Bump Stops are a critical part of your vehicles suspension - they prevent damaging over-compression and eliminate harsh bottoming of the suspension. Daystars Bump Stops are designed and tested under the most rigorous conditions imaginable to deliver positive stopping power without deflecting. Our EVS Foam Bump Stops are the next generation in bump stop technology. Our EVS Foam stops use a proprietary Microcellular Foam material that provides a true progressive spring rate. Rather than being strictly a limiter, EVS Foam is designed to be an active part of the suspension with a rate that increases as the material compresses. Great for everything from racing to recreational use, the only limitation to our EVS Foam is your imagination!

Finally found bump stops that fit my 1985 Dodge W350. Thanks to 4 Wheel Parts, they took the time to measure their Bump Stops until they found one that would fit. Glenn
