The stock, stamped steel vertical link on the S550 chassis has a tendency to deflect under hard launches and heavy cornering loads, creating unwanted toe change characteristics. Our S550 vertical link is made from Anodized 2024-T351 Aluminum with 5/8" Teflon-lined FK Rod Ends threaded in at each end to prevent any deflection without any significant increase in noise, vibration, or harshness (NVH). Sold as a pair.
