XJ Front Bottom Frame Stiffeners Reinforce your front unibody rails for serious off-road strength and long-term durability. These front bottom stiffeners are designed to protect and reinforce one of the most vulnerable sections of your Jeep Cherokee XJ — from the front of the unibody rail down to the factory lower control arm pocket. Whether you're prepping for a long-arm build or just want to eliminate flex and cracking, these are a must-have addition. Made from 3/16" steel, they’re tough enough to take a hit and strong enough to support linked suspensions. We were the first to offer this style of stiffener, and we’ve included an optional cover plate that ties in where the factory control arm pocket was — perfect for those planning a future 3-link or 4-link setup.
