Making a 4x4 CCSB Hook!

I'm curious as to what I can do to make my 06 Lbz leave hard in 4x4 on street tires. I will be building a set of fully adjustable traction bars here soon. How should I adjust them for the track? I have already decranked the front all the way, and installed a 3" drop shackle and removed the overload leaf. I have tie rod sleeves, nothing else in the front end. I'm also running some cheap Monroe shocks on 275/55r20 continental performance street truck tires, 480 tread wear. I'm broke as hell being only 17 and still going to school full time, but I want to make this thing as fast as possible in full street trim with a stock tranny. That's my biggest limiting factor.
How do I get it to leave hard and straight at 7000#? What shocks are you high horsepower guys running? Are they mounted in the factory location?
How are you guys leaf spring packs set up?
How are your traction bars adjusted?
What about getting the front end to leave straight?
Plan on doing the weld in idler arm support, what about a centerlink support?
Any ideas? I'm relying on making the truck hook and go vs making a shit ton of power to be fast. Already have 4" straight exhaust and an AFE cold air, EFI live tunes from Kory will also be on the way soon. Also plan on a transgo jr with springs from Mike L to get cut time spent shifting to a minimum and save my poor 260k mile Allison. I hate to sound too optimistic but I think with the entire chassis dialed and a stock tranny tune and the mods listed above the truck has a 13.99 in it. Someone correct me if I'm way off.

My old truck went 13.65 on stock Allison with a transgo jr, 4" exhaust, EFI, and suspension work. I was cutting 1.72-1.80 60' times with 285/55 nitto's on 20x8.5 wheels with +10 offset.

Suspension wise on my old truck. I had a straight centerlink, sleeves, new idler arm, new pitman arm, DJM 3/5 drop kit, full leafs in rear, 55" traction bars.

Now for you to save some money and not buy the drop kit, just make sure you have stock keys and lowered down all the way. Have the braces for the Idler/Pitman arm. Straight Centerlink sucked trying to turn in parking lots. With a lowered vehicle at least. Lifted didn't have as much of a problem. Shock were Rancho 9000XL's, they were adjustable so it helped with the launches. You can pick up a set of 4 for around $300.

Lift pump will definatly help as well. Launch somewhere between 8-11 psi.

On my buddies 06, he has braces and sleeves, rancho 9000 adjustable shocks (runs tightest setting in front, softest in rear) 5ft traction bars (adjusted only by hand until it was as tight and locked it down (keep in mind if you go loading everthing and something breaks, the shock from the bars losing load is really gonna tear shit up) spring clamps on front of the leaf springs, and the torsion key bolts are MIA. and he has cut consistant 1.60 60fts.

I may be way off here but with a stock trans and turbo I think the way it is now will launch hard as hell in 4wd. I've never spun doing 15psi launches on decent asphalt.

I just replaced my straight centerlink with a stock and DHD brace because I could not stand the turning and tire wear. Huge difference now! Was cheap and took less than 15 min to install. Like a whole new truck when it comes to turning. Went to the track yesterday and cut consistent 1.70s. I had my buddies watch my front end during launches to make sure it wasn't toeing in they said it was nice and straight. In my opinion don't waste your money on anything else for the front end. DHD brace and sleeves is all I have on my built motor/trans running high 11s in the 1/4 and mid 7s in the 1/8.

Learn to search first, noob. Pretty much all your questions have been covered time and again.....

Caltracs (or spring clamps), adjustable shocks on front (at least), braces/sleeves or straight centerlink, torsions turned down (pass side kept raised 1/4" higher than drivers), proper tire pressure all play into it.

Those things allowed for 1.6x-60fts in my truck.
