Will This work

[TheMessenjah]

I was wondering if anyone knew if this would actually work. One of my friends told me that you could safely use a 2wd spindle lift on a 4wd truck as long as you don't go over 4 inches, does anyone know if thats true? I really would like an extra 4 inches of lift with a real kit not just the t-bar and block lift I have now. I found a fabtech 4 inch spindle lift for like 500 so I was wondering if any of you guys lknew anything about this.
