Proper Name For These Parts... And Function?

I would search the forums for information on my own, but I do not know what these are called. They were on a 2A I had years ago. I know they go between the axle bumper and the frame. They seem to be designed to be a spacer (maybe their name?) but there might be a proper name for them. I am refering to the cast iron pieces in the photo... one is in place and the other is not.



Along with their name, what is their function? Would it reduce the travel of the axle?

Thanks,

Eric

 

I prefer to use the original Willys nomenclature.
The rubber is a standard item on all willys and is always referred to as an “Axle Bumper”,
The cast iron items are listed under “special equipment and accessories” and are referred to as “axle bumper spacers”. They are associated with options such as a Monroe lift and the rear pto units.

 

I second both of the above.

 

Thanks! This old dog learned something new today!

 

Initially on the 2A they were installed up front when there was a crankshaft mounted hydraulic pump to prevent axle contact with the pump and mount. On later 2As they were installed as standard. With the 3A the frame was re-designed to eliminate the need for the spacer on the front; the frame is physically thicker and "dips down" more so the bumper is all that is needed.
