If you're looking to upgrade your XJ to the hefty dual brake system that the WJ has, you'll need some wheel bearing spacers, and we have brought our always high-quality steel to the spacer game. These properly align the u-joint with the ball joint pivot centerline and keep those brake rotors in check so you can make sure your upgrade doesn't go out on you.
