The General believes in the virtues of IFS all the way up to its K3500 1-ton 4x4 pickups. As such, the 2500 sports A-arms and CVs up front. Why not? IFS lets the wheels absorb jolts and other forms of off-road mayhem without forcing both wheels to respond to bumps that are only on one side or the other. The 2500 shares the same front differential with its 3500 1-ton big brother. Fabtech's 8-inch 2500 HD suspension system smartly uses taller knuckles to allow the upper A-arms to stay in their stock mounting locations. The lower A-arms are dropped via a gusseted, crossbraced cradle. If there's one thing we'd like to smite the General (and most of the other OEMs) about the head for, it's the miniscule size of the tie rods. It just doesn't make sense to give truck buyers a truck equipped with a superior powerplant, bulletproof tranny, and tough differentials and then handicap the whole package by using noodle-sized tie rods to point the front wheels down the road or trail. The rest of the truck is off-road worthy, so why not give the buying public a steering system that's equally tough? Although not shown, Fabtech offers an HD replacement tie rod end system whose components are double the size of the stockers.
