Right now (since it was designed for off road) there is a 1.25" bumper attached to the bottom of the upper control arms that contacts a dedicated flat pad welded to the Frame. I think I'm going to drill and tap the flat pad to allow me to put an adjustable bumper in to contact the UCA. Right now the static rise is 5.5" before it makes contact, probably a little "generous" considering the 85.5" wheelbase, huh?

With the old 4K stall 9 1/2" converter it would just hike the wheels 6-8" and it was really easy to drive. With the 8" I'm feeling maybe another 50 hp worth of torque within 3 feet off the line, like I said it's like a nitrous shot by comparison.
