Tag axle

[Spruce addict]

I would like to build a simple tag axle for a 1/25 scale truck. Can anyone give me some pointer on how to do this.

Thank you

I just cut down springs and/or mounts, use shorter air bags if you want the axle off the ground. I also use plastic tube for a straight axle type. Take a look at the real tag axles on rigs to get an idea too. That will help big time.. Not sure if I helped or made you more confused..

Tag axles come in a large variety designs, if you let us know what kind of project you're planning we might can help more. Rear tags are usually straight. Front tags often "U" in the middle to clear the drive line. If your drive axle has air ride, then you could add a tag with a similar set up making the axle out of rod as Kerry said. Also will it be a lifting tag or not?

Give us an idea of what kind of project you are planning.

Like Brian and I mentioned there are a ton of different applications depending on what room you have, drive line implications, bunk house/cab clearance etc.. If you’re stretching the frame then can/bunk house won’t be an issue. You more than likely be building a steerable tag tag but the search I did brought some up in it. Check out the link and look at the pics, it’ll give you a ton of ideas. Then think of what would work best for what you’re building. Then a lot of times some websites will pick them apart so you can see separate parts to better know how to fab them up.

So is it still going to be a tandem drive with a tag in front of the drives, or single drive with tag? If it is a third front axle, I would make a "U" axle. You can simply bend the axle tube or like this build, the center is box tubing and it is drilled for the axles.

If it is going to be a third axle you can rob the Peterbilt air ride from one of the snap kit for suspension. If there is lots of drive line clearance you can also simply use a straight axle. As far as steerable tags the ones that "I've seen" are lift axles not to say that they don't make non-lifting steers . Even doing a search of non-lifting axles, most of the results that come up are lifting axles. But steer axle is an option that you can simply use a front axle from most any kit. If it is going to be a third axle, I would definitely go air suspension, if not from a snap Peterbilt, then AMT, Revell, or Italeri will work too, or even the old Ertl Transtar air ride.

Another option, moluminum, and GW trucks offers a nice axles with suspension as well.

Just an added note. I had my terminology a little off. Of course if there is one thing that I do well, it is butcher the English language. I found out that tag axles are behind the drives and pusher axles are in front of the drives.

We are looking forward to seeing your project!
