Hell Bent Steel Supeneion lift any good?

Hey I am looking to buy a lift kit from hell bent steel it's a ready lift style kit (ie; spacer kit between the coilover shock and mounting tower bracket) in the front suspension. I have a few questions is this a good product and has anyone had trouble with it and if I do raise the front will I have to raise the back to make it level again? If so the website doesn't show any rear leveling kits. Could I just use a piece of plate steel to extend the leafs vertically and leave the stock shocks in use still or would I have to get extended shocks too? I am looking at the 3" leveling kit- lift kit for the front I have a 2010 Tacoma 4x4 inline 4 5spd
