If you want to mount your 3/4” sway bar between your frame rails but don’t have a crossmember to mount it on, you can use these bearings to hold the bar in place. Use split collars (see option 1) to keep the bar centered if you can’t mount the arms right beside the bearing.

You’ll have to drill out the arms to let the bar pass through.

Oil-embedded bronze bearing is self-aligning. Mounting holes are 3/8”, 2-1/2” c-c. Total thickness is about 15/16”. Sold individually.
