The big wheel kit converts your jack to roll off road with ease. It comes with zinc plated steel front axle extensions and an aluminum rear axle held with side plates. The Polyolefin big wheels are retained with snap rings and have delrin bushings that are light, super strong and affordable.
Make sure to measure your jack width - scroll down more for specs. -
Older jacks can be mis-labeled or just different than what's currently
available. Harbor Freight is known to change things. Some jacks labeled 2 ton are actually the 2 1/2 ton model, order the kit that matches the width of your jack over the label. More pics coming soon.
