Team Associated has released a new, optional rear shock tower for the B6. This tower is taller than the stock tower, allowing you to equip your ride with the longer, higher-capacity 31mm shocks (the same shocks available on the B5 series). This setup is designed for bumpy or loose tracks and is a direct bolt on item.
