The big wheel kit converts your jack to roll off road with ease. Comes with a new full length front axle that uses aluminum spacers. 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

the new 1½ ton Daytona jack which will NOT work with any of our kits...yet.
