XRAY 302144-M X4 Medium CFF Upper Arm for Inner Shock  [XR-302144-M]

Sharper Handling for X4 Chassis

The XRAY 302144-M X4 CFF Upper Arm is engineered to provide a careful mix of rigidity and flex where the inner shock mounts on the X4. Manufactured with Carbon Fiber Fusion, it improves steering accuracy and helps maintain consistent vehicle behaviour through corners.

Balance Between Grip and Strength

This medium-hardness arm enhances both straight-line and lateral traction while preserving the structural toughness needed for racing. Its shape provides clearance for suspension movement without introducing radial play, resulting in steadier handling at speed.

Dual-Position Compatibility

The arm is compatible with front left and rear right positions, offering tuners a straightforward option for adjusting handling balance. Its versatility makes it useful across a range of track surfaces and conditions.

A practical upgrade for racers and hobbyists aiming to tighten steering response, the XRAY 302144-M CFF Upper Arm supports finer tuning of traction and stability.
