After 10 years of use, my engine lift failed me. The 2-ton lift cylinder, ram, would no longer operate. I found this Vevor 8-ton, with dual-piston pump for less than I could rebuild my 2-ton ram. The dual piston doubles the lifting speed of the old single-pump ram and though I won't overload the engine lift's 2-ton capacity, the 8-ton cylinder will surely handle the weight better.
