For racers after consistent chassis behaviour, the XRAY 301572 Aluminium Upper Clamp is a solid upgrade choice. Made for the X4 2023 family, it is produced from Swiss 7075 T6 aluminium to hold precise tolerances under race conditions.
This grade of aluminium offers a useful balance of rigidity and manageable weight, helping reduce unwanted flex at the mount points while maintaining durability over time.
Machining accuracy ensures the clamp aligns with the XRAY X4 2023 suspension locations, supporting intended roll and steering reactions without forcing other setup changes.
Fit the clamp with uniform screw torque and check fasteners after initial running. Regular inspections will help catch any loosening from vibration or track impacts.
