2 link, 3 link, 4 link...

[Bumbo]

Not really a 4Runner specific question I guess, but in general terms...

When people talking about modified suspension and linking the front or rear... what are they referring to?

Does it change when talking about trucks to SUVs?

I've been watching videos of solid axle crawlers with a lot of articulation, along with buggy/trophy truck type videos and so many varying different types of suspension setups and I am just trying to understand more of the technical pros/cons and challenges that go with each when it relates to what we own and how more custom modifications can be applied...

I know this can generally enter the world of completely custom, but I just want to educate myself before jumping down a rabbit hole I don't want to be in.

The link connects some part of suspension from one side to the other via the sway bar. The links sold by [MENTION=98153]MStudt[/MENTION] are beefier than OEM as well as longer to accommodate longer than OEM travel. He also offers a set that have an easier capacity to disconnect for off road use. Allowing you to tie the away bar out of the way (zip tie) have your weekend fun, then reconnect before getting back on the road.

The link numbers refer to the specific solid/live axle suspension setup. Stock setup for our trucks is a 4 link which refers to the number of linkages that connect the rear axle to the frame.

• 2 lower links + 2 upper links = 4 links, panhard bar isn't included.

A 3 link removes one of the upper links in favor of a stronger single upper link, which I guess can give more travel.

• 2 lower links + 1 upper link = 3 links, panhard bar isn't included.

This is my understanding, someone please correct me if I'm wrong. Check out google images for pictures regarding the setups.
