Prothane Bump Stops
Protect your Suspension
All bump stops are designed to protect your suspension from serious impacts. Some vehicles come with bump stops pre-installed. However, these OE bump stops are usually made of rubber. While rubber is good for absorbing and re-directing impacts, it doesn't last long. Prone to cracking, rotting, and eventually falling away, rubber bump stops will eventually leave your suspension completely exposed. Prothane crafts all of their bump stops with high-quality polyurethane, a material tested and proven to be much more durable and dependable than OE rubber. Once you install Prothane's wear and contamination resistant bump stops, you won't have to worry about your suspension's security again. Plus, Prothane covers all of their bump stops with a lifetime warranty handled in-house here at DST.
