Ekstensive did all the work...custom upper and lower a-arms, bag mount, shock mount, etc. The rear is a triangulated 4 link, lower bars forward and the upper bars back, bags over axle.

Bought the truck with the suspension and wheels already. I assume Ekstensive sourced them out. I hear it is very hard to get someone to chrome/black chrome semi wheels, so I am sure it was expensive.
