I've seen them face up and work, seen them slope down and work...give your truck what it wants and don't worry about that bar angle.

if you're consistently hooking now, leave it alone. if you keep throwing more power at it the way it sits you will eventually have traction issues.

you're probably hitting the tire too hard with that preload.

Your truck has no antisquat when you leave. In my opinion your back bracket needs to be lower, the lower the bottom bar is away from the axle, the more leverage its going to give to the front bracket. As for the front bracket as well, the lower it is, the more leverage it has. You still want some angle tho imo..

loosen that preload and if it still hits too hard on the street, try the top hole on the axle side. don't be afraid to leave a small nickel sized gap on the spring. keep the shocks turned up firm for now. that's what I would do anyways.

calvert says that the top hole on the leaf spring eye hits harder than the lower holes. I've never confirmed it as right or wrong but they should know their product best. I know with my Silverado I tried my best to make the bar level...I've had more success with caltracs once I threw that idea out and just watched how the suspension responds and go from there.

Lets see if i understand this right, u recommend the bar being lower all together, the rear further away from my axle and front further away from the leaf spring mount?

What kind of preload do you recommend on the street?
without transbrake how do u launch on the street? try to hit it hard? apply the throttle slowly? without boosting? seems like there are so many different options lol
