XRAY 323116-G - XT2 Rear Lower Composite Suspension Arm (4-HOLE, Solid Graphite)  [XR-323116-G]

Rear solid lower arm for XT2

This XRAY rear lower suspension arm is an RC-scale replacement part for the XT2 platform, molded in a graphite composite to deliver a stiff, consistent pivot element for the rear suspension. The arm’s solid construction reduces unwanted flex under high lateral loads, helping maintain predictable steering response during aggressive cornering on high-traction surfaces.

The geometry includes four mounting holes and two additional shock mounting positions to match the revised XT2 shock tower layout, and it is compatible with the standard rear anti-roll bar arrangement used on the XT2 chassis. Fitment is limited to XT2-series rear suspension assemblies that accept the same mounting pattern.

As a tuning component, this solid rear lower arm is intended to increase stability and sharper steering feedback in high- to very-high-traction track conditions; it is one element among suspension, tyre choice, and shock tuning that a builder uses to dial handling. XRAY offers the arm in three hardness choices to suit different surface grip: medium, hard and graphite, allowing incremental changes in rear roll and responsiveness without altering tower geometry.
