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.

• Kit includes 
• 2 of Front Upper Control Arm Bump Stops
• 2 of Flat Washers (3/8 inch)
• 2 of Nylon Lock Nuts (3/8-16)

Why Urethane?
Production vehicles are built using rubber bushings in control arms, strut arms, leaf springs, body mounts, motor mounts, transmission mounts, sway bars and shocks. Additionally, rubber components can be found as coil spring pads, leaf spring pads and suspension bump stops. While rubber components offer a soft side, for typical driving conditions, they tend to deteriorate rapidly from exposure to the elements. This contributes to premature component failure, resulting in a “spongy” ride and loss of performance handling. Urethane is impervious to gas and oil and will not rot and is stronger than rubber.

Improved Handling and Performance
Due to the firmness of our specially formulated urethane, vehicle owners that have upgraded to Total Kits and Components have experienced better handling, cornering and a firmer suspension feel. American Performance urethane bushings are a “must” upgrade for High-Performance vehicles where improved performance and durability are desired. 

Installation Made Easy
American Performance urethane products are made to exact specifications and are direct replacements for original rubber bushings and components. No special tools are required, standard tools and equipment replace factory units.

Shells/Sleeves
American Performance has a complete shell program for most popular applications. Many of our control arm bushing kits come complete with new shells. However, in some applications, the original metal shells will be needed to be reused. 

Rubber Bushings?
American Performance offers complete rubber bushing alternatives if you prefer original equipment quality and ride performance.
