Fabtech’s world-renowned IFS suspension system for the GM 2500HD is engineered to deliver outstanding drivability, strength, and control both on the highway and offroad. Designed with zero bump steer throughout the entire suspension cycle, this system significantly reduces driver fatigue while improving steering precision and overall vehicle stability.
The near stock track width keeps the tires properly tucked under the fenders for a clean, factory-like appearance. Fabtech’s proprietary steering knuckle geometry enhances lock-to-lock turning radius, allowing for confident maneuvering in tight spaces without sacrificing on-road handling.
Heavy duty 1/4" thick steel crossmembers are built with eccentric-style alignment cams for easy adjustment while delivering exceptional structural integrity. Triple front differential mounts precisely reposition the differential to maintain proper CV and driveshaft angles, ensuring smooth and vibration-free 4WD operation at higher speeds.
This system is equipped with Fabtech’s top of the line Dirt Logic 2.25 shocks, featuring stainless steel bodies and NitroSteel piston rods for maximum corrosion resistance and durability. These high-performance shocks provide excellent damping characteristics for aggressive offroad use while maintaining a refined, controlled ride on pavement.
Every component of this suspension system is carefully engineered to work together, allowing proper wheel travel, eliminating over-cycling, and preserving steering geometry. Backed by a free 5 year 60,000 mile Powertrain Warranty, this kit delivers confidence, performance, and long-term reliability.
