Yokomo B9-RTC-01A RTC Graphite Rear Suspension Arm (53mm-40mm)  [B9-RTC-01A]

Graphite Rear Suspension Arm for BD9 RTC

This is a graphite rear suspension arm designed for the RTC layout of the BD9 series, intended as a like-for-like replacement part for 1/10 electric touring RC cars. The arm maintains the RTC geometry with a 53mm distance between the inner and outer suspension pins and a 40mm shock pivot spacing, matching the original RTC pin locations.

Compatibility is limited to the supported chassis listed below, so verify chassis code before ordering. Installation follows the same mounting points as the stock RTC arm, requiring removal of the existing arm and transfer of any pins or hardware as needed. Check pin fit and retaining clips during assembly to ensure secure operation.

Functionally the graphite arm is used to preserve or restore the RTC suspension geometry, it is suitable for routine maintenance and straightforward tuning swaps where the 53mm/40mm geometry is required, and it works with standard RC suspension pins and shock setups for the listed models.
