The JBA UCAs install easy and make the FJ ride and handle great by correcting the geometery. If you have the front spacer econo- leveling kit (like me) your rig needs theses UCAs because the upper ball joint is getting badly stressed. Do your research but these are the best bang for the buck and have patented extend range replaceable ball joints which is just icing on the cake. Pic show full lock with 32” tires and just like JBA said no wheel spacer is needed up to 32”. If you’ve any mysterious clunking see the video. Our upper ball joints were totally shot from over extension.
