This is a pair of aftermarket front upper bump stops for the front shocks on a Vanagon and also Eurovan. These have been discontinued for a while as a new part. They were originally rubber. These new ones are urethane and come with stainless steel sleeves for the top to replace old steel ones. If you are replacing these, you might want to replace your dust covers which are a separate part. We have those available as well.
These are the shorter version that was the stock height for the Carat Vanagon which were slightly lowered. If you have an early Vanagon you will see a slight difference in thickness, but it isn't anything that will effect how they work versus an old and worn out one.
