The factory steering linkage on 2001-2010 GM HD trucks is a known weak point that flexes and wears prematurely under heavy loads. This results in loose steering, alignment changes during 4WD operation, and potential tie rod failure, especially on trucks with larger tires or increased power. — The original equipment manufacturer (OEM) components, particularly the centerlink and tie rods, were not designed for the stresses of modern diesel torque, heavy towing, or off-road use with oversized tires. This leads to specific, common failures that this kit directly addresses. The stock stamped steel centerlink can flex under steering load, which is a primary cause of the vague or sloppy steering feel. In 4WD, the increased traction and torque can actually flex the weak factory tie rods, causing the front wheels to 'toe-in' and creating excessive tire wear. BD's upgrade kit replaces these weak links with a forged I-Beam centerlink that is 30% stronger and tie rods that are 1.5 times thicker than the OEM parts, preventing this flex and breakage.
