so you could just "not do that" too
LOL! Good luck with that.
I remember your spring picture post now. Even without dumping the clutch, a spirited take-off will wrap them up pretty good also. Big tires, like Ross mentioned, just compounds the problem. That's a pretty good spring package and you only have 2 unclamped support springs, so that should help a lot. Re-drilling the clamp on the rear so that the bolt is closer to the springs will help also if you find you have a problem.
A torque bar is pretty easy to make if the need arises.
That's going to be a FUN truck when you get it on (or OFF!) the road
