As long as you have the good concrete blocks. There's various grades, some not as sturdy as othersMy concrete blocks and 2x4s haven't let me down yet!
Yeah, I was thinking they may have been rebranded "Michelin" since I got them with the Michelin floor jack you can barely see in the background but, who knows?
