Control freak suspension
I have the triangulated control freak set up and Viking double adjustables, I don't have the HP/torque you have at only 550 from a port injected roller 408. but I also don't have the weight or bias you do (scaled at 2960 with 1500 even on the nose). with 2" per side narrowed rear and 325/50"s it hooks hard and straight, is extremely adjustable and they were great to deal with. The frame rail brackets are welded in but are inboard also. the only change I made was to make the lower axle bracket a little lower (1-1/2") for ride height. It works very well with the HDK set up. I use a 12" ride height shock with 4" stroke
