What kind of heim joints for 4-Link

[WSSix]

How timely this post is. I was wondering around dreaming about what I want to do with my TA when I have time. I'm poor right now and the cost of the DSE Qlink is hard for me to envision I would accept. So I was thinking I'd just build my own 4 link when the time comes. Only problem I was having was is the swivel link rods found in the Qlink that good? If not what rod ends would I use, rod or JJ? Now I know. I still wonder if the Qlink is really that good or can you still do great without the swivel links?

Thanks for the education guys

ballistic fab just replaced their lower qa1 line with the midwest control stuff. if it was for sway bar end links its one thing, but for critical suspension points i wouldnt want to be the guinea pig.

i used jj's for mine after listening to mark explain why they were so much better. if you saw one you would understand why they are so damn strong.

Here is some technical information from the QA1 site that you might find useful. The first link describes how a rod end's ultimate static load is computed -- it is the lowest of three areas: race material compression strength, rod end head strength, or shank strength. The second link provides a cross-reference of various QA1 rod ends to other manufacturers (Aurora, Spherco, etc) which might be useful when comparing prices.

I have attached a shot of my garage-built 4-link for an independant suspension. It uses a C-4 Corvette upright with Woodward swedged tubes and Aurora rod ends (3/4 in.).

Pappy-

You need to start a build thread of the 'Vette. People here would flip out on it. Hope all is well in Lost Wages!

Thanks for the good info guys. I've always heard heim joints need to be replaced every couple years and were bad for nvh but I never knew the jj had better longevity and less nvh. Can any one explain the differences between them or point me to a good website?

Edit: Never mind, I found them on Currie's website lol. I never knew there was urethane in a johnny joint, pretty cool design. There's a video on Currie's site http://www.currieenterprises.com/ces...nnyjoints.aspx
