Default Rear drop

Looked at the truck, and got tired of the raked look. Got the tape measure, and theres 1" difference between the front and back. How can I drop the rear 1" From what I understand, spindels will give me 2" and I tow a good bit, so I hate to pull a leaf. Whats my other options?

Not enough information here, do you just want to level it or are you looking for a level drop(you mentioned spindles)

Im guessing its not stock because NNBS have alot more than 1" of rake

So whats been done, and whats the final goal?

Do you mean there's a 1" block in there from the factory that can be removed? Is it as simple as it sounds? I mean, do you have to change anything (u-bolts, etc.)?? That's interesting. I have a "08 Sierra Denali that I was just about to order the 2" drop rear hangers for, but I might try this first.

Thanks. I just went outside and crawled under the truck so I can see now what I need to do. It looks like I might need to shorten the rubber bump spring/stop on the frame as well to get the same suspension travel. Has anyone done this, or is it not necessary?
The spring clamps go where? You mean clamp the spring (including the high load leaf) to increase the spring rate?

The spring clamps pull the bottom leaf up to the one above it. Will give you approx. 1 to 2" of drop. They are intended to prevent wheel hop. as far as cutting the bump stop, I think you should be ok with leaving it stock. You're just going to hav eto try it and see.
