This sale is for two rubber bumpers. These rubber bottoming cushions fit the frame on Harley-Davidson Softail models 1984-1999. They have 1/4-20 threads that are 3/4" long, and replace Harley- Davidson OEM #11451. The rubber part is 3/4" tall, and prevent the swingarm from hitting the frame. Thanks for looking and be sure to check out my other items for sale. I gladly combine shipping when possible.
