XRAY 362113-H Hard Composite Front Lower Long Suspension Arm XB4A'20 Upgrade  [XR-362113-H]

Durable Suspension Upgrade for the XB4A'20

Made for the XB4A'20, the XRAY 362113-H hard composite front lower long suspension arm delivers increased strength and reliable performance. Its high-quality composite resists wear and suits a wide range of track conditions.

Longer Geometry to Improve Track Hold

The extended arm geometry enhances steering precision and traction on bumpy surfaces. Moving the lower shock mounts down shifts both the shocks and shock tower lower, reducing the car's center of gravity for steadier high-speed handling.

Wide Adjustment Range for Tuning

This arm gives you more setup options. The larger C-hub opening allows increased wheelbase variation over previous parts, while the broader shock mount accepts an eccentric pivot ball to fine-tune shock angle for traction and cornering balance.

Front Anti-Roll Bar Mounting Ready

A dedicated mounting point is included for an optional front anti-roll bar, so racers can dial in roll stiffness to match track conditions and driving style.
