Model builders looking to refine handling can fit the XRAY 303232 Upper Arm Ball Universal to the X4 to achieve a cleaner steering response. Built from Hudy Spring Steel, these parts stand up to regular club and practice use while maintaining smooth articulation.
The XRAY 303232 units are manufactured to X4 tolerances so they seat accurately and work with original linkages. The precision pivot surfaces are black-coated to extend service life and reduce the need for frequent replacement.
