The XRAY XB8 C-Hub "Medium" Composite Front Lower Suspension Arm is a tuning option for the XB8 2019 series buggies. This C-Hub type suspension arm is molded from a medium composite mixture that is better suited to colder ambient temperatures than the stock "hard" composite parts. The C-hub setup is better suited for short technical tracks & smooth surface conditions. At these track conditions the C-hub suspension offers increased frontward traction as well increased overall traction with enhanced steering. Package includes one suspension arm that can be used in the right or left position.
