Hi lift jacks are a love/hate relationship with me. Sure , they can be the Swiss army knife of off roading but they can also bite you if you aren't paying attention. I've been using a modified H1 Hummer scissor jack for a few years now and prefer it over the hi lift. It's easier to stow away, a little lighter but still has some weight to it. I haven't weighed it so I can't give an accurate comparison. The mods I did to it were cut off the loops where the jack handle hooks into and welded a hi-nut from an old set of u bolts. Now I can use an impact on it to speed things up. I also cut off the nub on top of the jack and welded a 1.25" threaded nub from an old rod end. I then welded a matching jamb nut to some 1 3/4" tube and notched it to match size of the axle tube. That give me a couple inches of adjustability should I ever need it.
