The Cusco front upper pillowball mount (B110/B120/GB122 F‑AJ) replaces the factory front upper shock mount with a precision pillowball unit. Intended to improve steering response and suspension control by reducing compliance, it’s a direct replacement that fits compatible Cusco mount patterns and supports more precise handling where a firmer top mount is desired.
