has anyone used these?

afco aluminum spring rods. they seem like they would be best used when you are very dialed in on your setup and not something for beginners to use....but has anyone tried them?

I have used them on several locations on several types of suspensions. I thought it was very helpful on the rr top bar of a 4 link before the lr-spring-behind-the-axle days.

We used them back in the early 90's on a Z link set up on the RRB bar.They helped move the rear forward under load for traction. But with today's shock behind and everyone looking for rear steer i don't think they would be very helpful on 4 bar on Z links.
