After a highway trip between Los Angeles and Bakersfield CA a couple of months ago I noticed that both of my bump stops were gone from the front end of my truck. Looking closer, there was a chunk of rubber remaining at the bottom of each bump stop cup and the rest gone. I looked because there are a couple of pretty good sized dips on the highway that made the front end bottom and the impact just felt wrong. Has anyone had this happen? Ended up installing Timbrens. Easy install and work just fine. They do sit higher than the stock bumps though.
