It's a totally different set up from the air ride kit. I mean it is hard to make a fourlink very different from any other. I mean the design and fundementals are all the same. The build quality and it's ability to do the job can be vary different from company to company, and the results can vary just as wide from installer to installer. But it is not like they bought an air ride kit then copied it. Their design really limits side to side, and with a double convoluted mounted on the axle at 1:1, there isn't a lot of lift.
And as far as the way they do business, I don't want to write a long post on all the details, but I will tell the most glaring thing... Their shipping poloicy. If you as a customer call and buy a roadgrader kit from them it is $200 in shipping. If I become dealer, it is only $75 shippping. I forget what the % discount I would get as a dealer was, but it wasn't much. The bulk of the profit was in being charged $75 shipping, and charging $200 to the customer. So basically there isn't any money in selling their products, if you don't want to screw the customer on shipping.
They did offer me a sweet set up though. They offered to waive the top level buy-in ($5000), they offered to set up a website, with my company name, and maintain it, and drop ship all orders for me.... All at no cost. I would have done nothing, but rake in the $$$... And probably take phone calls from pissed off customers all day
I have only dealt with aim once, and it wasn't to bad. So I can't really slam them on thier service. But I have seen the parts up close at sema, and the fit and finish just isn't as high as the other suppliers.
