Hello
Yes we manufactured our relocation brackets to work with both OEM and aftermarket LCA's. But to tell you the truth I would highly suggest looking into a set of aftermarkets or even boxing yours in (but even if you do that the bushings will still be shot). And the frame braces do keep the torque boxes in good shape. Eventually if you are looking to put down some serious power the boxes will start to tear and bend. So I would suggest the frame braces for extra insurance. Below is a link to show you what all UMI Performance has to offer!
