I use a 6 ton bottle jack and 6 ton jack stands from Tractor Supply. I had to get the 6 ton stands, the three's just looked whipmy, and if my head is going to be a foot from it under a diesel engine....... yeah, I'm going bigger than necessary. I went with the bottle jack because it's small enough to carry around in my toolbox and it beats the heck out of the stock screw jack.
