one link suspension??

Can you engineer a one link to have the right anti squat or roll axis angle?

Sure, but it will always have disadvantages compared to a 4 link. A one link suspension is closer to a radius arm setup than it is to a 4 link.

BTW there really aren't any "right" numbers for anti-squat, there's lots of debate about that. Most shoot for 80-100%
 
I have just started to read all the tech articles on 3 and 4 link set ups, they are pretty interesting and damn confusing all at the same time. Anything other than leafs are pretty interesting to learn about.

I agree with ya there, I usually get in over my head :o

I would think you would want a lot less anti-squat (or anti-dive) than that if you are going to be doing any medium to high speed stuff. IIRC, too much anti-squat or anti-dive can cause that end of the car to stiffen up and jack up over a series of high speed bumps.

But I'm just a nOOb at this multilink stuff too - it is very interesting and confusing at the same time. I can see that as an advantage of a "one-link" - much less to screw up. :D Having said that, I would prefer to go triangulated 4-link myself if I ever win the lottery and switch to coilovers. Another problem with a "one-link" is that you have very little control over pinion angle. I don't think you could ever run one in the front, cause your caster would change too much.
 
The whole linked suspension intrigues me. Reading all these threads about 4-linking and now this. It's all too much for my brain to absorb but i'm trying. I understand how it works...there are just parts of the fabrication and stuf that i don't quite understand.

I'd really like to do both the 1 and the 4-link just to see the advantages and disadvantages of both. Seeing as how i'm not a millionaire (hell i'm hardly a hundredaire) it'll be way in the future before that'll happen though

I'd really just like to see pics or better yet video to see both in action. :D
 
I totally agree. Maybe if I saw the process of creating a 3 o 4 link I would understand it better.

The one link is easier for me to visualize and understand.

I was talking about rock crawling (including full throttle attempts at obstacles). Drag racing and pre-runners are a totally different deal and have a totally different suspension.

Exactly, its less to screw up because there is less to it. Most people that can't design a 4 link are drawn to this because its easier to setup but will end up with lesser results.[/quote]

You don't have to use coilovers with a 4 link, I'm doing a 1/4 elliptic which uses very inexpensive shocks/springs.
 
Hmmm I just read through blazerbaltos 4 link write up and now I am very intrigued! If only I had the knowledge, money and tools to do it :doah:.

Gotcha :waytogo:

Agreed.

But in the unlikely event that I ever have the time/$$$/skilz to do it, I'd want to go with coilovers.

I'm going to link the rear of my rig pretty soon and I have ~$800 budgeted for it (links, joints, brackets, truss, etc.). Going with 1/4 elliptic and some kind of cheaper shock saves a lot of money and leaves you with a lot of tunability.

There is no doubt that coilovers are better and more tunable but at $500 a corner I'll pass on them for now.

One thing that always confused me about 1/4 elliptic was how do you know what springs to go with? 1-ton packs cut down?

It could be pretty much anything, its mostly based on how much weight is on the rear of the truck.

That's one of the great things about a 1/4 elliptic, its very tunable (via bumpstops and/or adding or removing leaves).

56's and 64's are pretty popular for 1/4 elliptic setups.

Cool! well I guess when I'm ready to link the rear I already got the springs for it. What springs are you going with?
