I've got the revolver and the 12 leaf pack from AC and they work great. Though after a lot of abuse, the flat piece of steal that the plastic pad bolts to is now v shaped. Having someone weld a piece of angle iron to reinforce it is a good idea. Mine lost another 1/4" to 1/2" from bending.
You should be sitting slightly higher than stock but not as high as an aftermarket shackle. But you'll gain a lot more travel than both.
