The XRAY 342033 Aluminum Upper Arm Holder Right is engineered for the RX8.3 chassis and machined from Swiss 7075 T6 aluminium to withstand hard use while keeping steering response consistent. Coupled with the redesigned aluminium bulkheads it helps control chassis flex for more predictable corner performance.
The part uses a single screw to the front upper clamp and two screws to the radio plate, giving straightforward installation. Using XRAY's Multi-Flex philosophy you can remove one radio plate screw to add compliance, allowing quick tuning of caster and entry grip on different track conditions.
