Ultra and Alpha LCA's

Skunk2 Ultra and 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 an 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 pickup 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.
