designed drop trailing arms
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 |

Re: designed drop trailing arms
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?

Re: designed drop trailing arms
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.

Re: designed drop trailing arms
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.

Re: designed drop trailing arms

Re: designed drop trailing arms
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.

Re: designed drop trailing arms
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?

Re: designed drop trailing arms
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..... LockDoc

Re: designed drop trailing arms
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.

Re: designed drop trailing arms
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.

Re: designed drop trailing arms
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.
