The XRAY 342033 Aluminum Upper Arm Holder Right fits the RX8.3 and is CNC crafted from Swiss 7075 T6 aluminium for durability and predictable behaviour. When paired with the updated aluminium bulkheads it helps balance front end flex for steadier steering inputs and improved on-track consistency.
This holder secures with one screw to the front upper clamp and two screws to the radio plate, providing clear mounting points for setup changes. Following the XRAY Multi-Flex concept you can remove a radio plate screw to increase flexibility and alter caster and entry characteristics without replacing parts.
