4 link vs 3 link

[vdubman]

im just wondering what everyone perfers 3 link or 4 link and why any help thanks

[smallblock500]

wow i was just logged on to post this same question lol.

[5150bronco]

there are lots of write ups. just search, really it is down to pref. what you are trying to accomplish.

[Dynamic^Cipher]

I prefer 4 link. With shafts I find that 4 link in the rear allows more adjustability to eliminate some torque twist.

I don't see many 1:1's with 3 link either.

in fullsized, guys that run three links arent concerned with drivability at all, just performace. if your talking about the ax-10 stock setup. it's already a four-link, called a wish-bone 4-link. wish-bone setup will give more flex but the down fall is torque twist. triangulated 4-link gives less torque twist and less on the flexability side. double triangulated is the way to go with great flex and little torque twist. catch 22, pick your poison.

thanks for explaining. so....., sounds like minimizing torque twist would be a good poison..... so, the triangulated would be the best.

i have internal springs in rear with softer springs in front to help reduce torque twist, but have the wish bone 3-link though. so..., what to do...lol

I have been running the wishbone up front and 4 link in the rear. Both double triangulated. It seems to be a great setup on my rig. I would start there and if need be you can always go 4 link up front too.

i'm running triangulated in the front and wish bone in the rear. good on flex and minimal torque twist. you'll figure it out.

thanks for the input. you are running what setup? i will try that too. not tried yet so i will see and report. i am running a.x.

Actually the way to get rid of torque twist in my experiences is to triangulate lower arms and parallel 4 link uppers. And lengthen the uppers more.

Really? That is interesting......, I know crawlers are diff than full size, but what is your theory behind this? If any.....

thanks for the input, i will have to try that out!

I lengthen the uppers 4link them and leave them triangulated. and parallel the lowersno torque twist here

Yes you can just lengthen them and it pretty much eliminates it but I also had to lower the ride height to still use 3 link. Also when I went to parallel the car side hills better and is just way more stable all around.

[Mortimer Snerd]

You aren't going to find a consistent opinion. I'd tinker and see what works for your terrain and driving style. I'm running a dual triangulated link setup.

by paralleling the lowers....., you mean make them parallel to what?

thanks.

parallel to eachother?
how about some picture examples of triangulated, double triangulated, wishbone, 3 and 4 link set ups

there are so many threads here and people that better understand than I...

parallell to the ground is my understanding.

I'd tend to agree with most. You won't find a direct answer to your question. It's all preference. I run a double triagulated 4 link. But if you are going to run a 3 link make sure you use aluminum Y's the plastic break easily.
