Didn't rear links come with your Metal Cloak lift kit or did you do a franken-build? I would have thought if you bought the suspension kit from MC the proper rear links would be included.

Does the length of the links affect body roll? I would have thought they can cause the sway bar to pretzel if too short but it isn't like he is running disconnected. Just curious.

Franken-build. I started with a 4" Rough Country lift, but that had to go. I've been piecing together a gamechanger kit since then

Torque = Force x distance

Physics comes into play once again. Take two examples. The first where the sway bar link and the sway bar arm are exactly 90 degrees / perpendicular to one another. Visualize the force vector moving up along that sway bar link from the **outside tires ** as you make a right turn. That's 100% force being applied along the x-axis and applied to the lever arm (this case the sway bar arm) which is the most optimum application of force to that bar/lever.

Now take the next example where the sway bar link is pointed 45 degrees downward because your links are too short. Now visualize the force vectors in that system that are now in play. Since upward force is now being applied at an angle and you now have X & Y component vectors being applied, you've decreased the magnitude of the force being applied upward along the x-axis which is the one most needed to counter compression in a turn.

This second case is actually more simplified because for simplicity's sake I'm keeping the sway bar arm still perfectly lined along the Y-axis but the concept still doesn't change...

I would think a sway bar at 45* would be stiffer than 90* would it not? Less leverage.

No. You want more leverage to counter body-roll, not less.
