The XRAY 342033 Aluminum Upper Arm Holder Right is intended for the RX8.3 chassis and is manufactured from Swiss 7075 T6 aluminium to give reliable stiffness and longevity. Matched with the aluminium bulkheads it helps shape chassis flex for crisper turn in and steadier mid corner behaviour.
The unit attaches with a single screw to the front upper clamp and two screws to the radio plate, offering clear tuning points. As part of XRAY's Multi-Flex system you can remove one of the radio plate screws to increase compliance, enabling adjustments to caster and cornering feel without replacing parts.
