The overall quality is very nice and appears to be well-made. Upon removing the old barbell you can see just what a difference there is between the old one and this new one. Make sure to apply a small amount of oil to the O-ring so that it slides in easily. Make sure not to press it in too far, for the most part you really can’t as long as you press it to where it’s pretty much flush with The back of the block.Will be purchasing more for two more motors being built.
