The big wheel kit converts your jack to roll off road with ease. It comes with axle extensions for the front that screw on and use a jam/set screw to hold them in place. The rear axle is held with two aluminum side plates that bolt on. Polyolefin caster wheels with delrin bushings 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 older 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. Some older 3 ton jacks may require drilling new holes in the side plates. More pics coming soon.

-Fits 2 ½ & 3 ton aluminum Pittsburgh Harbor Freight jacks only.
-Axle extenders thread over the front axle. The rear casters are removed and replaced with a bolt on axle.
-Rear axle and side plates are 6061 aluminum.

Wheel options - both are 2" wide
6" - is good for most off-road conditions
8" - rolls easier on the soft stuff, but still needs a skid plate

Optional accessories:
Skid Plate - provides flotation where it needs to be, adds strength to jack
