Jeep XJ Steering Box Spacer FAQ
Do I need a steering box spacer for my stock Jeep XJ?
While not mandatory for a stock vehicle, a spacer is highly recommended if you run larger tires, a lift kit, or do any off-roading. It prevents the unibody from cracking at the steering box mount, a common failure point on XJs.
Will a steering box spacer my loose steering?
It can help, but only if the looseness is caused by frame flex or a cracked mounting area. If your steering issues stem from a worn gearbox, tie rods, or ball joints, the spacer alone will not solve the problem.
Can I install a steering box spacer without removing the steering box?
Most spacers require at least loosening or partially removing the steering box bolts to slide the spacer into place. Full removal of the gearbox is often easier for access, but some designs allow for installation with the box still mounted.
What is the difference between a spacer and a brace?
A spacer simply fills the gap between the steering box and the frame, while a brace adds a second connection point to the opposite frame rail. A brace provides significantly more rigidity and is better for heavy-duty use.
Will a steering box spacer fit my 1999 Jeep Cherokee XJ with a lift kit?
Yes, most spacers are designed to fit all 1984-2001 XJs regardless lift height. However, check for clearance with aftermarket steering components like a dropped pitman arm or aftermarket track bar.

I’m Theodore Roosevelt—though my friends just call me “Ted” (and no, I’m not related to the president, though I do share his love for adventure). I grew up in Detroit in the 1970s, back when the city was still the heart of the American auto industry. My first love was a rusted-out 1967 Mustang my father and I rebuilt in our garage when I was fifteen. That project taught me that cars have souls. After spending twenty years as a mechanic and another ten writing for magazines, I started this blog to help everyday drivers and weekend wrenchers feel confident under the hood. Whether you’re restoring a classic or just trying to keep your daily driver alive for one more winter, I’m here to help you get there.
