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

This rear lower suspension arm is a solid, 4-hole composite component made to fit the XT2 2028 chassis. Molded in a hard composite material, the arm aims to cut unwanted flex and provide a firmer platform for consistent handling on medium and high grip tracks.

Geometry notes: the arm integrates with the revised shock tower layout and supplies two additional shock mounting points, enabling compatibility with updated shock towers and anti-roll bar setups. That pairing helps refine roll control while avoiding extra compliance.

Tuning role: choose this arm when reducing chassis flex and sharpening turn-in is the objective, or when experimenting with setups for higher-traction surfaces. Available hardness options—medium, hard, and graphite—allow tuning of front/rear balance and steering feel without changing suspension geometry.

Installation tips: check alignment to the revised shock tower mounting points and confirm anti-roll bar clearances during fitment. Validate settings on track and make incremental adjustments for best results.
