Air Bag Lift Kits

G'day

I have looked into these air bags for my 2004 Nissan Pathfinder and have some info and also a question
There are 2 brands -- Polyair and Firestone Coil-Rite
The PolyAir is available at an excellent price from USA from several outlets and can be delivered here for less than half local quoted price
Both brands available locally the Firestone a bit more expensive than the Polyair
( But much more expensive than the Polyair from USA )
but the Firestone in my opinon is a better product because of the type of air line used and the way it attaches to airbag fitting

Now the question is I would prefer the Firestone product but at USA prices but cannot find a internet source for the kit
( Australian part no. CR5003 )
For example Truck Springs only stock the Polyair product for the Nissan Pathfinder , same goes for others i contacted
Has anyone bought Firestone Coil_Rite Kits from USA and can pass on details of supplier?

also any feedback on these kits in general may be helpful , a search of old posts was interesting but mostly old info .
