XRay X4 CFF2 Front Lower Arm Short Hard Right XR302184-H

XRay X4 CFF2 Front Lower Arm - Short - Hard - Right, part number XR302184-H, is a short hard-material front lower suspension arm for the X4 CFF2 platform. This right-hand arm uses shorter geometry than the standard long suspension arms, changing the handling balance of the car for more immediate steering response.

The short CFF2™ design allows more chassis roll and increases initial steering, helping the car react more quickly in tight and technical sections. It is also intended to improve steering on technical tracks, where a more responsive front end can assist with direction changes. In high-traction conditions, the shorter geometry helps the car rotate and gives it a freer handling character.

Handling Characteristics

The Hard material reduces suspension arm flex compared with a softer arm, supporting increased rotation and responsiveness. This makes the part suitable for setups where reduced arm movement and sharper reactions are required. The handling effect comes from the combination of the short arm geometry and the Hard material, rather than from the geometry alone.

For the stated setup recommendation, the short Hard CFF2™ suspension arms should be used in combination with the #301028 HUDY Spring Steel™ 1.2mm Chassis. This product is the right front lower arm only, identified for suggested compatibility with the XRay X4 CFF2 suspension arrangement.
