I assume you have Caltracs on your truck? I don't go to the drag strip, and could care less about 60' times...but I do have a valve body installed and worry about the axle
rotation. I like the Caltrac option, but am worried about the rattling reported. Can you put a small rubber hose around the top pin sitting atop the fwd end of the leaf spring? I wouldn't want to pre-load them, since that stiffens up your ride too much. Hate to go with long bars, but don't want rattle or a stiff suspension. What's your opinion.??
