Question Air-Bag It?? Better Suspension What Works??

Looking for proven suspension mods for my 1985 C-30 single cab dually axle ramp truck. Weight with no vehicle in tow 8140 lbs. The Firestone R4Tech Air Suspension appeared to be ahead of it's time in design and function but costly is no longer manufactured. (http://www.trailerlife.com/trailer-h...sion-system-2/)

Looking for idea's for real working improved suspension upgrades front and rear specifically for square body chevy c-30 one ton dually axle 1985. Anyone have a custom built suspension willing to share their design??

I used an old Ride Tech HD 4-bar set-up w/sleeve style bags in place of the leaf set-up. Night & day difference in ride quality + dropped the truck 8+ inches after my tweaks.

They currently offer a universal HD 4-bar kit that's weld-on.

Building a small, high rpm engine with the perfect bore, stroke and rod ratio is very impressive.
It's like a highly skilled Morrocan sword fighter with a Damascus Steel Scimitar.....

Cubic inches is like Indiana Jones with a cheap pistol.
