This "Do It Yourself" package completely replaces all of the joints in your RE control arms and includes weld-on upper rear axle brackets that correct the geometry for proper use with the Game Changing Duroflex Joints.
It is required to cut off the end-rings of the existing control arms and weld on the new MetalCloak end rings in order to use this system; the factory upper rear axle brackets must also be cut off and replaced with the included MetalCloak brackets.
