They make two of them. This is the shorter one. I think the other is 10" longer. I like it because its lighter than the bushtec. It's all aluminum. My friend has an old bushtech turbo. I found the air suspension system somewhat of a pain. Always had to tweak it depending on the load. I've had mine on the Blue Ridge Pkwy and on some other twisty roads. Never felt it was holding me back in anyway. The only drawback, no vents so condensation forms inside if stored outside. When I kept mine outside I put something under the lid to keep it cracked. They don't come lined with carpeting like the bushtecs. I put some outdoor carpeting on the floor.
