Precision Composite Relief Ball Joint 6.8mm M4 (2 pcs) - XRAY 352666-G  [XR-352666-G]

Precision composite steering ball joint

The XRAY 352666-G relief ball joint is produced from a graphite composite mix that provides a good trade-off between durability and low friction. The relieved socket profile reduces binding points so the ball can move more freely, aiding predictable steering feel during use and in contaminated conditions.

Designed to accept a 6.8mm pivot ball or ball stud, the item ships as two pieces suitable for a left and right linkage. It is a scale RC part meant to be used with steering linkages and ball cup holders, not with any full-size vehicle application.

Fitting requires removing the existing ball cup from the turnbuckle or steering arm and pressing the new joint into the socket, ensuring the mating ball is clean and lightly lubricated if necessary. During setup, verify there is no binding across the travel and that end-play is within acceptable limits to preserve steering responsiveness.

These joints are ideal when you need steady articulation and less sticking in dirty conditions; they are appropriate for touring cars and comparable RC platforms for steering connections and small adjustable rods.
