I had a JCPenney steel jack for 30 years and decided I needed an aluminum jack. Bought a HF 2 ton that lasted less than a week, then "stepped up" to a Sears 3 ton that would barely lift the front of my Dakota. It lasted a year and a half before it dumped my truck while doing a release and damaged the hood. After being thoroughly disappointed with the aluminum junk, I'm back to NAPA steel jack. And it can be rebuilt too...
