I always buy the biggest JackStands I can and I back them up as much as possible. Sometiems I will use 4 total in the Car front.
You have to be careful because I am not sure import Steel is as safe as US Steel. My Heinz Werner Jack has lasted 30 years with one rebuild of the seals, but I dont think many of the newer jacks you buy can do that.
Last year a man in my area was killed in his garage underneath incorrect Jackstands.
I really wish i could specify and recommend a Brand, but I cant since many more Stands are made off shore out of imported steel of unspecified quality. The only rule I can mention is use four in the front if you are doing a transmission or something Major. Loads can shift!
