Re: Max Jack's vs quick jacks
Personally, my preference would be the MaxJax (or one of the other similar options that gets even more lift). Haven't used one, so I can't say for sure but that's where I'd lean. I have a Quickjack BL5000 SLX currently and do like it but it's been troublesome. I've had issues with the pump and while customer service has been helpful I don't think I should have had to deal with these problems.
Setup/breakdown time is longer than I'd like with the Quickjack and the frames are HEAVY (which is good for safety, so I'm not complaining). After having lived with these for a while I don't think it'd be much, if any, more hassle to deal with the MaxJax posts. And, the kicker for me is that the MaxJax gets a lot higher.
If you were going to be bringing it to the track or out of the garage then Quickjack is the obvious choice but otherwise I think I'd look to the Maxjax. I likely would have went that option but my slab wasn't thick enough. Eventually I'd like to do some concrete work and get a Maxjax or flush mount scissor.
