XRay X4 CFF2 Rear Lower Arm Short Medium XR303184-M

The XRay X4 CFF2 Rear Lower Arm - Short - Medium - Right, part number XR303184-M, is a short, medium rear lower suspension arm for the right side of the car. It is intended for the X4 CFF2 chassis and uses CFF2 carbon fibre with composite plastic detailing.

Compared with the long arm, this short version gives the chassis more roll and increases initial steering. It is recommended for tight or technical tracks, particularly where low traction makes additional steering useful. The more aggressive response can improve steering in these conditions, although the car may be more difficult to drive.

The arm is designed to provide suspension rigidity while remaining light and durable. Its revised suspension geometry places the shocks further outboard to support traction and steering in different conditions. A dedicated pivot-ball design allows straightforward assembly while maintaining reliable operation. XRay recommends using this arm with the #301028 Chassis Hudy Spring Steel 1.2mm Short, medium hardness.
