XRAY RX8 Upper Arm Holder 7075 Aluminium Upgrade - AM-RX8-342030 by Arrowmax  [AM-RX8-342030]

Upper arm mounting holders for RX8 chassis

This Arrowmax AM-RX8-342030 pair of upper arm holders is machined from 7075 T6 aluminium for use on the XRAY RX8 chassis, supplied as left and right pieces. The precision machining raises stiffness at the upper arm mounting points while keeping overall mass low, helping to cut unwanted flex in the suspension linkages.

Fit these holders where consistent suspension geometry and predictable response are important. They install at the RX8 upper arm positions and act as a solid interface between the arm and the shock tower or upright, so adjustments to springs, dampers, or roll centres produce more immediate changes on track.

Installation notes: parts are intended for the RX8 mounting pattern. During replacement verify alignment with the chassis mounting points and tighten fasteners to the manufacturer's recommended torque settings.

For XRAY RX8 racers wanting a firmer upper arm mount, these machined 7075 aluminium holders provide a direct way to reduce flex and improve suspension feedback during tuning.
