what are the benifets and the dissadvantages of doing this? and also putting the bags on the bars
DOWNHERE   +1y
Bags on the bars give a higher lift

but more strain on the bags

I doubt there will be any major advantage to triangulating all of your bars other than you might be able to make your angles smaller or less since there are more of them... if that makes sense

Only time I see guys triangulate all 4 bars is on off-road suspensions. Never looked into why they did it that way but I imagine they can squeeze a little more articulation out of them that way.

"usually" the only reason the lower links are angled outward from the frame is to keep the mounting point as wide as possible on the rear end. It doesn't give any extra articulation.Here is my old truck to give you an idea of what I am talking about...

The only major thing that it would affect is roll-steer. The bars would need to be triangulated in opposite directions otherwise you COULD still need to run a pannard bar even though they are triangulated. On a Satchell link, where the lower bars are triangulated, you would still want to triangulate the upper bars a bit in order to dial in a bit of roll-understeer. I am sure in some cases that the off-road guys do it for the same reason, but keep in mind that not every off-road guy understands all of the dynamics that are going on and just build a truck that works cause they've seen it done that way before.

For most of you, worrying about roll-steer and roll-centers is not a concern at all. If you stick close to my suggestion of keepings the bars near parallel to the ground a half travel and running the instant center around the front of the vehicle, you will have very little to worry about reguardless how the bars are triangulated.

hey max could u email me the 4link stuff again. you did once befor but computer crashed.

so if a wishbone was mounted under the axle and the straight bars were put on the top would this be considered a type of satchell link and what are the characteristics of having such a low roll center
