Although these jack stands are not the pin type, I bought a pair of 6-Ton last year from NAPA . The 4 existing ones I had for my cars were not tall enough for our trucks. I got tired of putting stacks of 2x6’s under them to build them up.
I looked on YouTube for demonstrations on how the HF jack stands fail and repeated those same tests on the NAPA stands. They were rock solid so I can recommend these stands.
