USA manufacturers include Milwaukee Hydraulics ( : Milwaukee 4 Ton Service Jack) I have only seen Shinn Fu put U cups on the main ram of their jacks, which usually makes that part of the jack very durable, they don’t cheap out with the o ring+retainer seal on the main ram. Many Shinn Fu jacks may be advertised having a “Speedy Lift” or ”Magic Lift“ system where there is only one pump in the back. Shinn Fu jacks are also relabeled by a lot of different brand names. Omega is their premium line of imported jacks. Hein Werner is their premium line of mostly “made in USA” jacks.
Their house brands are Hein Werner, Omega, Blackhawk, Banner, Porta Power, and Pro-Lift.
the next biggest manufacturer you’ll see is Shinn Fu America ( Shinn Fu America Homepage - SFA - Hydraulic Lifting Equipment Hydraulic Jacks Stands Dollies). If you’re looking for someone other than Torin.
