Purpose made for the XRAY X4 family, the XRAY 302666 composite ball joint pack contains two front and two rear items sized for 4.9mm ball connectors. They help preserve suspension alignment and control through repeated use.
The XRAY 302666 pieces are moulded to suit front and rear upper arm fixtures on the X4. The front joints feature a clearance hole for body post screws, delivering a solid attachment that reduces unwanted movement.
Push the joints fully onto the 4.9mm balls and confirm there is no side play. These parts are ideal for scheduled service intervals or swapping out after crashes to retain consistent handling on track or off road.
