A lot of stuff that I've seen people are running a flex joint on the from side and a rubber bushing on the axle side, just to keep the ride decent, but if that's not a issue, (or money isn't ) go with the flex joint on both ends. I'm starting to plan on my L/A setup and I think I'm going to do a 3 link set-up, the y link stuff seems like it would just hinder flex, but that could just be me. If you use the search tool you can find tons of reading material. Or just google it and usually you can find it. Hope I was at least some help.

They use the big ones for the lower arms and the small one for the upper arm

- Large Flex end uses 9/16" bolt
- Small Flex end uses 7/16" bolt

When I recently made my own short arms I used the biggest Johnny Joints they had (http://www.currieenterprises.com/cestore/product.aspx?id=2629) as I'm planning to upgrade them later to longarms. These joints have a 1 1/4" shaft, so should be plenty strong enough for longarms. I'll be making my own version of the TNT Y-links.

everyone has to learn somewhere tho, thats why he's here asking.
could be worse, could have asked for pictures of homemade long arms instead of searching in the first place.
points for originality tho, I don't think I have seen this question before, or atleast in a long time.

I'm just starting my 3-link and will be using Johnny Joints on both ends. One end will be adjustable.

I might be mistaken, but due to the way a radius setup works, you need rubber joints on all but the body ends of the arms. Notice that neither RE nor TNT uses more than one flex/Johnny Joint per arm and that one sits on the body end. The rubber mounts on the axle ends and the upper arm linking to the main arm are to allow for some "twist" as the axle flexes which is how any radius arm setup works.

While thats true for radius arms,it doesnt apply to a 3 link set-up.

Incorrect. I used TeraFlex Large Ends on the body (crossmember) side of mine. The axle end (lowers) use OEM bushings.

Correct, don't know why I for some reason read Y-link instead of 3-link :looney:
What I said was Johnny Joints on the body side and all the other ones rubber ones. What did you use where the upper arm connects to the lower arm?
