The new Doninators are great bags. I have run ALOT of Airlift bags and I have some issues with the old ones, but they finally fixed the problems with their new Dominators.
The main problem with the old ones wre the stupid crimp fings they used to secure the rubber to the end caps.
They had a tendancy to "pull" or seperate completely from the bag, and the results ususlly sucked...ok always sucked.
Now in Airlifts defense this was USUALLY due to improper installation, but not always.
The other main problem was the bag material itself was made of a real soft rubber. It tended to deform after 6 months- a year of regular (not heavy) wear and tear.
They have fixed these problems with the Dominator. The rubber is much thicker and there are no crimp rings, and they beefed up the inner bump stop.
But that being said, I would not use these bags in an area where space is at a premium. Like if you only have a 1/2" before it rubs on something, only because it will "relax" more than a Slam will. The height you can get out of these bags is phenominal. We put some on my buddies S-10 and with an old Airlift bag on one side, and a new Dominator on the other...same air pressure we gained one inch of lift...pretty sweet!
Give youself space around the bag, and you'll be VERY happy.
