Good replacement for harbor freight cylinder. Pay attention to bleeding process for air operation. Thought it was defective at first. Works nice. So far no leaks, woohoo. I would prefer air controller to be metal instead of plastic.
Worked great! Was so impressed I bought a second one. Shipping was fast and packaging was great. I have been using it for over a year now with no problems would highly recommend for any shop or individual use. Saves me much time from hand pumping.
I wanted to replace the original Ram Jack because it was not holding the arm up but I wanted this one because it has a pneumatic pump to it. I can use my air hose to it and then manually pump the jack up to fine-tune the arm.
If you have a cherry picker you have to have this. One man operation
Is way more easy with this! I’ve looked at a few of these and this was the most reasonable. Smooth and controllable.
