No I have not.
But the beauty of the F-150 is that you can add a leaf to prevent spring wrap. Which is what the traction bars and ladder bars are designed to do.
I have a 9 inch rearend that spins more than grabs traction. But you 6 cylinder guys wouldn't know about that!

ladder bars will give alot better traction than just adding a leaf.
They plant the weight to the tires forcing them down. Watching a drag car with ladder bars on a chasis dyno will show you , the suspension in the back will jolt up when axle tourque increases.
Traction bars mainly just prevent the axle wrap.
But if I am unable to get a ladderbar setup, ill just go with traction bars.
Ladder bars are really not a good choice for a street vehicle because of the drastic change in pinnion angle caused by suspensiot travel. Ladder bars also cause the distance between the transmission and rearend to change greatly and quickly. Most people don't realize that when you use ladder bars you also have to install a floater kit to allow the axle housing to move back and forth on the leaf springs.
In my opinion traction bars are a much better choice because they allow for normal operation of your suspension but also do an extremly good job of controlling axle wrap/wheel hop.

Ladder bars can be very effective, but for a truck they must be setup a bit differantly than those on drag cars, to avoid just the sort of troubles the last poster mentioned. Be prepared for them to cost a lot more than car ladders. If fitted with a swiveling link on the front ends of the bars, the spring travel will not be affected. Drag cars have a floating cage on the axle, this would be do-able but a pain on a truck. The front joint on a good truck bar looks sort of like a spring shackle with swivels in it. The frame needs to have a place added for these to mount to, and you have to mount the back ends to the axle somehow. Look at some four wheel drive truck magazines and you'll see some of these. DF
"Suretrack" bars, J.C. Whitless, about $60.00 (?). they go over the top of the axle/springs and extend to the front eye perch area. Work like half a four link. Work fine.
