Designed to fit the axles of Semi-Trucks and trailers up to 6" inches in diameter. The jack pad is made to fit the majority of 20 Ton bottle jacks with rams of 2.0" - 2.204" diameter. The pads low profile design makes it easy to place and maximizes the usable stroke of the jack.

Safe Jack pads for rounded structures increase safety significantly compared to using the jack ram directly against the structure because the pad supports the load over a much wider area. The larger contact area adds stability and decreases the load forces on the lift point. The size and shape of the pad makes the jack far less likely to slip or tip when jacking against a rounded surface.

    Well made

    This is a well made, solid product and a good addition to a screw jack. The jack is safer and more stable when lifting by the axle housing. This fit my Harbor Freight 20 ton jack perfectly using the optional 37M-ESC20 screw collar.
    I will have no hesitation ordering products in the future from Safe Jack.

    6” Lift pad

    The lift pad works as advertised. Your shipping charges are outrageous.

    Freight charges are something we all struggle with. If you feel the freight charges are excessive, call us before placing the order on line. The freight charges are added automatically from a program and it's not always the best rate. Sorry that you felt it was TOO much.
    Excellent product

    This is the perfect edition to your bottle jack. Very sturdy, wide opening holds frame rails and axles safely. Would recommend to anyone!

    Good product ,but could not fit to the 20 Ton air jack purchased from Harbor freight tools .

    I am not an expert on the Harbor Freight Air Hyd. 20 ton jack but looking at the specs for the jack it seems that there must be an extension screw on the ram. If you extend the extension screw and use our ESC-20 Extension Screw Collar, I think it will work. See this video: https://youtu.be/CaXFGksUvTU
