I just spent the last 15+ mins talking to someone named Jared from Suicide Doors.com. He was awesome. I had tons of questions and he answered every one. We talked about different styles of air bags, 4 links, different setups for my application and he didn't pressure me to buy anything. I think i am going to buy all my stuff from them. Customer service like that is almost non-existant. If anyone here is looking for parts (4 link, air bags and ect.) you should give them a call. Sorry for going on and on but i was so impressed and had to share.
