My friend has the Afco adjusters and it looked like they were painted black, while the Ladrums are bare metal.

Is there any other difference other than prices

I beleive afco's are powder coated. Both serve the same purposes.

I have the Afco’s on my 73 and was told by Dave Pozzi that the Afco’s have the largest center hole to allow a larger dia. shock than the Ladrums adjuster.
