uses the same hydraulic core unit as the regular 3 ton unit, the only differences are 2 magnets thrown in the reservoir and the pump cylinders utilize Ucups versus Oring/backup and some different frame work, Oh.... And it’s Yellow. Lol
I do have concerns with the cartridge valve system, and even with the small sample size of GJ I have fielded no less than 10 emails/pm’s regarding missed strokes and poor performance, both are by products of Air entering the valve system. The Oring/shell on the Main Ram is a blatant attempt for HF to limit the longevity of the jack, Why go to extremes to market it as a professional jack and then skimp (pennies) on the Main Ram seal.. Silly.
