You need to know what you are doing building a 4 link setup under a road going diesel truck. The forces are real and need to be managed or you'll have trouble.

Its hard to get enough side to side axle strength from a triangulated setup if you are towing. That is why the big trucks use pan hard bars.

I wouldn't touch this with a 10 foot pole behind a diesel truck used for towing. Not nearly strong enough.

The rear axle on a diesel truck may have 6,000 pounds on it. With 36 inch tires and grippy pavement, the links on a 4 link system may need to resist 5,000 foot pounds of torque when accelerating or braking.

Here is my build thread. Pics start on about page 3 and you'll need to sign in to see them.
