For sale are brand new rubber bumpers.  I mold them at my extrusion shop using high grade rubber - not some cheap regrind all mixed up.  2.5 inches in diameter and 1 inch tall with a 3/8 hole.  Recessed area for washer (included).  Bumper is solid rubber and not cored out from the rear. 

Feel free to ask questions and look at my other rubber molded parts.

I will combine shipping when buying multiple parts.

Best offers only considered on quantities of 6 or more.  Contact me if you are buying that quantity or more.
