Installation & Fitment Notes: UMI recommends installing the 3054 bracket kit, mocking up the ride height as desired, then purchasing the correct length shocks.

The 3054 will also fit on the Quick Performance single hole non-adjustable bracket but will not have the ability to adjust the lower control arms.
