Full Stiffener Kit For Jeep XJ

XJ Front Bottom Frame Stiffeners Complete reinforcement package to give your Jeep XJ the frame strength it always needed. This kit bundles all of our Jeep Cherokee XJ frame stiffeners into one package. By reinforcing the unibody from front to rear, it drastically improves rigidity, strength, and long-term durability. Whether you’re rock crawling, daily driving, or hauling gear, these stiffeners prevent flex and fatigue in one of the XJ’s weakest points — the frame rails. Installing them provides a solid foundation for suspension upgrades, heavy bumpers, and hard trail use. Each piece is laser-cut and formed for a precise fit. The kit covers the front, mid, and rear sections, plus an inner steering box plate to keep the box mount solid under stress. Welded in place, these stiffeners tie the unibody together and help your XJ handle abuse that would otherwise twist and crack the stock structure.
