I have no complaint with bds and I know nothing about the kit other than the expense and like you if I was to have someone else install a lift kit would go off there word over someone from the internet.That being said I worked in a Gm dealer for 10 yrs and Ford for 7 I was flat rate and ASE certified , I hold GM,Ford,Mitsubishi Fuso ,Isuzu, Chrysler and International Truck certifications ( granted many are from years ago). I have been running as Shop Dispatcher International Truck Dealership for about 6 years. So I feel that I can give the honest review of the kit I installed. I cannot review all of there products. I can also tell you from experience that alot of people that consider themselves mechanics will do more damage to your truck than any kit will. So looking for a reputable shop would be #1 concern if I was to have anyone work on my truck . Then I like you would probably go with what they recommend.
I installed my kit myself. There were a couple issues I wrote a review in this thread about my experience. If people want to comment on their experience I can take accept that.
What I can't accept is people saying RC is "shit" with no experience to back that up.
