Ok, so here it is re-building a car currently has a 3 link, is it worth replacing with 4 link??
Driven both types , didn't spend enough time behind the wheel of the 4 link truck to notice any difference .

So can someone who knows explain the real differences ??
Pros and cons of both??

If you are working within the confines of stock frame rails, a 3 link will give you more angle in the top links (as viewed from the top) vs a 4 link, resulting in more strength in side load. That single rear link joint will be under more stress than a single link joint on a 4-link so it needs to be sized and built to handle the higher loads. So 3 link can have a packaging advantage.

I don't know if there is much difference in handling between 3 and 4 link trucks, all else being equal. I've owned both and can not point to a bad handling characteristic on either.

After reading your recent response on springs, the shocks that you referenced have me doubting myself on what you are running. OK Mystery Man---- we need pics !!

Upper links have too much stress from the side loads and that stress harms the 3 links quite often, 3 links are much harder to fab up and only has 1 joint that wears out fast, you have to weld it to the arm from coming loss and the bungs wants to rip out.
