Arrow Shannon Campbell Racing Trailing Arms!

These have been a long time coming but they were well worth the wait!

Shannon Campbell and I have known each other for 8 or 9 years now and had spoken often about how we might be able to work together. These are the first thing we have developed because of that.

2 Years ago Garett (Ruffstuff CEO) spent a week with the Campbells in Gilbert thinking, talking, and drawing CAD up of directions we might go. After many prototypes and design decisions we are ready to release these Trailing Arms. These are the same trailing arms Bailey Campbell took 5th place at KOH on last year, they are not some untested junk we want you to test for us, these are the real thing and we are now making them for you!


Wayland, Bailey, Shannon, & Dan at Offroad Expo

When you look at them you first admire the welds. Shannon was very particular about letting just anyone weld these. We only allow 4 of our 8 welders to do the work and they are all excellent welders.

Next you look to the attention to detail in the reinforcment. Right down to the to the RuffStuff fixit weld washers the shock eye holes are strengthened with.

Then we can talk about the reinforcements you cannot see. The internal plate with multiple bends that give amazing torsional rigidity with very little added weight.

One of the most interesting & important items is the Aluminum bar pressed inside the leading section of tubing. It not only fills the space to prevent deformation but cures an ill many have had in the past of tearing out bungs on extreme impacts. The bung is extra long, then the end of the bar is threaded into it & plug welded so they become 1 piece that is not going to pull out.





Finally I should mention that the arm itself is 4130 Chromoloy and the aluminum is 6061. The tubing is 1.75" in diameter and they come with a 2 - 1" uniballs and 2 - 1.25" heim joints. They are 40-40.5" long & Overall they weigh in at 30lbs each which is way lighter that most. We only sell these fully welded so you can be sure they are the best arm possible.

These are the first in what we hope will become a long series of items from the Campbell Racing Garage, Shannon and Nick and pretty badass builders! Stand by to see what else we come up with

You might not want to answer this, but...

The aluminum is threaded into the bung, which is welded to the tube. You say the aluminum will keep the bung from ripping out. So what's holding the aluminum in that will keep it from ripping out of the tube when the bung does??

The aluminum was not just slipped into the tube, it is pressed into the tube and is about 20" into it. Also the bung is overlength and plug welded also. Nothing is impossible but I can say this makes it a hell of a lot less likely to happen... Finally, when you get them into use every impact makes the tube tighter on the aluminum and if you are not having impacts you are not trying hard enough

Makes sense!! I saw it said pressed but I guess you guys probably make it fit pretty tight!

Can you heat treat them with the aluminum inside the arms? It's an attractive price for well built arms. I need to do some measuring on mine to see how close they are. Also, are the shocks mounted below the center line, or above?

First, the shocks are below the centerline by over an inch, I believe 1.5" but I would have to refer to the drawings to be sure.

On the heat treating with the aluminum in place. I believe the HT point for 4130 is higher than the melting point of 6061 so unless you could devise a way to keep the aluminum in place during the HT I don't think so.
