I have never used them. I know that they are made by AIM. I know that you get what you pay for. I know that Slam, Contitech, and the new Air lift Dominator are great bags.
Slams are garbage with their delaminating and abortion bubble problems. Yes these were my bags too Not a friend of a friends.. Just got the new dominators though to try out.
i used aim bags for a while. i quit using them when i took my truck apart to do a bd. never put it back together.i ran 400psi (nitrogen)through them at a cinco de mayo show and they handled great. my valves froze up b4 anything. i haven't really ran any other bags so i cant comment on the ride quality. but i know i drove from minneapolis to indy bash and i thought it was a good ride. i would buy them for the price.
