Since /forums/images/graemlins/k5.gif /forums/images/graemlins/burb.gif /forums/images/graemlins/truck.gif have such bad departure angles, moving the rear axle back helps a lot. After a shackle flip, it also helps to move the rear axle back into the center of the wheel wells, although it is not that far off. On a /forums/images/graemlins/k5.gif about the max you can move the rear axle back w/o hitting the tank is ~3" I think. /forums/images/graemlins/confused.gif Don't quote me on that one. Don't know about /forums/images/graemlins/truck.gif.
