The XRAY 388521 clutch bell is a precision replacement made from HUDY steel for NT18 models, engineered to deliver consistent gear engagement and extended service life.
Manufactured with tight gear tolerances and careful machining, the XRAY 21T clutch bell maintains correct alignment and reduces drivetrain vibration for reliable on-track performance.
The package contains two 4x7x2.5mm bearings that reduce friction and wear, helping the clutch bell run smoothly and last longer in competitive use.
