When needing to change a tire or work under our vehicles we humans reach for a trusty jack. The standard jack in your trunk or mounted behind the seat of your truck works fine 99% of the time. But what happens when the vehicle in need of repair has a lifted suspension, raising the frame in relation to the ground and making the stock jack now too short?

Off-Road enthusiast [am4x4] had that problem and came up with a neat solution. He made a lift kit for a roll-around mechanics jack! He started with a 1.5 ton jack from Harbor Freight. This jack had 2 small casters in the rear and one wide roller in the front. This combination works great on concrete but [am4x4] needed this to work out in the dirt so a few mods were in order.

First the front roller was scrapped and replaced by two large 8 inch diameter tires. To get these to fit the bolt holes for the roller were enlarged to the same diameter as the wheel bearings. A new solid axle was then made from 5/8 inch solid rod. Those may look like pneumatic tires but they are actually solid rubber and only cost $6 each, also from Harbor Freight. These tires not only raise the jack up several inches but also increase the surface area contacting the ground. This better distributes the weight of the vehicle and prevents the jack from pushing itself into the ground.

In the back, the small stock casters were removed and replaced with larger, heavier duty ones. Even with the larger casters, the jack leans rearward. [am4x4] plans on making an extension to level the jack out but for now, it works well and is definitely a conversation piece at the off-road get togethers.
