double & single triangualed??

what the difference in these two set ups?

Single-triangulated usually offers easier packaging at the expense of ground clearance and a steeper roll axis (more flex steer).

Double-triangulated is harder to fit and usually requires more fabrication and design work, but has better clearance and a flatter roll axis.

Since this sort of applies.....

If one were to do any link set up that does not require a track bar, if it were a steering axle, you could not use conventional steering. Is that correct?

IE, have to use full hydro, rather then steering box with inverted T set up?

but what make them different? just how the mounts are mounted or what? where does the word "single" and "double" come into play?

Double Triangulated: (Two triangles)



Single Triangulated: (One triangle and two lower straight arms)

Correct... no panhard (track bar), no draglink.

swbooking thats the answer i was looking for, thanks!!

whats the benefits of one vs the other?

oviously double is more fab time, but is it worth the extra time spent?

also, am i better off making my own cross member with link mounts, or is the unibody strong enough to old the mounts?

if i go straight to the unibody, im guessing ill need to reinforce it?...

Read my post #2.

I did double-tri on mine. No regrets. You have better ground clearance and better performance overall, at the expense of having to do more fabrication work from the start.

Is it worth it? Depends on what you're going to wheel. Hell, the entire concept of going to a 4-link rear in an XJ may or may not be worth it. Consider this:

- What are you looking to improve over the existing setup?
- What are your biggest complaints with the existing setup?
- What are you looking to be able to do with your XJ?

If the first thing that comes to mind is "more flex", stop thinking about 4-links and either get lockers or learn how to wheel. You can get plenty of articulation out of leaf springs if you set them up properly.

Here's how mine looks underneath:



and a shot that shows the undercarriage ground clearance:



You won't get that with straight lowers, but you can get it with leaf springs.

Needless to say, I'm an advocate of the double-triangulated setup.
