Tired of playing around with stacked 4x4s and other items to make my jacks tall enough for trucks and Jeeps. Making extensions for me and my friend. Machined and welded. Here are the machined extensions. These are 8-1/2" and 4" extensions. Use this information at your own risk

Nice job! I’ve got at least 30ft of 2” solid, I’m going have to copy that idea bud, thanks.
I am sure 2" will work. Look at the bottom of your saddles and make sure they don't have a protruding weld around the saddle pin. My Napa has a smooth transition from the bottom to the pin. You will need to cut a relief in the extension or find a different saddle. The round stock I used started out at 3-1/4" OD.

I understand the stability aspect of it and can find a suitable solution. It's just that I bought several bars years ago for a project that I needed a stable axle. Every once in a while I need some small pieces but still have a bunch of it just laying around, might as well do something constructive with a few feet of it. But thanks for the concern.

Nice work. I'm about to make something like this to improve safety when lifting solid axle cars with my bridge jack. I just need to find a little time to get out to the shop.

Very cool. I don't know though, it would probably make me work a little slower than having the impending doom of that wobbly 2x4 wedged under the trailer hitch.

Nice work! I've got plans to make a couple extensions as well. It just hasn't been high on the priority list yet.

That's awesome, I've been thinking about building something similar to lift the front of my twin-I beam F-150.
