Outer Limits 4x4 Board

im coiling the front of my sierra.
im looking into options for the links when i found this.
how will it perfom and from EXPERIENCE what am i expecting from it if i descide to do it that way??
i want to run a 5 link style

they work fairly well, but its really a glorified 3link (radial arm setup)

Still needs a pahnard too.

Pros: Easy to manufacture, easier to clear sump than a 5link

Cons: Lots of stress on the main link (has to resist twist too), pinion angle cycles through some very wack angles

Wouldn't the pinion angles be very similar to that of a regular radius arm setup?

would have thought tri 3 link + panhard would have been a better option than that

....there are so many things wrong in those two pics.......

you guessed it
please explain

In a radius arm setup the axle rotates like its fixed to the ends of the radius arms as the axle moves up and down. That setup will do much the same.

A 3-link + panhard is a very similar setup, except the link which goes from the top of the axle to half way up the lower link instead travels all the way back to a chassis mounted pivot point.

The 3 things that I saw straight away that were a worry was the bird shit weld which currently joins the upper and lower links - I think that will break. The other is that the steering and suspension links look like they have been designed by some drug farked engineer and I'm not sure what that is on, but its a typical shocker that would come from Jeep or something where they forgot to understand stress and fatigue in design. ie, the lower link will probably bend in the middle where the upper link joins - assuming the weld doesn;t break first. who knows it may even bend as it fights against the panhard when articulating. The drag link has a massive bend in it and the brake lines are just waiting to get ripped out. Actually the ball joint on the pitman arm will probably also snap through the thread from having angles forces put through it. Hmmmm as I keep looking, what the go with the bend in the springs from the upper spring retainers.

^^^no more explaining...lolol

The idea is solid, IF that's what you want - just don't let whoever welded that shit together anywhere near your zook...

That one looks left hand drive.

Search Trilink or ylink. Some of the Jeep kits run this setup. That one looks home grown.

It also needs more vertical separation.

that was my MAIN concern about doing it this way
plus the stress it will put on the middle of the lower arm.
yes it is LHD and no the owner will not be working on my car.

i think this is the setup i will do.
im after more movement than a nissan but limited to not as much as a full flexy 5 link set up, if that makes sence

A 3 link + panhard will net you just as much flex as a five link if done properly. The amound of flex you end up with will most likley be decided by spring and shock setup/selection.

Design it with a X link setup as well?

that thought did cross my mind.
but i am still steering more towards 2 lowers, 1 upper and a panhard. just after experiences with different configurations of that

thats a worse idea!

ALL the instability of a 3 link with none of the AS benefits may as well put a radius arm on one side and a single link on the other.

I would change this statement around.
A 3link+ panhard will out flex a five link.

"A well setup five link may net you as much flex as a 3 link + panhard" is how I would have worded it

That is theoretically what this guy has done. It's just not right, looking at them pictures is actually quiet scary!

meh, 6 of one

I do agree, since my first post, I think a 3+panhard is one of the best option, proided you get the set up right and have no sump clearence issues

i think i will be able to set it up and clear the sump comfortably.
having cruiser rears for the lowers and another rod for the upper, the one i got to use is about 70-75% shorter than the lower.
not ideal??
i think they state no less than 80%???
as i said i dont really want it to massive flex in the front and be tippy from loose suspension that is too flexy.

I take it ur not a fan of the X Link; even with a lock out pin?
