What kind of heim joints for 4-Link
 

Hi guys, I am planning on bilding a home made 4 link on my 69 camaro.
What kind of heim joints do you recommend ? I see a lot of junk on the web, what is the minimal load capacity I should use ?
I am bilding a 600+ HP street, strip / track car.
Thanks

They sell these types of ends - and could tell you what ends you'll need for which parts of your suspension.

I plan on using AFCO chromoly rod ends. What loads are in you links? Are the links design to be in only compression tension, no bending? If so you can look up the specs on the rod ends. Look to see if the radial loading is within your requirements.

Aurora makes the best in my opinion.

Good deals can be found here. I have not checked their quality.

currie and spohn make some good ones. if you want a traditional heim with no urethane, then nothing beats the qa1 xm series. moly constuction, teflon lined. its what the rock crawler guys use. id look into the currie johnny joint though.

Pretty much the best ones are gonna be the QA1 X series. They are XM for the males and XF for the females.

The 5x8"x5/8" are the standard. Many companies sell QA1 ends unlabeled, for more money, but they are the same parts. I have 16 of them on my car right now.

I just put a set of 8 of them on my 4-link car this weekend. I also used some seals-it caps.

The ends are 20 bucks a piece. Caps are a buck or two each and you need 16.

But there isnt a stronger rod end than the QA1. JR

Rod Ends
 

I use Aurora High Perfromance PRM/PRB series rod ends. They have a 4340 steel body, Stainless Steel race, 52100 heat treated ball, and a bonded PTFE lining. They are very tight and operate smoothly, and I think they are among the strongest available on the market -- just a little pricy ($60-$70 each), but you get what you pay for.

Aurora or FK are top notch. Aurora is mil spec'd, vs. FK is built to mil spec but not tested/certified for military. A huge majority of the NASCAR/IRL/Off Road guys run FK.

I may be wrong, but did QA1 used to be made offshore or still are?

The QA1 rod ends are exactly like the Aurora. Same material, same specs, everything. Cept they are 20 bucks each. Even crazier, they are called the same thing. The XM series. Almost like they were made by the same company. Oh, the QA1 end is rated at 17,955 Lbs and the Aurora end is 16,565 Lbs. But Im sure that is just marketing issues LOL JR

And I didnt even notice till now. They both use Thomasnet for their online catalog. Looking more and more like they are connected somehow...
