I have an add a leaf lift from JC whitney...took about 45 minutes pr spring pack and gave me about 2 inches more lift...the front and rear kits are like $55 a piece. I would stay away from the shackle lifts. You could also looki into a hockey puck body lift... I had my puck lift in (2 pucks at each body mount) for 3 years..none of them cracked or tore or anything...and they are real cheap...$1 a piece. Use them in combination with a add a leaf and your lift will only be around $150.00 !
I'm not afraid of dying...I'm scared of not living
