If you want a reliable upgrade for track use, the XRAY 352150-G Graphite Front Upper Arm Ball Joint Set brings enhanced durability and more precise steering to XB8 chassis setups. These parts are aimed at owners who need consistent control and long service life between maintenance cycles.
The graphite composition balances strength with low weight, reducing flex at the arm pivot while keeping unsprung mass down. That combination improves steering feedback and helps the car respond more predictably to setup changes.
These ball joints are made to match the XB8 geometry and mounting points, so they install cleanly and work with existing suspension components. They suit both routine replacement and incremental upgrades when refining suspension behaviour.
