Tamiya 51766 TRF421X D Parts suspension arms x2  [51766]

TRF421X D suspension arms (x2)

This is an RC-scale replacement hop-up consisting of two TRF421X D suspension arms molded in carbon reinforced nylon. The parts match the D-type lower arm geometry used on TRF421-series touring car chassis and are offered as a direct replacement for worn parts or as an upgrade option from the standard TRF421 kit arms.

The molded carbon reinforced nylon balances flex and strength to help maintain predictable suspension response on hot conditions and high-grip or carpet surfaces. Use these arms where improved mid-corner stability or a slightly firmer arm characteristic is preferred compared to original molded nylon arms.

Installation is straightforward on compatible chassis, remove the original D arms and fit these units in the same mounting positions, verifying left/right orientation and free movement of the suspension links and pins after fitting. No additional hardware is required beyond the original mounting components provided with the chassis.
