          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.

          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.
