Right now we are working on the 3 link rear, and I am having trouble deciding what size tubing and rod ends I need for the lower links.

HRPWorld.com sells 1.125 chrome molly links for 5/8" - 18 rod ends with tig weld tubing adapters. The rod ends I am thinking of using, use a 5/8" bolt. I will be using this for the upper link.

Will this be strong enough for the Lowers? Or should I use 3/4" bolt with 3/4" rod ends and bigger tubing for the link?

Thanks,
Jon

Jon, 4130 rod ends will be strong enough.BUT rod ends will REAL NOISEY.They will bang and clank. Look at using some rubber or delrin syle bushings.My rear suspension is rod ends and it drives up the wall on a long drive.My new camaro project is going to have some poly bushing in the front and a johnny joint in the rear of the bars. call and we will talk.785.594.7481Scott.

Jon; The bolts in the 3 link on my camaro are also 5/8 for the upper and lower.The 4130 moly rod ends are lined and are not as nosiey.also my car has no sound deadern & interior.That makes it loauder than your car would be.I used 1.250x.095 4130 tube for my 3 link tubes.The 1.125 will work if the wall thickness of the tube is not to thin.

[Jtomas801]

Thanks for the info Scott! I will see about the wall thickness from HRP if it is too thin, I just might have to call you about making up some links for me.

Do you tig the adapters on or do you tap the tubing and just thread the rod end in?

Over the weekend I was at a friends house and he had some left over circle track stuff. I found this cool adjustable panhard bar mount that gives you about 4" of up/down adjustment by turning the bolt on the end. I was thinking about running it for the chassis side of the upper link. This way I will have infinite adjustment with in the 4" range, instead of raising it in 1" increments.

I have been playing around with two different programs to configure the 3 link and I think I got it to where I want it for now. Hopefully we can finish making the brackets and get the welded in this weekend.

Thanks,
Jon

Jon; I get my my threaded tube ends from McMaster Carr.com about $7.00 each.Then I tig weld then ends w/ 1 rosette weld per end.Call me and I will walk you though the steps.

hey cool build! check this site http://www.suicidedoors.com/catalog/...-link-bushings ... they have some really beefy bushings for your 3link.

We haven't been working on the car that much, but Sunday we got some of the three link brackets made. The LCA frame mounts are now done and welded to the cross member, the axle LCA mounts are fully welded together and tacked to the rear end housing for now, the axle UCA mount is made and tacked to the housing.





The cross member is almost done, just waiting on some material to build the upper 3rd link mount.


Here is the start of the panhard bar mount, it is slotted and has 4" of adjust ability. It will be mounted on the passenger side of the axle.


All the brackets will get more bracing after every thing is mocked up.

Scott, I will give you a call before we start making the links. I found the tubing adapters on McMaster-Carr, thanks for the tip. I decided to go with PTFE lined 5/8" rod ends. I was thinking about going with DOM 1.25" .120" wall tubing instead of 4130, as we don't have a tig welder. But I also noticed the tubing adapters are 4130, can these be MIG welded?

Thanks,
Jon

[coolwelder62]

Jon;
You can mig weld the tube adapter's. Just make sure you drill a 5/16 hole about a 3/8 of an inch from the end of the tube and rosette weld the tube end also.Mild steel will work for the 3 link tube's.Look's great.

[Jtomas801]

Well this weekend we got the 3 link cross member done and tacked in the car. So far so good, we just have to double check our measurements before welding it in place.





I hope to get started working on building the links and the upper coil over panhard bar cross member.

Thanks,
Jon
