With larger tires, the XJs, TJs and ZJs need all the help with stopping power that they can get. The WJ Grand Cherokee comes with much larger dual piston brake calipers and is largely compatible with the axles on the other vehicles, which makes converting to the WJ Knuckles and Calipers a great upgrade.
Rusty's flange spacer is designed to properly position the wheel bearing hub to the axle u-joint and brake calipers when using the WJ Grand Cherokee knuckles and brakes. Rusty's flange spacer is precision laser cut for an exact fit.
