That airbagit.com kit will not lay out 100% they don't sell raised crossmembers and the front brackets are not that great. Some of their parts are ok but you really got to deal with them a lot to know whats good and whats not, some of them are just plain garbage.
But yea shoot me an email to
brian@illusivefabrications.com for all quotes. And defiantly use this web site and rangerpowersports.com as good resources to figure out what kind of link setup you want to go with , bag over axle, bag on bar. If you want a slow basic manual valve system, fast electric valve setup or digital right height controller. There are lots of options when it comes to air ride.
If you email me be sure to include any suspension mods that have already been done to the truck so I know what I'm working with to put together a package.
I would highly recommend looking into the Air Lift AutoPilot V2 system for the air management I have a package deal here
http://shop.illusivefabrications.com/front-and-rear-air-kits/illusive-choice-air-management-kit-1/ Its top of the line but really does not cost much more in this package deal than a regular electric valve setup does.
A good kit is going to run anywhere between $1500-$2400 depending on what components are used and if your truck is already lowered with the parts needed for air ride to lay out.
