Not sure on the brand, they came with the truck when I bought it. They come with good poly bushings, no need to replace. The ride was good, not too stiff or soft. I didn't run a sway bar but have 3/4ton springs in the rear of my Blazer. Here is a picture of it with the springs on and ~32" tires. I think they are ~2.5", I'd be lying if I said I was positive. Local pickup preferred. I'll take a 12 pack of Dos Equis, or $30
