control.
The near stock track width maintains a clean, factory-style appearance by keeping the tires properly tucked under the fenders. Fabtech’s proprietary steering knuckle design improves lock-to-lock turning radius, making tight maneuvers easier while preserving confident highway handling.
Heavy duty 1/4" thick steel crossmembers are built with eccentric-style alignment cams for easy adjustment and long-term durability. Triple front differential mounts precisely reposition the differential to maintain correct CV and driveshaft angles, ensuring smooth and vibration-free 4WD operation even at higher speeds.
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 long service life. These high-performance shocks deliver excellent damping for aggressive offroad conditions while maintaining a refined, controlled ride on the street.
Every component is carefully engineered to work together for proper wheel travel, accurate steering response, and reliable long-term performance. Backed by a free 5 year 60,000 mile Powertrain Warranty, this suspension system offers strength, confidence, and performance you can rely on.
