designed drop trailing arms

[casey g]

So I don't have a truck anymore : ( but I still love these trucks. ive designed these trailing arms to drop a truck two inches with out using blocks.

they will be made out of 1/4 steel and have ballistic poly bushings for the front.
I've also designed a new front bracket for the trailing arms to mount to.
I also added a few degrees to help correct the pinion angle

just finished drawing today, let me know what you think.

also a pic of my old truck and my dads pro street 64

front brackets cut out. but I might have to make a few changes

[casey g]

this might be better if it was moved to the suspension forum

That's pretty cool. I really like the rear trailing arm design. Great job! What are you cutting with? CNC Plasma table? I noticed the lead in in the holes. I use a .050" radius lead in on holes on our water jet. Are you willing to share your designs?

[casey g]

The bracket was cut out on a plasma table and its brand new. I was his first customer so he is still fine tuning it. I think im going to have the trailing arms cut out on the laser. as far sharing the plans im going to keep them to myself due to I might try and produce these to sell if they works out.

Suggestion on your front bracket. Ad more material around the bolt hole or ad a doubler. You may see some elongation in the hole over time with that little of material. Set it up with an undersized hole so after bending it can be reamed to size to allow a tight straight bolt fit.

there is actually more material around that hole then a stock bracket. but it is one of the changes I'm thinking about

[mechanicalman]

I don't know what ballistic poly bushings are, and it looks like a heim joint in the picture. Learning op for me thanks in advance if you choose to expand on this.

There is a link to what I'm planning in using

I'd be interested. I'm in the Boise, ID area. Subbed for more info and upcoming pictures. Do you have a 67-72 c10 you can try them on once made?

[JHT67]

Hope this isn't rude to ask, just thinking it'd be neat to see what it looked like, and I have no clue how or where the brackets bolt on. Soooo can you draw up pics of the trailing arms and brackets installed?

Just remember, you have to be a "Premium" member in order to sell them on the board. Also, if this turns into a "for sale" or "I want to buy" thread it will be locked and won't do anyone any good. Just a heads up.....

I personally don't have a truck to try them out on but I do have lots of friends with trucks.

I have a frame in my garage and that's it : )

so I finally ordered the first set to get cut out on the laser today! I Should see my parts on the 20th.
Ive made a few changes to the first design. pretty excited to get started on these. hoping they turn out as cool as I pictured.
when I get the parts I will post some photos.

That sounds great. Glad you are finally getting the project off the ground. Keep us posted....

I have thought about building a pair of them for my future '67 1 ton Dually project, as I plan on putting coils under it.

Drop trailing arms are one step closer! Got the parts off the laser today and had to quick mock one of them up!

[casey g]

One more

[Steve Cole]

That looks awesome!! Good job.

[mechanicalman]

Sweet!

[casey g]

I got the front mounts drilled and tapped today. The Ballistic joints should be here tomorrow. On Saturday I have to fly to Hawaii for work but I should be back home on Monday night. The plan Is to start welding these trailing arms up next week.

[casey g]

Got the ballistic joints yesterday. There huge!

[casey g]

One more with a tv remote to show the size

[tranz am]

Looking good!

Why the fixed poly & not their swivel joints? The thickness/stiffness of the construction of your arms w/the poly bushings are going to have more binding vs OE arms/bushings.

Hey scoti. I understand your concerns. I'm using 3/16 material and not 1/4 like I first said. Also there swivel joints are more then twice the price. All I would have to do is order some swivel joints if these don't workout but I would like to try them first. I'm honestly thinking I'm going to be fine but you could be right.
