This graphite rear shock tower is built for the XRAY T4-20 and sold as Factory Pro part O-XCP002. Replacing the stock rear shock plate with graphite alters flex and stiffness versus common plastics, helping to maintain consistent suspension geometry under load.
Installation is straightforward on the T4-20, using the chassis factory mounting points for the rear shocks. When fitting, check eyelet alignment and body clearance, and use the original fasteners where possible. Tighten screws to the correct torque to avoid crushing the graphite edge.
Tuning notes: expect an increase in torsional rigidity that can change rear traction and roll characteristics. Make conservative adjustments to shock oil and spring choice and retest incrementally. Confirm full suspension articulation to ensure no binding before running at speed.
