Rather than modifying or removing the Beams for tire clearance, Fabtech provides replacement Offset Intrusion Beams. They are constructed of 1/4in thick steel and are a welded box design for maximum strength. Features: 1/4in thick steel. Full steer clearance for 33in tires w/ 3.5in System. Offset Intrusion Beam Kit.
