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. For improved bushing life, the latest materials were used, and a high-precision spherical bearing on the trailing arm side was utilized to reduce twist at the inboard bushing. Even though a second spherical bearing for the inboard pick up point is offered as a racing upgrade, we chose to use only one spherical bearing to minimize unwanted increases in NVH for street use. By using this specific combination of bushings, handling performance and control is improved significantly without compromising NVH or comfort.

All Skunk2 products are carefully planned and designed in-house using the latest computer simulation and modeling techniques, followed by careful testing in controlled laboratory environments using state-of-the-art equipment. Each product is then subjected to rigorous dyno, street, and race track testing to ensure proper performance in the most extreme conditions. For these reasons, top street cars and race cars worldwide rely on Skunk2 products.
