Can they be run without drilling a new hole in the frame for the shackle?
Yep, too lazy to search.

52's up front

You could set the truck on it and see what the shackle angle looks like. 
Otherwise you could just use 56's. All of their length is at the tail end of the spring. Your axle ends up the same place but the rear eye ends up ~4" farther back.
If you get un-lazy. Search my user name. I compiled a ton of links to different 52"/56" threads and posted them in the garage.

I want to use 2" or 2.5" springs to add a little more lift. What does this lift amount to overall in lift? I'm guessing 6".

Wow, really?
So you could run 56s with stock steering?
No, a 56 moves the axle to the same place as a 52.

They net about 4" of lift. So yeah, a 2" spring should give you about 6"...if anyone makes a 2" spring.

I've got 2.5" 52's on mine with the overload removed, I swear it's closer to 8" than 6". I expected 6"ish but it seems way tall.

Tuff Country makes 2" lift front and rear spring packs for GM's. Yes 2" not 2.5".
I don't want to move the D60 forward either. Which hole in the A-Bomb do you use to keep the axle center as in stock position?
IIRC Kert and I discussed this the other day and with the B52 bracket in the rear position you use the rear-most hole. I don't know where the a-bomb positions the spring brackets though.
Best bet is to give him a call or shoot him a PM. I'm not 100% certain on which set of holes to use to keep the axle in the factory location.

A-Bomb holes will be the same as the B52's. I just want to keep the front axle in the same position as it came from the factory.
i ran my lifted 52's in the stock location on my k30 with b52's and the angle was almost straight up and down.
Yes, but with B52's there are actually 2 sets of holes that go to the frame. There is a forward and rearward position, hence the "slot" for the body mount. That means that there's 8 possible positions (2 sets of frame holes + 4 spring holes). I don't know which frame position the a-bomb is set up for.
Give him a call.
Give him a call.
My axle is forward, idk 2~3 or so. I have my B52's in the rearward position with the spring in the forward most hole. I also move the rear hanger forward.
Ok, got ya now. I was wondering about those extra holes in those brackets. Makes sense now.
My goal is to run the front axle right where it came from the factory as. With 52" or 56" springs and NOT drilling a new hole in the frame on the shackle end.

Did you drill a new hole in the shackle end, John?

That thing looks really badass though
This is just off the cuff guesstimating now, but your shackle might have quite an angle. I don't know where the pins are located in factory front springs, but 52's are obviously longer, and the pins are centered. This *might* provide enough additional length at the tail of the spring to lean your shackle way back. Like I said, just guesstimating. I know Kert has said that guys have use B52's in the past while maintaining their factory axle location, but I have no idea how their shackle angle turned out.
If you really wanted to get fussy about shackle angle and axle location, you could order a set of EZ Inches. That way you could tune the shackle angle with the multiple spring hole locations on the a-bomb, and still have 1" and 1.5" increments to play with for axle movement on the EZ Inch brick. That would net you an additional inch of lift though, giving you ~5" with stock 52's and ~7" with 2" lift 52's.

How much are those new rear spring, front hangers and can they be made for 1/2 & 3/4 ton width perches?
