            12 Ton RV Jack Kit

            Joseph Thornell
            Excellent Jack for RV’s

            I use my 12 ton safe jack kit on my 35 foot firth wheel. It has the right fittings, the right weight, and the easiest positive jack stroke!

            Workhorse jack kit

            This is a great compact jack set for a fifth wheel RV trailer. I used it on all 4 wheels to change bearings and wheel seals recently and it performed flawlessly. Ease in use and sturdy once elevated using the saddle attachment with the jack ram support collar. An absolute “must have” for this manned roadside emergencies.

            12 ton safety jack

            The jack is heavy duty, and functions well.

            Excellent Jack

            I purchased the jack to use to lift my 15k pound fifth wheel mainly for repacking wheel bearings. It worked perfectly for my needs. The saddle under the axle provides much confidence that the RV is securely and safely lifted while maintenance is being done.
