When going to the RAD design you will save time during assembly by not having to use the ball joint housing. You will gain clearance around your shock and spring because of the ring being much smaller and the new design shape allowing up to a 5" diameter coil over spring. This design also cuts a pound out of your control arm and the best part is it saves you money by not having to buy the Ball Joint Housing.
