Skunk2 Alpha Rear Lower Control Arms are direct replacements for the factory OEM arms, and are ideal for street and race applications. Benchmarking off of our previous LCA design, our goal was to design an arm that was lighter, stronger, and more durable without increased noise, vibration, or harshness (NVH). The inboard bushing features a large tuned durometer elastomeric bushing, that is hard enough for improved handling performance yet compliant enough to minimize unwanted increase in NVH, while the lower shock mount utilizes Delrin bushings for reduced friction and minimal deflection for improved dynamic shock control.
