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

This rear lower suspension arm is a solid, 4-hole composite component built for the XT2 2028 chassis. Molded from a hard composite blend, the arm reduces unwanted flex to deliver a firmer, more direct response that helps stabilise handling on medium to high traction surfaces.

Geometry notes: the profile accepts the revised shock tower layout and offers two additional shock mounting positions, allowing the arm to work with updated shock tower setups and an anti-roll bar arrangement. That combination refines roll control without introducing extra compliance.

Tuning role: fit this arm when you want to cut chassis flex and achieve crisper turn-in, or when evaluating setups for higher-traction conditions. Swapping between hardness options (medium, hard, graphite) lets you tune front/rear balance and steering feel without changing suspension geometry.

Installation tips: verify alignment with the revised shock tower mounting points and confirm anti-roll bar clearances during assembly. Check settings trackside and make small adjustments incrementally to avoid over-tuning the setup.
