Yes, Rob, they can.
WS218500 kit: $325.00
Less WS10768-2 axle brackets: -$70.00
Plus WS477600-2 air spring brackets: 87.20
New total: $342.20
You will need to mount the shocks and we have #223101 @ $20.00 each (2 required). They are the basic formed bracket from http://18.104.22.168/online-store/axle-bracket-kit-for-coil-overs/ . You would use standard shock studs instead of the coil-over bolts and spacers.
Our standard freight charge would be extra.
Thanks for looking at Welder Series parts.
