In order to get the most out of the new Super-Flex rear leafs, I had to do some modifying to the rear shackle hanger. By clearancing the inside of the shackle (yellow arrow) and forming the hanger inwards (orange arrow), a significant amount of shackle travel increase was able to be had. The entire spring pack was allowed to move forward, which therefore also allowed the entire spring pack to move downward another 3-4 inches with little effort. The way the springs were designed (free-length), this can only happen when one wheel is up, and the other is down (fully articulated). Therefore, this 'extra' axle droop won't occur during hard brake stops, or when declining steep downhill descents. At the same time, crisp handling both on and off road is had as well. Further refinements are needed in order to complete this project, and release it for resale. As always, nothing is put on sale unless it's trail tested-tuff and power-proven.

Actually, the two photos to the right are the front of my Black Thunder '67 Bronco with our custom made suspension setting rods in place (yellow arrow). With these rods in place of the coils, even the smallest rear suspension geometry and flex can be determined and set without interference from the front suspension influencing the results. Note (orange arrow) the tubes going to and from the engine to the isolated rear mounted aluminum radiator. Here I'm preparing the front suspension for the proto-type 5-link system, where special rods will be placed in the rear to eliminate any influence from the leafs.
