Universal air ride suspension uses a less complicated manufacturing process but requires slightly more work when it comes to install.  If you are considering a Universal Air Ride Suspension Kit keep in mind you might need to do some modifications just to get it installed in your vehicle or to fit your specific application.  Many Hot Rod or Later model vehicle owners and fabricators will prefer this type of system over others due to the cost savings and OEM fitment.  Most universal kits include a completely separate shock and suspension system meaning the shock is not built into or connected in any way to the bag (example would be an air strut). Instead universal systems will adapt easily to late model axles or coil spring cups.  This way the fabricator can use pre-existing hardware to get the installation done.   Coil spring cups will make an easy adaption from your OEM coils springs and allow the installer to mount the new air spring in place, keep in mind that most of the modifications done to a vehicle with a universal air suspension kit cannot be undone without having to hack away at your old modifications.

Some of the newer late models will also work with these universal air kits, as the design is still the same on many vehicles today.  For instance some of the truck line of vehicles, Chevy, Dodge, Ford models still use this coil spring and axle brackets..

These kits are a great way to save cash and get a quality installation assuming your welder is up to par!  LOL
