options on "stretching" a Blazer???

without worrying about hitting the gas tank.

I have plenty of clearance with the gas tank since I have relocated it into the bed . This may sound dumb, since there are 100's of 52" and 56" threads on here, but how do you get lift from these springs? Is it because they are so long? I really don't want to change these springs out if I can help it.

Stock front springs are flat. Stock rear springs have the same arch in them as 4" front lift springs. When the weight gets on them they end up at about the same height (looks like more lift with the 52s but the springs are also longer).

just found out that the Suburban I bought for the TBI swap has 56" springs in the rear...will these work on the rear on mine??? and how will they work with the 4" shackle flip already installed? sorry this is going on so long.
