XRAY 323116-H Solid Rear Lower Arm for XT2 2028 Composite 4-HOLE  [XR-323116-H]

This rear lower suspension arm is a 4-hole solid composite piece made to fit the XT2 2028 chassis. Produced in a hard composite blend, the arm aims to limit unwanted flex and provide a more stable platform on high-grip tracks.

Geometry notes: the component is shaped to accept the revised shock tower arrangement and includes two extra shock mounting locations, enabling use with updated shock tower setups and paired anti-roll bar configurations. Together these adjustments help manage roll without adding compliance.

Tuning role: use this arm when your setup requires reduced chassis flex and sharper turn-in, or when preparing the car for higher-traction events. Choosing between medium, hard, and graphite hardnesses helps dial front/rear balance and steering characteristics without altering core geometry.

Installation tips: confirm alignment to the revised shock tower mounting points and check anti-roll bar clearances during build. Make incremental setup changes and verify performance on the circuit to find the best balance.
