Default One Link Suspensions

I've searched here and on Pirate and can't seem to come up with the answers I'm looking for.

Everyone seems to hate them. Why?

I understand the anti-squat will be through the roof and that the whole trailer ball thing is ghetto fab, but it seems like a cheap way to get lots of flex and protect the driveshaft.

I've seen several ways to attach the arms to the axle but haven't found one that I really care for. If I try this what would be the best way to attach this?

I plan on using a 1.25" rod end w/ a 1" ball and high misalignment spacers just so no one thinks that I am to ghetto fabulous.

Well, I think you pretty much covered it.

Getting flex, for the sake of flex, isn't really worth anything, at least to me. I've always got PLENTY of flex even in narrow track short wheelbase Jeeps.

The reasons to go to links are generally to get better traction and axle control. Yes, you can typically get more flex, too, but the question is how much you really need.

Same reasons for not running radius arms in the back. Instant center location is terrible. Its really similar to drag race theory, that you want your power to give you traction.

Okay that makes sense, I know drag racing suspension theory so maybe I'll apply that to my Jeep. I guess when looking at it I'm not going to spend that much more on 3 and 4 links than radius arms an 1 link. I was trying to look at it from a budget aspect as opposed to an "engineering" aspect. Thanks for getting my head screwed on straight.

Dont do that.... Drag racers want "bite" on the tires when they stomp on it and that translates to scary handling in our sport. Most of their links, mounts and joints are not strong enough either.

Use examples of proven vehicles with similar setups to the one you are building and apply them where you can.

Like Jesus said, flex doesnt get you anything but body roll and high RTI numbers. You want axle control so you dont have unloading or wheel hop whenever your tires spin or you get bound up.

Whiterhino's jeep has 12" shocks on it and traditional 3&4 links. His jeep will probably make any one link equipped vehicle look silly in any situation but the RTI, even then it'll be more stable.

Yeah I know about the chincy materials used in drag cars. I've been doing some more research on 3 and 4 links and that is definantly the way to go. Looks like I'm going to have to make some more decisions on my frame and other components before I start playing with teh calculators though. Thanks again.
