Omega Pro Hydraulic Long Ram Jack - 4 Ton Capacity with Flat Base for Auto Garage Shop, Green (OP400S)

Great product but received it without a handle to use the jack! I called the supplier and they shipped a replacement handle right away!

Lippert instructs us to only jack up the RV by the frame and not the axle. The RV is about 23 in. from the frame to the ground. This required a couple of very thick blocks of wood and a standard bottle jack before I found this jack. Not something I could carry with me easily. I had to make a lift saddle/pad for the jack which is held on with a 1/2 in. Grade 8 bolt. This spreads the load across the frame. I also have a 6 x 6 in. Steel plate to spread the load under the bottom of the jack a bit. I’ve tested the setup and it works. Mainly I’ll use this to service the brakes and bearings (with appropriate jack stands). Like the other reviewer mentions it would be good to have the next size up but it is too tall to work.

Then putting this on the ground, you can’t turn the relief valve far enough to lower the Jack, unless you: - Dig a hole next to the Jack, or - unscrew the screw and remove the knob/handle. I just unscrewed mine, tied the handle to the Jack with a string. It’s like a 12 point socket, so you can turn it, take it off, rotate it, RE-install. Or just put a socket wrench on it. It works. No major complaints.

I've read where others have had some trouble with their Long Jack's but this is an excellent model and works perfectly! (or at least in my case) I'm very happy with my purchase.

Poor design. You can't release hydraulic pressure with jack on ground. Packaging was bad and jack was damaged on delivery.

Very nice for the size
